*Around 470 kilometres from Huesca via the castle of Loarre and the Mallos de Riglos into the canyons of the Sierra de Guara, through the vineyards of the Somontano to Spain's smallest cathedral town and up along the Cinca reservoirs to Aínsa – a route for anyone who wants to explore the foothills of the Pyrenees in short stages.*

## The spirit of the route

Between the plain of Huesca and the 3,000-metre peaks lies a land that most people only drive through on their way to the high Pyrenees. Yet here it folds into reddish conglomerate towers into which rivers have cut narrow gorges, and on almost every rocky spur stands a castle or a Romanesque bell tower. In the morning the griffon vultures spiral up over the Mallos, at midday the air shimmers over cereal fields and almond groves, and in the evening it smells of thyme, rosemary and warm stone. From the sliding door you see the battlements of the castle above the plain at Loarre, the limestone walls of the Mascún at Rodellar, and the collegiate church on its rock above the Río Vero at Alquézar. In between: rows of Somontano vines, green reservoirs and villages with barely a hundred inhabitants. If you drive slowly, get up early and spend the midday heat in the shade, you experience Alto Aragón as it is: quiet, austere and steeped in history.

## Stage-by-stage plan

### Stage 1: Huesca to Loarre (approx. 40 km)

- **The drive:** In the morning, explore Huesca's old town on foot, then leave the city to the north-west on minor roads at the foot of the Sierra de Loarre via Bolea to Loarre. Flat to gently rolling through cereal fields and almond groves, well surfaced; pure driving time just under an hour. Beyond the village the narrow access road winds about 5 km up to the castle in hairpins – take it slowly in large vehicles, as oncoming traffic appears unexpectedly on the bends.
- **Highlights & must-sees:**
  - Huesca Cathedral: a Gothic building on the highest point of the old town, with the 16th-century alabaster high altar by Damián Forment; from the tower the view reaches the Pyrenees.
  - San Pedro el Viejo: a Romanesque monastery with a cloister and the royal pantheon where Ramiro II “the Monk” and Alfonso I of Aragon are buried.
  - Castillo de Loarre: one of the best-preserved Romanesque castles in Europe, from the 11th century, high above the Hoya de Huesca; the light is best in the late afternoon.
- **Official campsite or RV park:** Camping Castillo de Loarre on the road between village and castle, among pines and holm oaks with a view over the plain, with electricity and sanitary facilities; check the season and facilities in advance. If you want to stay in Huesca, use the municipal motorhome area (Área de autocaravanas) on the western edge of the city centre with water and waste disposal, right next to Camping San Jorge; another Área with water and waste disposal is in Bolea.
- **Free camping or nature tip (where legal):** Wild camping is prohibited in Aragon. Sleeping in a legally parked vehicle is possible under Spanish traffic law, as long as nothing extends beyond the vehicle's outline and nothing is discharged. The castle car park at Loarre is for visitors – for the night, it is better to use the nearby campsite.
- **Insider tip for campers:** Huesca's old town is narrow and partly traffic-calmed; leave the camper at the Área or on the edge of town and walk. Refuel and shop in Huesca before setting off – the choice in Loarre and Ayerbe is small. The castle charges admission and has varying opening hours; check in advance.

### Stage 2: Loarre to Agüero via Riglos and the Embalse de La Peña (approx. 60 km)

- **The drive:** From Loarre to Ayerbe, then on the A-132 north-west into the Gállego valley. Short detour to Riglos on a narrow spur road, then on via Murillo de Gállego to Agüero and along the Embalse de La Peña. Hilly; the A-132 is well surfaced, the spur roads to Riglos and Agüero are narrow. About 1.5 hours' driving time without stops.
- **Highlights & must-sees:**
  - Mallos de Riglos: conglomerate towers up to around 300 m high above the village, a climbing classic and home to a large griffon vulture colony; the circular walk around the Mallos takes a good two hours.
  - Agüero: smaller, rounder Mallos right behind the village and the Romanesque church of Santiago on the slope above, with expressive capitals.
  - Embalse de La Peña: the reservoir on the Gállego, which the A-132 runs alongside; plus, in Ayerbe, the Palace of the Marqueses and the interpretation centre on Santiago Ramón y Cajal, who spent part of his childhood here.
- **Official campsite or RV park:** Camping Agüero on the edge of the village below the Mallos, simple and quiet, and Camping Armalygal near Murillo de Gállego, a centre for rafting on the Gállego. In Ayerbe there is Camping La Banera. Check the season, electricity and water and waste disposal in advance; some sites are only open from spring to autumn.
- **Free camping or nature tip (where legal):** In Riglos itself parking is scarce, and the spaces at the village entrance belong to climbers and hikers during the day; camping behaviour is not tolerated. After wildfires, roads, paths and tracks may be closed – check in advance and always respect barriers.
- **Insider tip for campers:** After wildfires, roads and paths in the Riglos area and the Gállego valley may be closed; before setting off, check current road conditions with the DGT or the Government of Aragon. Riglos is already mentioned in the CampingSpirit guide to the Spanish Pyrenees – here the quieter evening in Agüero is the main reward.

### Stage 3: Agüero to Rodellar (Sierra de Guara) (approx. 110 km)

- **The drive:** Back via Murillo and Ayerbe on the A-132 to Huesca, past the city to the east and on minor roads along the southern edge of the Sierra de Guara through Abiego to Bierge. From Bierge the narrow road follows the Alcanadre via Las Almunias to Rodellar: around 20 km with many bends, rock overhangs and hardly any passing places. A good 2.5 hours' driving time.
- **Highlights & must-sees:**
  - Bierge on the Río Alcanadre: in summer a bathing spot at the weir below the village, starting point for the Peonera gorge.
  - Barranco del Mascún near Rodellar: a footpath into the canyon to rock arches and caves, doable without rope or wetsuit as long as the stream carries little water.
  - Griffon vultures and, with luck, bearded vultures over the walls of the Mascún – in the early morning, when the thermals begin.
- **Official campsite or RV park:** In Rodellar there are Camping Mascún and Camping El Puente, both geared to climbers and canyoning groups, with electricity and sanitary facilities. There are further campsites around Bierge. In July and August it is full – book ahead, and check beforehand whether the access road is suitable for your vehicle.
- **Free camping or nature tip (where legal):** Rodellar lies in the Sierra y Cañones de Guara Natural Park; camping and overnight stays on tracks and trailhead car parks are not permitted there. There is no room for motorhomes in the village – leave the camper at the campsite and walk.
- **Insider tip for campers:** The road to Rodellar is a challenge for long or tall vehicles; with an over-cab motorhome over seven metres, better stay in Bierge. Refuel in Huesca or Barbastro: there is no filling station in the Sierra de Guara. In high summer, drive in the morning hours; at midday temperatures on the southern edge of the Sierra often climb well above 35 °C.

### Stage 4: Rodellar to Alquézar (approx. 40 km)

- **The drive:** Back to Bierge, then via Adahuesca and Radiquero to Alquézar. A narrow, winding country road through holm oaks, almonds and olives, without major gradients; a good hour of pure driving time. The last stretch before Alquézar is tight, and vehicles are not allowed into the village itself.
- **Highlights & must-sees:**
  - Pasarelas del Río Vero: a circular walk of around 3 km over walkways and steps through the gorge below Alquézar, to be walked in one direction; ticket required, book online in advance at weekends and in summer.
  - Colegiata de Santa María on the rock above the village, on the site of the Moorish castle, with cloister and murals.
  - Rock art of the Río Vero (UNESCO World Heritage): guided tours to the rock shelters start from the interpretation centre in Colungo.
- **Official campsite or RV park:** Camping Alquézar on the edge of the village and Camping Río Vero a little further down, both with electricity and sanitary facilities; check the season in advance. At the village entrance there is a car park with an area for motorhomes, but without water and waste disposal; at weekends and in summer it fills up quickly.
- **Free camping or nature tip (where legal):** Wild camping is not allowed around Alquézar and in the Natural Park. The motorhome area at the village entrance is for parking; if you stay overnight there, follow the rules for correct parking – nothing beyond the vehicle's outline, resting only on the tyres (levelling chocks allowed), nothing discharged – and the municipality's signs.
- **Insider tip for campers:** Canyoning in Guara only with knowledge of the Natural Park's rules: some gorges are closed all year, others at certain times, group size is limited (usually eight, ten people in the Peonera and the Vero), groups must keep at least ten minutes apart, a full wetsuit is mandatory in many gorges, and the Natural Park advises against night descents. If you have no experience, book a licensed guide in Alquézar or Bierge. Walk the Pasarelas in the morning hours: at midday the heat builds up in the gorge.

### Stage 5: Alquézar to El Grado via Barbastro (approx. 50 km)

- **The drive:** From Alquézar down into the hills of the Somontano to Barbastro, then on the N-123 north-east to El Grado on the reservoir of the same name. Flat to rolling country roads through vineyards, well surfaced; pure driving time a good hour. Barbastro's old town is narrow and unsuitable for motorhomes.
- **Highlights & must-sees:**
  - Barbastro Cathedral: a late Gothic hall church from the 16th century with a high altar on which Damián Forment worked, and the Diocesan Museum next door.
  - Espacio del Vino in Barbastro: the interpretation centre of the D.O. Somontano with tastings, a good introduction before visiting a winery.
  - Somontano wineries between Barbastro and Salas Bajas, some with modern architecture; visits by appointment only.
- **Official campsite or RV park:** Área de autocaravanas El Grado, a municipal site with water and waste disposal, quietly located near the reservoir. Barbastro also has an Área with water and waste disposal. Check fees and maximum stay on site.
- **Free camping or nature tip (where legal):** Camping is prohibited on the shore of the Embalse de El Grado and on the access tracks; checks take place mainly in summer. For the night, use the municipal Áreas.
- **Insider tip for campers:** If you want to taste wine in the Somontano, park the camper beforehand or share the driving with your partner: Spain's limit is 0.5 per mille, 0.3 for novice drivers. Barbastro has large supermarkets and filling stations on the edge of town – the last good supply point before the uplands of the Ribagorza.

### Stage 6: El Grado to Benabarre via Graus and Roda de Isábena (approx. 85 km)

- **The drive:** On the N-123 to Graus, then north through the Isábena valley via Capella and La Puebla de Roda to the turn-off for Roda de Isábena. The last stretch climbs narrow and winding to the village on its mountain spur; car park before the village. Back to Graus and east on the winding N-123 through the hill country to Benabarre. About 2 hours' driving time.
- **Highlights & must-sees:**
  - Graus: Plaza Mayor with painted façades and arcades, and above it on the rock the Basílica de la Virgen de la Peña.
  - Roda de Isábena: a village with only a few dozen inhabitants but a Romanesque cathedral – the former episcopal church of the County of Ribagorza, with crypt and cloister; the cathedral is shown on guided tours, the cloister can be visited freely.
  - Benabarre: the old capital of the Ribagorza with a rebuilt castle on the hill and a view over the hill country to the Pyrenees.
- **Official campsite or RV park:** Camping Benabarre on the edge of town, with electricity, sanitary facilities and water and waste disposal; check the season in advance. In the Isábena valley, Camping Isábena near La Puebla de Roda is an alternative if you want to stay closer to Roda.
- **Free camping or nature tip (where legal):** Roda de Isábena is too small for overnight guests in motorhomes – the car park before the village is for visits only. In the hill country of the Ribagorza, as everywhere in Aragon: parking yes, camping no.
- **Insider tip for campers:** In Roda, do not drive into the village: the lanes and turning spaces are too tight for campers. Guided tour times for the cathedral are limited; ask in advance at the Ribagorza tourist office or in Graus. Refuel in Graus – there is no filling station in the Isábena valley.

### Stage 7: Benabarre to Aínsa via the El Grado and Mediano reservoirs (approx. 85 km)

- **The drive:** Back to Graus and El Grado, then north on the A-138: the road follows the Cinca along the El Grado and Mediano reservoirs to Aínsa. Well surfaced, winding above the shores; pure driving time just under 1.5 hours. Looking north, the high Pyrenees draw close.
- **Highlights & must-sees:**
  - The Torreciudad shrine high above the Embalse de El Grado, visible from far away.
  - Torre de Abizanda: an 11th-century Romanesque defensive tower above the Cinca, with a view of the Sierra de Guara.
  - Embalse de Mediano: when the water level is low, the church tower of the flooded old village of Mediano rises out of the lake – viewpoint on the A-138.
- **Official campsite or RV park:** Camping Aínsa on the edge of town with electricity, sanitary facilities and water and waste disposal; Aínsa is only the end point here, and more on the old town is in the CampingSpirit guide to the Spanish Pyrenees. If you would rather stay by the reservoir, you will find further campsites between Mediano and Aínsa.
- **Free camping or nature tip (where legal):** Camping is prohibited on the shores of the reservoirs; bathing spots and shore tracks are checked in summer. For the night, use a campsite or Área.
- **Insider tip for campers:** From Aínsa the roads continue to Ordesa, Bielsa and into the Benasque valley – the high Pyrenees are covered in the CampingSpirit guide to the Spanish Pyrenees. If you want to return to Huesca, take the A-138 to Barbastro and from there the A-22.

## Camping practice & local rules

### Wild camping & overnight parking

- The basic Spanish principle: sleeping in a legally parked vehicle is allowed, but camping with anything that extends beyond the vehicle's outline is not. Since 1 October 2026, Real Decreto 518/2026 (new Art. 92.4 of the Reglamento General de Circulación) explicitly defines when a motorhome is correctly parked: no parts beyond the vehicle's outline, resting only on the tyres (levelling chocks allowed), no discharging of liquids. Municipalities may still regulate parking times, zones and maximum stays, but according to the DGT may not impose penalties solely on the basis of vehicle type; rules for protected areas and coasts apply independently of this. Local implementation may take time – follow the signs.
- Aragon prohibits wild camping in principle (Reglamento de Acampadas, Decreto 61/2006); exceptions exist only for registered hiking and high-mountain bivouacs and authorised group camps, not for vehicles.
- In the Sierra y Cañones de Guara Natural Park, camping outside campsites is prohibited. Canyoning is subject to the Natural Park's own rules: some gorges closed all year, others at certain times, limited group size, at least ten minutes between groups, wetsuits mandatory in many gorges, night descents discouraged; in the Canal del Palomo, bathing in the pools is prohibited.
- After wildfires, roads, paths and tracks may be closed – check in advance; closures also apply to hikers.
- You can stay overnight legally at campsites and in the municipal Áreas de autocaravanas (Huesca, Bolea, Barbastro, El Grado). Apps: park4night, Campercontact, Áreas AC.

### Waste disposal & supplies

- Water and waste disposal is called “área de autocaravanas” or “punto de vaciado”; on this route you will find it in Huesca, Bolea, Barbastro and El Grado as well as at most campsites. There is no public station in the Sierra de Guara itself.
- Empty grey water and cassettes only at stations – discharging liquids in car parks has explicitly been a parking offence since RD 518/2026.
- Tap water in the municipalities is usually drinkable; look for “agua potable”. In summer, carry enough water on board: there are hardly any fountains in the Sierra de Guara, and the heat is dry.
- Gas: foreign cylinders are neither exchanged nor refilled in Spain. Autogas (GLP) is available at some larger filling stations, for example in the Huesca area; not in the mountain villages. Carry a Dish adapter and set off with a full tank.

### Vehicle size & traffic rules

- Speed limits: motorhomes up to 3.5 t 90 km/h outside built-up areas, 120 km/h on autopista and autovía; over 3.5 t and vehicle combinations 80 and 90 km/h respectively. In built-up areas, 30 km/h applies on roads with one lane in each direction.
- Low-emission zones: Spanish cities with over 50,000 inhabitants, including Huesca, must set up low-emission zones (ZBE); so far Huesca relies on the access control of its old town. Check the current status with the city before travelling. Barbastro and the other places on the route are smaller.
- Tolls: no vignette. The A-22 between Huesca and Barbastro is a toll-free autovía; the rest of the route runs on country roads.
- Mark projecting loads, such as bikes on a rear rack, with the red-and-white V-20 warning panel (50 × 50 cm). The connected V16 warning light is mandatory for Spanish vehicles and a sensible addition for foreign ones; keep a high-visibility vest within reach.
- Blood alcohol limit 0.5, 0.3 for novice drivers; using a phone while driving is prohibited. Open fires are prohibited in Aragon during the fire-risk season in and around woodland, including at barbecue sites; take particular care in dry summers and only cook inside the vehicle.

## CampingSpirit packing & preparation checklist

- Levelling chocks instead of jacks – Áreas and campsites in Guara are often uneven, and jacks in car parks have been a parking offence since RD 518/2026.
- Binoculars for the griffon vultures of Riglos and Rodellar and the bearded vultures over the walls of the Sierra de Guara.
- Reflective sun-shade mats for the windscreen and a 12 V fan: in summer, temperatures in the Somontano often climb well above 35 °C, and shade is scarce.
- Water container with a hose adapter and a second drinking-water supply for the days in Guara without services.
- Trekking sandals or water shoes for the streams and bathing spots of Bierge and Rodellar; for real canyoning, a wetsuit, helmet and harness, or a guide.

_As of 2026-10. Closures, fees and booking rules change: check official sources before you go._
