In-depth guide · CampingSpirit
From Edmond Rostand’s villa in Cambo, via the Way of St James in Saint-Jean-Pied-de-Port, the vineyard terraces of Irouléguy and the Iraty plateau, to the Holzarte gorge, Mauléon and Sauveterre-de-Béarn: around 285 kilometres on narrow mountain-pass roads where sheep, cows and pottoks have right of way.
The spirit of the route
Leave the coast behind and you drive into the green Basque Country, where the roads get narrower and the pastures steeper. White farmhouses with red shutters cling to the slopes, every village square has a fronton for pelota, and the place names on the signs are bilingual. Beyond Saint-Jean-Pied-de-Port the real mountains begin: up hairpins full of sheep you reach the Iraty plateau, where one of Europe’s largest beech forests stretches across into Navarre. From the sliding door you watch mist rising from the valleys in the morning, the Pic d’Orhy in the last light in the evening, and at night all you hear are bells. In the Soule it gets quieter still: limestone gorges, a suspension bridge over the abyss, arcaded villages. This route demands patience at the wheel, respect for the weather and time for cheese, wine and conversations at the farm.
Stage-by-stage plan
1Stage 1: Cambo-les-Bains to Sare via Ainhoa (approx. 30 km)
- The drive
- From Cambo head west on the D918, past Espelette (the village is described in the CampingSpirit travel guide “Pine forest, shifting dune and Basque Country – by camper along the Atlantic coast to Saint-Jean-Pied-de-Port”) and on the D20 to Ainhoa. Continue on narrow, winding back roads through pastureland to Sare. A short stage with no passes, but with tight village through-roads and tractor traffic; under an hour of pure driving time, leaving a whole day for the villa, the village and the cave.
- Highlights & must-sees
- Villa Arnaga in Cambo-les-Bains: the neo-Basque country house Edmond Rostand had built after the success of “Cyrano de Bergerac”, with a museum and a strictly geometric French garden above the Nive; open seasonally, check times beforehand.
- Ainhoa: from the end of the village a footpath (a good 45 minutes) with Stations of the Cross climbs to the chapel of Notre-Dame-d’Arantzazu, with views over the Labourd hills to the sea.
- Grottes de Sare: a karst cave south of the village, guided tour with insights into prehistoric settlement and Basque mythology, plus a small museum; seasonal, check tour times.
- CampingSpirit overnight tip
-
Official campsite or RV park: In Sare there are the municipal aire and a campsite on the edge of the village (both described in the coastal travel guide). Quieter and closer to Ainhoa: Camping Xokoan near Dancharia on the Spanish border, a small site beside a stream. Cambo itself has an aire de camping-cars with water and waste services, handy for starting the day before.
Free camping or nature tip (where legal): In the Labourd, overnight stays in some village car parks are prohibited by municipal arrêté; Ainhoa is a listed village centre, and wild camping is banned anyway within 500 m of Monuments historiques. Use the aires and campsites; at the cave entrance and the villa, parking during the day is allowed, but overnight stays are not intended.
- Insider tip for campers
- Villa Arnaga sits on the slope above the town; park below and walk the last few metres. If you want to take the rack railway up La Rhune, you’ll find the details in the coastal travel guide – here the cave visit is worthwhile in the afternoon, when the sun is blazing outside or rain is coming. Fill up and empty in Cambo or Sare: service points are scarcer over the next few days.
2Stage 2: Sare to Saint-Jean-Pied-de-Port (Ascarat) (approx. 60 km)
- The drive
- Back via Ainhoa and past Espelette to Itxassou, then on the D918 up the Nive valley via Louhossoa and Bidarray to Ossès and Saint-Jean-Pied-de-Port. The D918 is well built but follows the river in bends; rock overhangs between Bidarray and Ossès. The side road to the Pas de Roland near Itxassou is narrow and unsuitable for large motorhomes. Around 1.5 hours of pure driving time.
- Highlights & must-sees
- Pas de Roland near Itxassou: a rock gateway above the Nive which, legend has it, Roland struck with his horse’s hoof – a short walk from the roadside, better reached on foot or by bike from Itxassou.
- Bidarray: the medieval arched bridge Pont Noblia over the Nive and the church high above the river; in summer, rafting trips start here.
- Saint-Jean-Pied-de-Port as a pilgrim town: follow the scallop-shell waymarks on foot through the Porte d’Espagne a little way up the Route Napoléon – after an hour the town lies below you, and you understand why pilgrims set off from here with respect for the first day.
- CampingSpirit overnight tip
-
Official campsite or RV park: Camping Narbaïtz in Ascarat, a good 2 kilometres west of Saint-Jean-Pied-de-Port on the road to Saint-Étienne-de-Baïgorry: electric hook-ups, sanitary facilities, seasonal. Next door is Europ’ Camping. The municipal aires in town are described in the coastal travel guide. On the way, Bidarray has a site on the Nive, Camping Amestoya.
Free camping or nature tip (where legal): Saint-Jean-Pied-de-Port is a Monument historique zone with citadel and town walls – overnight stays outside the aires are not tolerated. At the Pas de Roland and on the banks of the Nive there are no legal overnight spots; the lay-bys are narrow and are there for passing traffic.
- Insider tip for campers
- The Route Napoléon (D428) is a narrow mountain road full of pilgrims on foot – do not drive up it in a motorhome. In Saint-Jean-Pied-de-Port don’t cross the old town; the bypass takes you to the car parks. Refuel before the passes of the coming days: there are only a few petrol stations in the hinterland; you’ll find supermarkets in Saint-Jean-Pied-de-Port and Saint-Jean-le-Vieux.
3Stage 3: Ascarat to Ascarat via Irouléguy, Saint-Étienne-de-Baïgorry and Col d’Ispéguy (approx. 40 km)
- The drive
- On the D15 to Irouléguy and Saint-Étienne-de-Baïgorry, then on the D949 up to the Col d’Ispéguy (around 670 m) on the Spanish border: just under 9 kilometres and a good 500 metres of climbing from Baïgorry, averaging just under 6% with a maximum of about 8%, narrow in the upper section, with tight hairpins, hardly any passing places and grazing livestock on the road. A challenge for large vehicles; if you’re unsure, drive only as far as the first viewpoint hairpins. Return on the same road. With stops, half a day to a full day.
- Highlights & must-sees
- Vineyard terraces of the Irouléguy appellation on the slopes of the Jara and the Arradoy, with Tannat and Cabernet; tastings at the cooperative winery at the entrance to Saint-Étienne-de-Baïgorry or at individual winegrowers.
- Saint-Étienne-de-Baïgorry: the old single-arch bridge over the Nive des Aldudes, the church with wooden galleries and the Château d’Etxaus on the edge of the village.
- Col d’Ispéguy: views over the Baïgorry valley and across into Navarre’s Baztan valley; griffon vultures circle over the grassy slopes.
- CampingSpirit overnight tip
-
Official campsite or RV park: Second night in Ascarat (Camping Narbaïtz or Europ’ Camping). If you’d rather stay in Baïgorry: the municipal campsite L’Irouléguy lies by the river on the edge of the village, a few minutes’ walk from the centre, with electric hook-ups and water and waste services for motorhomes; open roughly from late March to late October.
Free camping or nature tip (where legal): There is a small car park at the Col d’Ispéguy, but the pass lies in pastureland; levelling jacks, awning or chairs count as camping behaviour there and are prohibited, and during the day the space belongs to day-trippers. On the Spanish side different rules apply, rather stricter in Navarre.
- Insider tip for campers
- Detour into the Aldudes valley (D948, narrow, further up the valley): this is where the black-and-white Kintoa pigs are raised, and you can buy ham and sausage directly from the producer. Drive Ispéguy in the morning: in the afternoon day-trippers and livestock trucks arrive. Go downhill in second gear and don’t let the brakes overheat.
4Stage 4: Ascarat to Forêt d’Iraty (Col de Bagargui) (approx. 35 km)
- The drive
- Via Saint-Jean-Pied-de-Port to Saint-Jean-le-Vieux, then on the D18 through the Laurhibar valley via Mendive up to the Col de Burdincurutcheta (1,135 m) and on across the plateau to the Chalets d’Iraty at the Col de Bagargui (1,327 m). From Saint-Jean-le-Vieux it is around 29 kilometres and a good 1,100 metres of climbing, averaging just under 4% with ramps over 11%. Single-track sections, cattle grids (passages canadiens), free-roaming livestock. Around 1 hour of pure driving time.
- Highlights & must-sees
- Forêt d’Iraty: loop trails through the beech and fir forest, which continues across the border into Navarre; in autumn the leaves turn copper-red.
- Cromlechs of Okabe: prehistoric stone circles on a hilltop north of the chalets, reachable on foot in about an hour.
- Pic des Escaliers and the view of the Pic d’Orhy (a little over 2,000 m), the first 2,000-metre peak of the Pyrenees from the west – ideal at sunset.
- CampingSpirit overnight tip
-
Official campsite or RV park: The Chalets d’Iraty’s nature campsite in the forest near the Col de Bagargui (commune of Larrau): around 50 pitches, two areas with electric hook-ups, waste water disposal, registration at the Chalets reception, where there is also a shop and restaurant; open roughly June to October. Around 5 kilometres away on the Lecumberry side is the Aire naturelle de camping-cars Etxola, with several dozen pitches in the countryside; ask about facilities and season in advance.
Free camping or nature tip (where legal): The plateau is common pasture of several communes and a Natura 2000 site; overnight stays are geared to the designated areas (campsite, Aire Etxola). Watch for prohibition signs at car parks and on tracks, don’t drive onto meadows and leave pasture gates as you found them.
- Insider tip for campers
- Iraty is often in fog even when the sun is shining in Saint-Jean-Pied-de-Port – then dipped headlights on, walking pace and expect cows behind every bend. In winter Iraty becomes a cross-country skiing area, and the roads can be closed after snowfall. Farms in the area sell Ossau-Iraty sheep’s cheese directly from the producer.
5Stage 5: Forêt d’Iraty to Larrau (Gorges d’Holzarte) (approx. 25 km)
- The drive
- From the Col de Bagargui down the D19 eastwards into the Soule: around 21 kilometres and about 1,000 metres of descent to the Auberge Logibar, averaging just under 5% downhill, with some sections considerably steeper according to drivers’ reports. Narrow, barely any crash barriers, grazing livestock, cyclists. One of the most demanding stretches of the route – drive early and take breaks in the few lay-bys. Shortly before Logibar the road to Larrau branches off.
- Highlights & must-sees
- Passerelle d’Holzarte: a suspension bridge around 70 m long, about 150 m above the Olhadubi gorge. The approach from the Auberge Logibar takes around an hour, steeply through forest; sturdy shoes needed, not for anyone with a fear of heights.
- Gorges d’Olhadubi: if you want to hike further, cross the bridge and continue above the gorge – a long, demanding day hike.
- Larrau: the last village before the Port de Larrau into Navarre, with views of the Pic d’Orhy; starting point for the summit hike.
- CampingSpirit overnight tip
-
Official campsite or RV park: Camping Ixtila in Larrau, a small site near the village with electric hook-ups and sanitary facilities; seasonal, call ahead. Alternatively further down the valley near Licq-Athérey or Tardets (see next stages).
Free camping or nature tip (where legal): Overnight stays at the Logibar car park are not intended; it serves hikers and fills up early in summer. The Holzarte gorge lies in a protected area: no fires, no drones, take your rubbish with you.
- Insider tip for campers
- Start the Holzarte hike before 9 am: at midday groups crowd onto the bridge. The passerelle is occasionally closed for a few days for maintenance work, and parking near the trailhead may be restricted – check the current situation beforehand with the Soule tourist office. The Port de Larrau into Spain is closed in winter and is not a good route for large motorhomes.
6Stage 6: Larrau to Tardets via Sainte-Engrâce (approx. 50 km)
- The drive
- On the D26 down the valley to Licq-Athérey, then on the D113 south through the narrow Uhaitza valley to Sainte-Engrâce – narrow, with pinch points at rocks and short climbs. Back to Licq and on the D26 to Tardets. Around 1.5 hours of pure driving time.
- Highlights & must-sees
- Gorges de Kakuetta: after a fatal rockfall, the famous ravine with its waterfall and cave has been closed to visitors for years. The commune is planning a new path running higher above the gorge, with viewpoints – check the current situation before you go and on no account enter on your own.
- Church of Sainte-Engrâce: a Romanesque building founded at the end of the 11th century, with richly figured capitals, in a valley basin beneath limestone walls.
- Gorges d’Ehujarre: a hike from Senta through a wild limestone gorge; alternatively a guided visit to the Salle de la Verna, one of the largest known underground chambers, by guided tour only with reservation.
- CampingSpirit overnight tip
-
Official campsite or RV park: Camping du Pont d’Abense on the Saison opposite Tardets: electric hook-ups, sanitary facilities, water and waste services; seasonal. On the edge of Tardets-Sorholus there is a municipal aire de stationnement for around 20 motorhomes. In Sainte-Engrâce, Camping Ibarra offers pitches on the valley floor.
Free camping or nature tip (where legal): In the narrow valleys of the Haute-Soule there simply isn’t the space for free standing; passing places on the D113 are not car parks. Overnight stays at the access to the closed Kakuetta gorge are not intended.
- Insider tip for campers
- In the Soule, autumn to spring is the season for the controlled burning of mountain pastures (écobuage): smoke can suddenly cut visibility, and roads are occasionally closed for short periods. Tardets is the last place with shops before the mountains – stock up on the way back. Combine the walk around the arcaded square with the path to the Chapelle de la Madeleine above the village.
7Stage 7: Tardets to Sauveterre-de-Béarn via Mauléon-Licharre (approx. 45 km)
- The drive
- On the D918 and D26 down the Saison valley to Mauléon-Licharre, then on departmental roads along the Saison northwards until it flows into the Gave d’Oloron at Sauveterre. Hilly country, well-built roads, with a few pinch points in the village centres. A good hour of pure driving time.
- Highlights & must-sees
- Château de Mauléon: a fortress with origins in the 12th century on the hill above the town, with views over the rooftops and the first Pyrenean ridges.
- Mauléon as the town of espadrilles: in the workshops and factory shops of the remaining manufacturers you can see how jute soles and canvas are sewn together; plus the Renaissance town mansion Hôtel d’Andurain de Maytie.
- Sauveterre-de-Béarn: the medieval bridge Pont de la Légende with its gate tower in the Gave d’Oloron, the church of Saint-André and the terrace above the river with views as far as the mountains.
- CampingSpirit overnight tip
-
Official campsite or RV park: Camping du Gave by the river in Sauveterre-de-Béarn, a small site with electric hook-ups and sanitary facilities, seasonal. In the village there is a small aire de stationnement for a few motorhomes. In the surrounding area, farms offer pitches, such as the aire at the Ferme Mignaburia. Near Mauléon, Camping Uhaitza Le Saison lies by the river in Garindein.
Free camping or nature tip (where legal): Around the castles of Mauléon and Sauveterre (Monuments historiques), wild camping is prohibited within a radius of 500 m. On the gravel banks of the Gave d’Oloron and the Saison the water rises quickly after rain in the mountains – don’t park there even during the day.
- Insider tip for campers
- In Mauléon don’t drive into the centre on the castle hill; the streets are steep and narrow; park below by the Saison. For onward travel, the A64 (toll) towards Pau or Bayonne is near Salies-de-Béarn. If you want to continue east, you’ll find the continuation in the CampingSpirit travel guide to the French Pyrenees from Pau to Ax-les-Thermes.
Camping practice & local rules
Wild camping & overnight parking
- France distinguishes between parking and camping: a motorhome may park wherever parking is allowed – for at most 7 days in the same place – provided no municipal arrêté prohibits it. Camping behaviour (levelling jacks, awning, table and chairs, emptying tanks) is prohibited outside campsites and aires. Blanket bans for entire communes are legally challengeable; what counts is the signage on site.
- Wild camping is prohibited, among other places, in sites classés, within 500 m of Monuments historiques (Ainhoa, Saint-Jean-Pied-de-Port, Mauléon, Sauveterre, Sainte-Engrâce), near drinking-water catchments and on riverbanks. In the Pays Basque many communes have issued additional bans on motorhomes in village and trailhead car parks.
- The high pastures (Iraty, Ispéguy, Bagargui) belong to the valleys’ grazing communities: don’t drive on grassland, close gates, keep dogs on a lead. Don’t feed livestock guardian dogs or pottoks; keep your distance.
- You can stay overnight legally at campsites, municipal aires, aires naturelles and at farms (France Passion, Bienvenue à la ferme). Apps: park4night, Campercontact, Camping-Car Park.
Waste disposal & supplies
- Water and waste services (“aire de services”, “borne”) are available in Cambo, Sare, Saint-Jean-Pied-de-Port, Tardets and Sauveterre; on the Iraty plateau and in Larrau, service points are rare or for guests only. Head into the mountains with a full fresh-water tank and empty waste tanks.
- Empty grey water and the cassette only at service points: in the karst areas of the Soule, waste water seeps quickly into the groundwater from which the villages draw their drinking water.
- Tap water is drinkable. Springs on the pastures are untreated and, because of the grazing animals, should not be drunk without a filter.
- Gas: French exchange cylinders (butane/propane) in supermarkets and many petrol stations; foreign cylinders are not exchanged. LPG pumps for filling refillable tanks (Dish/Euronozzle adapter) are more likely to be found around Bayonne than in the hinterland – search via app and top up beforehand. On Iraty, night-time temperatures drop sharply even in summer: propane instead of butane.
Vehicle size & traffic rules
- Speed limits: motorhomes up to 3.5 t and car-and-caravan combinations up to 3.5 t gross train weight as for cars – 130/110/80 km/h (motorway/expressway/country road, 90 where signposted), 50 in built-up areas, 110/100/80 in rain. Motorhomes over 3.5 t up to 12 t: motorway 110, dual carriageway 100, other roads 80, built-up areas 50, with a speed disc on the rear. Combinations over 3.5 t: motorway and expressway 90, other roads 80.
- Vehicles over 3.5 t, explicitly including motorhomes, need the “Angles morts” stickers on the sides and rear; fine €135. On passes and in villages, weight, length and access restrictions are signposted – the signs take precedence. Drive slowly over cattle grids.
- Mountain roads: the D18 and D19 over Iraty and Bagargui are narrow and steep, with ramps over 11%; the D949 to the Col d’Ispéguy is narrow with gradients of up to about 8%; not recommended for caravans. The Port de Larrau and the Iraty roads can be closed in winter; check the current situation with the Département Pyrénées-Atlantiques. In places designated as mountain communes by prefectural order, from 1 November to 31 March you must have winter tyres fitted or snow chains on board (Loi Montagne); which communes are affected is shown by the signage or by the Préfecture des Pyrénées-Atlantiques.
- Weather: Atlantic Pyrenean climate – fog and drizzle even in summer, afternoon thunderstorms, and with a south wind warm, dry föhn weather with gale-force gusts. On the high plateaus the weather can change within an hour.
- Tolls: the A63 (Bordeaux–Bayonne–Spain) and A64 (Bayonne–Pau) are toll roads; classes according to ASFA: class 2 over 2 m and under 3 m in height at ≤ 3.5 t, class 3 two-axle and from 3 m in height or over 3.5 t, class 4 three or more axles over 3.5 t or from 3 m. The route itself is toll-free.
- Crit’Air/ZFE: the zones remain in place after the Conseil constitutionnel struck down their nationwide abolition on 21 May 2026; each Métropole sets the classes itself. There is no known ZFE on the route; if you arrive via Bordeaux, a ban on unclassified vehicles applies there inside the Rocade. Order the sticker only via certificat-air.gouv.fr.
- Blood alcohol limit 0.5 per mille (new drivers 0.2); using a phone at the wheel is prohibited, even with a headset. A high-visibility vest for the driver and a warning triangle are compulsory. If you cross into Spain at the Col d’Ispéguy or Port de Larrau, Spanish rules apply there.
CampingSpirit packing & preparation checklist
- Check the rear fog light and take spare bulbs – on Iraty and Bagargui you often drive in the clouds.
- Wheel chocks and levelling ramps: the pitches in Larrau, Iraty and Tardets are sloping.
- Hiking boots with good tread and poles for the steep, often wet approach to the Holzarte bridge and the trails in the Iraty forest.
- Water filter or jerrycans: there is hardly any safe drinking water and few service points on the high pastures.
- Warm layers and a rain jacket: at 1,300 m the temperature drops noticeably at night even in summer, and drizzle comes without warning.
- Cool box or free space in the fridge for Ossau-Iraty cheese, Kintoa ham and Irouléguy wine straight from the farm.
As of 2026-10. Closures, fees and booking rules change: check official sources before you go.
