Rocky Mountain National Park Camping

Campers who prioritize a quieter, smaller-scale experience near the Fall River entrance — Aspenglen is the right pick for anyone who finds Glacier Basin too crowded and prefers walk-to or tent-only sites.

Aspenglen is RMNP's smallest reservable campground at 48 sites, and its intimacy is the point — 6 walk-to sites and 15 tent-only nonelectric spots attract campers who want to feel slightly removed from the park's main traffic. The 50-foot vehicle cap means larger fifth wheels and Class A rigs should look to Glacier Basin instead. Booking dynamics here are distinctive: September is the hardest month to secure a site, with 26.2% of reservations planned 6+ months out — more advanced planning than any other month at this campground. July, counterintuitively, is the easiest month with 35.9% of bookings made last-minute. Winter camping is available in Loop-C on a first-come, first-served basis from October through late May for those willing to brave high-altitude cold.

Tent campers and groups who want the best access to Bear Lake Road trails and don't need hookups — Glacier Basin suits hikers who want to walk out of camp and onto iconic trails immediately.

Glacier Basin sits at 8,500 feet on the east side of the park and is the closest campground to the Bear Lake Road corridor — the park's most popular trail hub. With 74 tent-only sites, 63 standard sites, and 11 group sites, it serves the widest range of camping parties of any RMNP campground. The 90-foot vehicle maximum is the most generous in the park, yet there are no electric hookups, so self-contained RVs only. July is statistically the hardest month to book here, with 23.7% of reservations locked in 6+ months out — the highest long-lead rate of any campground in the dataset. August paradoxically offers the most last-minute opportunity at 34.3%. The campground opens May 22 for summer 2025.

Groups and families who want the park's largest campground with electric hookup options — but be aware Moraine Park is currently closed for a major infrastructure project with no confirmed reopen date.

Moraine Park is the park's anchor campground — 239 sites including 46 standard electric and 1 tent-only electric make it the only campground at RMNP with meaningful hookup infrastructure. A 60-foot vehicle limit opens it to most Class A rigs. However, Moraine Park is currently closed for the Headquarters East Utility Project, and no reopening date has been confirmed for summer 2025. Do not plan a trip around this campground without verifying current status on recreation.gov. When it does operate, demand is Very High every single day of the week and zero sites were available in our 14-day forward look — making it one of the most contested campgrounds in the Colorado Rockies.

West-side explorers and Trail Ridge Road enthusiasts — Timber Creek is the only campground on the park's west side, making it the right base for Kawuneeche Valley hikes and anyone coming from Grand Lake.

Timber Creek is unlike any other campground in this park — it's the sole campground on RMNP's west side, accessed via the Grand Lake entrance, and it holds just 7 standard nonelectric sites. That scarcity makes it deceptively competitive despite its small profile: all 7 sites are reservation-only during summer, and July and August together account for over 4,200 reservations in the dataset (though many of those reflect site-nights across the season). May is the easiest month to snag a spot, with 36.0% of reservations booked last-minute and only 2.3% secured 6+ months out — the lowest long-lead rate of any campground at RMNP. No vehicle maximum is listed, but the remote road access and small site count make this a poor fit for large RVs. If your itinerary includes the Kawuneeche Valley or you're crossing the park from the west, Timber Creek is the only option — book it the moment the window opens.
