*Dunes as high as tower blocks, a valley that smells of sagebrush, and beyond it 14,000-foot peaks, Leadville and Independence Pass.*

## The spirit of the route

The San Luis Valley lies at 2,300 metres and is so wide that you can see the end of the road before you set off. To the east the Sangre de Cristo range stands like a wall, and in front of it lie the highest sand dunes in North America, a sea of sand with ripple patterns that you trudge up barefoot at sunset. In the evening a huge sky hangs over the plain; at night the Milky Way glows above your pitch. Then north: poplars along the Arkansas River, the Collegiate Peaks with Mount Elbert and Mount Princeton, Leadville at over 3,000 metres with brick façades from the silver era. At the end the road climbs over Independence Pass, one of the highest paved passes in Colorado, and winds down in tight hairpins to Aspen. Here you learn what a camper needs at altitude: patience, brakes, warm layers and early starts before the afternoon thunderstorms arrive.

## Stage-by-stage plan

### Stage 1: Alamosa to Great Sand Dunes National Park (approx. 55 km)

- **The drive:** From Alamosa east on US 160, then north on CO 150 to the national park at the foot of the Sangre de Cristo. The road is flat and straight, speed 55 to 65 mph, and wind from the valley is often strong. Pure driving time is about an hour; allow a whole day for the park.
- **Highlights & must-sees:**
  - Dune field in Great Sand Dunes National Park: the sand mountains rise to about 230 m above the valley; the climb has no marked trail and means hard going in loose sand. Best early in the morning or in evening light; at midday the sand can get very hot.
  - Medano Creek at the foot of the dunes: in spring and early summer the creek forms waves (surge flow) and serves as a beach; in late summer and autumn it is often dry – check the water level on nps.gov before your visit.
  - Starry sky: the park is designated a Dark Sky Park; in clear weather and at new moon, an evening walk is a good idea.
- **Official campsite or RV park:** Pinyon Flats Campground in the national park: simple sites among piñon pines and juniper, as of the latest information without electricity and without showers, with drinking water and toilets; reservations compulsory via Recreation.gov, open roughly from April to October; check vehicle dimensions on nps.gov beforehand. In the valley there is also San Luis Lakes State Park near Mosca with lake views and some sites with electricity; check facilities and availability with Colorado Parks and Wildlife.
- **Free camping or nature tip (where legal):** In the park, overnighting in the vehicle outside the designated sites is prohibited. On the adjoining National Forest and BLM land, simple sites and dispersed camping are possible in some places; access roads are often gravel and suitable only for vehicles with raised ground clearance. Read the Forest Service maps on the spot.
- **Insider tip for campers:** Zapata Falls Recreation Area (BLM) offers a small campground and a short trail to a waterfall in the mountain; the access road is winding and narrow for large motorhomes. Get water and food in Alamosa or Mosca; the range in the park is small.

### Stage 2: Great Sand Dunes to Poncha Springs (approx. 120 km)

- **The drive:** Back along CO 150 to US 160 and north on CO 17 through the valley (Mosca, Hooper, Moffat) to US 285 shortly before Villa Grove, then on US 285 over Poncha Pass (2,746 m) to Poncha Springs. Long straights, little traffic, wind and weather changes possible. Moderate climbs on Poncha Pass. Driving time about 2.5 hours.
- **Highlights & must-sees:**
  - Crestone (detour off the route) and Sangre de Cristo Wilderness: a village with Buddhist, Hindu and Christian centres at the foot of the mountains; walks and viewpoints.
  - Hot springs around Poncha Springs and Salida: there are several baths (such as Poncha Hot Springs); check opening times and prices beforehand.
  - Poncha Pass: a quiet pass with views of the Sangre de Cristo and the valley; good photo stops in clear weather.
- **Official campsite or RV park:** Along the way there are smaller campgrounds in Rio Grande and Pike-San Isabel National Forest; check specific names and opening status on Recreation.gov or with the Forest Service before you set off. In Poncha Springs and Salida there are private RV parks with hookups; Salida is about 10 kilometres away.
- **Free camping or nature tip (where legal):** San Isabel National Forest and BLM land at Poncha Pass allow dispersed camping, mostly for up to 14 days; observe fire bans and check access roads for motorhomes.
- **Insider tip for campers:** Poncha Springs is a good supply stop, with filling stations and supermarkets in Salida. Fill up with fuel and water before the mountains; prices rise in the high valleys.

### Stage 3: Poncha Springs to Buena Vista (approx. 55 km)

- **The drive:** Via US 285 and US 24 north through the Arkansas River valley between the Collegiate Peaks to the west and the Mosquito Range to the east, flat to undulating terrain with poplars, and golden aspens in autumn. The river is a rafting and fishing area. Driving time about 1 hour.
- **Highlights & must-sees:**
  - Collegiate Peaks: Mount Princeton (4,327 m), Mount Yale and Mount Harvard shape the valley; viewpoints on US 24 and on side roads.
  - Mount Princeton Hot Springs in Chalk Creek Canyon: thermal baths at the foot of the mountain; St. Elmo, a well-preserved ghost town further up the canyon, can be reached on gravel.
  - Arkansas Headwaters Recreation Area: rafting put-ins and trails along the Arkansas River; busy in summer.
- **Official campsite or RV park:** Arkansas Headwaters Recreation Area (Colorado Parks and Wildlife) manages several campgrounds along the river, including Ruby Mountain, Hecla Junction and Fisherman’s Bridge; check facilities, length limits and reservations before you set off. In the Collegiate Peaks area there are simple Forest campgrounds in San Isabel National Forest, such as Collegiate Peaks Campground on the Cottonwood Pass Road; check the status.
- **Free camping or nature tip (where legal):** Along the Cottonwood Pass Road and in Chalk Creek Canyon, dispersed camping is allowed in many places, with fire bans depending on the situation; access roads are in places steep and stony. In the Arkansas Valley itself, parking up in car parks and on riverbanks is often prohibited.
- **Insider tip for campers:** Buena Vista has filling stations, supermarkets and a dump station; fill up with water once more before the pass. The Cottonwood Pass Road is paved and open in summer, but steep, with tight hairpins – for large motorhomes only with experience.

### Stage 4: Buena Vista to Leadville (approx. 65 km)

- **The drive:** Via US 24 north along the Arkansas River and on to the high plateau at Leadville at around 3,100 m. Straight, fast sections, then a climb in waves; wind and cool night temperatures. Driving time about an hour; with stops, half a day.
- **Highlights & must-sees:**
  - Leadville: a former silver town with well-preserved brick buildings; at just over 3,000 m one of the highest towns in the USA. The National Mining Hall of Fame and Museum explains the history of mining.
  - Turquoise Lake: a lake west of town with a trail around the shore, kayaking and fishing; views of the Mosquito Range.
  - Mount Elbert: at 4,401 m the highest mountain in Colorado; easy to reach as a goal for mountain hikers, but only with altitude experience and weather monitoring.
- **Official campsite or RV park:** Turquoise Lake Recreation Area (San Isabel National Forest) with several campgrounds, such as Molly Brown, Baby Doe and May Queen Campground; reservations via Recreation.gov, check facilities and length limits beforehand. In Leadville there are private campgrounds; check selection and prices on the spot.
- **Free camping or nature tip (where legal):** Dispersed camping is allowed in many places in San Isabel and White River National Forest, mostly for up to 14 days; closures and fire bans apply in snow or dry conditions.
- **Insider tip for campers:** Leadville lies at 3,100 m: at night it can get cold to around freezing even in summer. Check your heating, gas and warm sleeping bags. Filling stations and supermarkets are in town.

### Stage 5: Leadville to Aspen (approx. 85 km)

- **The drive:** On US 24 north, then on CO 82 via Twin Lakes and over Independence Pass (3,687 m) down to Aspen. The pass has tight hairpins, road edges without guard rails, no shoulders and steep climbs; as of the latest information a length limit applies to long vehicles (about 35 ft between Twin Lakes and Aspen). The pass road is open in summer only and closed in winter, usually from November until spring. Driving time about 1.5 hours; vehicles over 35 ft must take an alternative route via Glenwood Springs.
- **Highlights & must-sees:**
  - Twin Lakes and Mount Elbert: two lakes at the foot of the mountains, views of the peaks and the historic village of Interlaken.
  - Independence Pass: viewpoint on the Continental Divide with a short loop trail over alpine tundra at 3,687 m; cool wind, afternoon thunderstorms possible.
  - Aspen: old town with Victorian buildings and access to Maroon Bells – a reservation and shuttle system applies to Maroon Bells in summer; check the details on the Forest Service website.
- **Official campsite or RV park:** On the west side there are White River National Forest campgrounds such as Lost Man Campground, Lincoln Gulch Campground and Difficult Campground; reservations via Recreation.gov, check vehicle sizes and status before you set off. The approach from the west is steep and narrow; better to avoid it with large vehicles.
- **Free camping or nature tip (where legal):** Dispersed camping in White River National Forest along the pass road is possible on some sections, but depends heavily on signage and rules; observe fire restrictions. In Aspen and in car parks, overnighting is prohibited.
- **Insider tip for campers:** Before the descent to Aspen, check your brakes and stay in a low gear. Aspen has only a few pitches for motorhomes; an alternative is campgrounds further down the Roaring Fork Valley, for example near Basalt or Carbondale. On the spot, watch for notices on parking and time limits.

## Camping practice & local rules

### Wild camping & overnight parking

- Dispersed camping in Colorado is mostly allowed on National Forest and BLM land for up to 14 days at the same spot, but not in national parks, towns and on many lakeshores. In Great Sand Dunes National Park, free camping is prohibited.

- Wildlife: black bears, elk and marmots; lock food in the vehicle at night. In the dune field, rattlesnakes and insects are possible.
- Altitude: almost all stages lie above 2,300 m; raise your daily targets slowly and drink plenty.

### Waste disposal & supplies

- There are dump stations in Alamosa, Salida, Buena Vista and Leadville and on some campgrounds; check location and fee beforehand.
- Drinking water: tap water is drinkable; in Great Sand Dunes National Park there are taps at the visitor center and on the campground.
- Empty grey water and chemical toilets only at disposal points.

- Weather: afternoon thunderstorms at altitude, strong wind in the valley, frost even in summer.
- Traffic law: a right turn on red after stopping is allowed where not prohibited; open alcohol containers prohibited; seat belt and child seat rules apply.

## CampingSpirit packing & preparation checklist

- Wheel chocks and levelling wedges: many sites are sloped, and on high plateaus the wind is strong.
- Warm layers, a hat and a down jacket: night temperatures near Leadville are often close to zero degrees.
- Sun protection, sunglasses and water bottles: in the dune field the sun burns and the sand is hot.
- Sturdy shoes and a head torch for stargazing and paths in the dark; gaiters against sand are useful.
- Offline maps and printed reservations: reception is poor in the San Luis Valley and at the pass.

_As of 2026-09. Closures, fees and booking rules change: check official sources before you go._
