Grand Teton National Park packs some of Wyoming's most dramatic scenery into a compact, wildly popular camping circuit — Jackson Lake sunsets, Teton Range silhouettes, and wildlife corridors that put bison and moose within yards of your tent. With 790 total sites across 9 campgrounds and zero availability in the next 14 days across every single one, this is one of the most competitive parks in the national park system to book. Demand is Very High every day of the week at every campground, so the campers who secure sites here plan aggressively — or know exactly when to catch a cancellation.
We analyzed 96,381 reservations across all 9 Grand Teton campgrounds to surface exactly when sites open up, who books them, and how to time your shot.

Groups, families with RVs doing dry camping, and any camper who wants maximum flexibility — this is the park's largest campground with 340 sites and the widest variety of site types.
Colter Bay Campground is the park's biggest operation — 340 sites including 277 standard non-electric, 39 tent-only, 13 electric ADA-accessible sites, 10 group sites, and 1 RV non-electric site — all set among lodgepole pines a short walk from Jackson Lake. The 99-foot vehicle allowance makes it one of the most accommodating campgrounds for large rigs in the national park system, though hookup-seeking RV campers should head next door to Colter Bay RV Park. May is the most accessible month at 34.0% last-minute, while July tightens to 16.8% last-minute with 21.8% of reservations placed 6+ months in advance. Group sites make this the default choice for large parties camping in the park. Generator use is permitted on designated loops.
October offers the best shot at a last-minute site in Grand Teton — 36.8% of that month's 2,185 reservations were made within a week of arrival, the highest rate of any month. May is the next-best window at 27.8% last-minute across 8,817 reservations, and Jenny Lake specifically shows 47.1% last-minute availability in May. July is the hardest month across the board, with 19.0% of reservations locked in 6+ months ahead and only 16.9% left to last-minute bookers across 24,449 total bookings.
Grand Teton does not operate a comprehensive free shuttle system like Zion, so a personal vehicle is the practical way to move between campgrounds, trailheads, and the Moose Visitor Center. The park's main corridor along Teton Park Road and Highway 89/191 is accessible to most vehicles, though Colter Bay RV Park's 55-foot limit and Signal Mountain's 32-foot cap mean large rigs need to plan routes carefully. Boats accessing Colter Bay Marina End Ties should note the 30-foot vessel limit at that specific location.
Grand Teton charges $35 per vehicle for a 7-day entrance pass. Nightly camping rates vary by campground and site type — hookup sites at Colter Bay RV Park and electric sites elsewhere carry higher fees than standard non-electric sites. The America the Beautiful annual pass ($80) covers the entrance fee for the pass year and is worth it if you're visiting multiple federal lands. Note that camping fees are paid separately and are not covered by the pass.
Stay limits vary by campground: Jenny Lake enforces a strict 7-night maximum while most others allow 14 nights — a meaningful difference for longer trips. Cell service is limited throughout the park, particularly at Headwaters Campground at Flagg Ranch, so download offline maps before arrival. Jackson, Wyoming is the nearest full-service town for groceries and supplies, though Colter Bay Village has an on-site grocery store and restaurant that reduces the need for frequent supply runs during a Colter Bay-based stay.
