The Hardest Campgrounds to Book in the U.S. Right Now

Based on Campsite Odds' analysis of Recreation.gov reservation history, Haleakālā National Park's wilderness cabins in Hawaii, and a cluster of small U.S. Forest Service campgrounds in Colorado's White River National Forest, rank among the hardest campsites to book in the country — all scoring a perfect 10/10 difficulty for July, meaning they're typically gone within the first day the booking window opens.

• 142 campgrounds nationwide score a perfect 10/10 (“lottery-hard”) for July in Campsite Odds' latest data.
• Colorado's White River National Forest alone places three campgrounds in the hardest tier: Silver Queen, Silver Bar, and Maroon Bells Amphitheatre.
• Small site counts, not just fame, drive the difficulty — most of the hardest campgrounds have very few individual sites.
• Nearly a third of the hardest campgrounds nationwide are group sites — see our dedicated breakdown of why.
• “Lottery-hard” reflects demand sustained across 3 fiscal years of Recreation.gov history, not a one-time fluke.

What Makes a Campground “Lottery-Hard”?

Campsite Odds rates a campground 10/10 (the “lottery-hard” label) only when it consistently sells out within a small share of its 6-month booking window across multiple recent seasons — see what the booking-difficulty score actually means and the sellout-speed badges explained for the full mechanic. Every campground on this list carries an “at-open” sellout-speed rating, meaning most of a season's reservations are typically claimed the very day the window releases.

The Hardest Campgrounds to Book This July

• Haleakālā National Park Cabin Permits — Haleakālā National Park, HI — wilderness cabins on a volcanic crater rim, with extremely limited capacity and iconic sunrise-hike access
• Silver Queen Campground — White River National Forest, CO — steps from a popular 14er trailhead near Aspen
• Silver Bar Campground — White River National Forest, CO — neighboring Silver Queen, same trailhead corridor
• D.H. Day Group Campground — Sleeping Bear Dunes National Lakeshore, MI — the park's only group site
• Hunter Campground — Bighorn National Forest, WY — small high-country campground
• Hornswoggle Group Campground — Tahoe National Forest, CA — Sierra Nevada group site
• Cataloochee Group Camp — Great Smoky Mountains National Park, NC — sole group site in a historic valley
• Maroon Bells Amphitheatre — White River National Forest, CO — steps from Colorado's most-photographed peaks
• Big Elk — Caribou-Targhee National Forest, ID
• Caribou Creek Cabin — Chugach National Forest, AK — remote Alaska rental cabin

Why Does Colorado's White River National Forest Show Up Three Times?

Proximity to Aspen and the Maroon Bells, popular 14er trailheads, and small site counts combine to concentrate demand onto a handful of campgrounds. Browse White River National Forest or Colorado on Campsite Odds to see how every campground in the area compares side by side.

Is This a National Park Problem or a National Forest Problem?

Both agencies produce extreme outliers — this list splits roughly evenly between National Park Service and Forest Service sites. But the broader pattern runs deeper: our analysis of national forest vs. national park booking difficulty found that Forest Service campgrounds skew harder across the board, not just at the extremes.

How to Actually Get One of These Sites

3. Set a cancellation alert immediately if you miss the window — reservations get cancelled even at lottery-hard campgrounds.
4. Check this month's easiest campgrounds if you're open to a nearby alternative instead.
