Colorado RV Camping: Rocky Mountain National Park, Mesa Verde & the Million Dollar Highway

Colorado is the mountain state that demands repeat visits. Rocky Mountain National Park, Mesa Verde cliff dwellings, Black Canyon of the Gunnison, Great Sand Dunes, and the San Juan Skyway — all within a state that's also home to some of the best campgrounds in the western US. Here's how to plan a Colorado RV trip that does it justice without getting caught by the altitude, the mountain weather, or the size restrictions that trip up first-timers.

The RV Reality in Colorado

Colorado has significant terrain — passes over 12,000 feet, narrow canyon roads, and tight switchbacks. Most Colorado highways are absolutely fine for large motorhomes and fifth wheels. A few sections require attention:

• Million Dollar Highway (US 550): Winding, steep, no guardrails on sections. Legal for RVs but not for the faint of heart in a large rig. Class A coaches up to about 38 feet can do it if the driver is experienced. In bad weather, wait or take the long way around.
• Trail Ridge Road (Rocky Mountain NP): The world's highest continuous paved road — open to RVs up to 35 feet. Stunning. Some campgrounds near the park have size restrictions.
• Rocky Mountain NP reservation system: The park requires timed entry reservations from late May through mid-October. Book on recreation.gov months in advance.
• Altitude sickness: Genuinely an issue at Colorado altitudes. Denver is 5,280 feet; most mountain towns are 7,000-10,000 feet. Give yourself a day to acclimate. Headaches, fatigue, and shortness of breath are common the first 24-48 hours. Drink more water than you think you need.

Rocky Mountain National Park

RMNP is the centerpiece of most Colorado RV trips — 415 square miles of alpine scenery, 300 miles of hiking trails, and wildlife that includes elk, moose, bighorn sheep, and black bears.

Campgrounds:

• Moraine Park Campground: Largest in the park (244 sites), accepts RVs up to 35 feet, has hookup sites. Book on recreation.gov 6 months in advance for summer visits.
• Glacier Basin Campground: No hookups but accepts RVs up to 35 feet. Generator hours apply.
• Aspenglen Campground: Near Fall River entrance, accepts RVs up to 30 feet.

Alternative: Stay in Estes Park. The gateway town has multiple commercial campgrounds and RV parks with full hookups. Use Estes Park as a base and drive into the park daily (use the free shuttle from park-and-ride lots to avoid parking issues).

Best time to visit: Late September through early October for fall aspen color and elk rut. The bugling elk are one of the great wildlife spectacles in North America. July-August for wildflowers and full summer access. Avoid the park on summer holiday weekends — the crowds are severe.

Mesa Verde National Park

Mesa Verde is unlike any other national park — an ancient Ancestral Puebloan city built into cliff faces, preserved in extraordinary condition. Cliff Palace (the largest cliff dwelling in North America) and Balcony House are tour-required sites worth planning around.

RV considerations: The road from the park entrance to the main campground climbs steeply to 8,572 feet with tight turns — RVs over 35 feet are not recommended on the Wetherill Mesa road. Morefield Campground near the park entrance is the primary RV option: large sites, hook-up sites available, store and showers on site.

Book tours in advance: Cliff Palace and Balcony House tours sell out weeks ahead in summer. Book on recreation.gov when you book your campsite.

The San Juan Skyway and Million Dollar Highway

The 236-mile San Juan Skyway is one of America's great scenic drives — a loop through the most dramatic part of the Colorado Rockies connecting Durango, Silverton, Ouray, Ridgway, Telluride, and Cortez.

US 550 (Million Dollar Highway): The Ouray-to-Silverton section is the heart of the loop — 25 miles of hairpin turns with drops of thousands of feet and no guardrails on the outside edges. It's legal for RVs, and experienced drivers do it regularly. Tips: go early morning when traffic is lightest, take the uphill lane turns slowly, and pull over if you get nervous — there are turnouts. In rain, snow, or construction, consider the alternate route via US 160.

Best stops:

• Ouray, "Switzerland of America": Hot springs in a mountain cirque. Ouray Hot Springs Pool is excellent. Small town, great food, beautiful setting.
• Silverton: A restored mining town at 9,318 feet. Take the Durango & Silverton Narrow Gauge Railroad from Durango for a spectacular canyon approach.
• Telluride: One of Colorado's most beautiful mountain towns — accessible from Ridgway or via the Mountain Village gondola. Free gondola, stunning box canyon setting.

Great Sand Dunes National Park

North America's tallest sand dunes rising from a mountain valley — one of Colorado's most surreal landscapes. Accessible in RVs up to 35 feet at Piñon Flats Campground (within the park). The dunes are climbable; go early before the sand surface heats up to scorching temperatures by midday.

Black Canyon of the Gunnison

One of the most dramatic canyon views in North America — 2,700 feet deep with walls so narrow that sections receive only 33 minutes of sunlight per day. South Rim Campground accepts RVs (full hookups available in the South Rim loop). The North Rim is accessible only via an unpaved road — not recommended for large RVs.

Colorado RV Trip Logistics

Weather: Mountain weather changes fast. Afternoon thunderstorms are nearly daily in July and August above treeline. Plan hikes for morning and be off exposed ridges by noon. Snow is possible at high elevations any month of the year.

Fuel: Fill up in larger towns. Mountain towns often have limited fuel options and higher prices. Diesel is available at most truck stops in I-25 and I-70 corridors.

Best RV parks near parks: Durango KOA (Mesa Verde access), Estes Park KOA (Rocky Mountain NP), Alamosa (Great Sand Dunes access).
