Grand Teton is one of the few national parks where you can wake up with the Teton range filling your RV's back window — but the campground you book decides whether you get full hookups, an electric site, or a quiet spot with no services at all. The park spreads RV camping across six campgrounds, and only one of them has full hookups inside park boundaries. Picking the right one comes down to your rig's length and how much you care about plugging in.
The short version:
- Colter Bay RV Park is the only in-park campground with full hookups — 102 pull-through sites up to 45 feet, plus back-in sites up to 30 feet, all with 20/30/50-amp service.
- Gros Ventre and Signal Mountain offer electric at select sites; Colter Bay Campground is mostly no-hookup; Lizard Creek has no hookups; Jenny Lake is tents-only and takes no RVs.
- RV length limits run from 25 feet at Lizard Creek and 30 feet at Signal Mountain up to 45 feet at Gros Ventre, Colter Bay, and Headwaters.
- Every park campground is reservation-only on Recreation.gov, so book as early as the rolling window opens — popular sites fill months out.
- Jackson, about a half-hour south, is the closest gateway for rentals, groceries, and full-hookup private parks if the in-park sites are gone.
Which Grand Teton campgrounds take RVs, and which have hookups?
Five Grand Teton campgrounds take RVs — Gros Ventre, Signal Mountain, Colter Bay (both the RV Park and the standard campground), Lizard Creek, and Headwaters just north at Flagg Ranch — but hookups vary a lot between them, and Jenny Lake is tents-only. The cleanest way to choose is to start with how much service you need, then check whether your rig fits.
It helps to group the campgrounds into three categories based on the hookups they provide.
Colter Bay RV Park and Headwaters Campground at Flagg Ranch offer full hookups, including water, sewer, and 20-, 30-, or 50-amp electrical service. Both can accommodate RVs up to 45 feet long, making them the best options for larger rigs or travellers who want full campground utilities.
Gros Ventre and Signal Mountain offer electrical hookups at select sites, but no sewer connections. Gros Ventre can accommodate RVs up to 45 feet, while Signal Mountain has a maximum RV length of 30 feet.
Colter Bay Campground and Lizard Creek are dry-camping options with no hookups. Dump stations are available either on-site or nearby. Colter Bay Campground allows RVs up to 30 feet, while Lizard Creek is better suited to smaller rigs up to 25 feet.
One common mistake is trying to book Jenny Lake Campground for an RV. Although it is one of the park’s most photographed campgrounds, it is tents-only and does not have space for motorhomes or trailers. RV travellers should consider Colter Bay or Gros Ventre instead, both of which offer mountain and lake scenery while providing enough room for a rig.
If you want to plug in and not think about your tanks, the full-hookup tier is a two-campground decision. If you're comfortable dry camping or running off an electric post for a few nights, the middle and no-hookup tiers open up quieter, more scenic sites — Signal Mountain in particular sits right on Jackson Lake.
Does Grand Teton have an RV park with full hookups?
Yes — Colter Bay RV Park is the only campground inside Grand Teton with full hookups, and it's built for larger rigs. It runs 102 pull-through sites that take RVs up to 45 feet, plus a smaller block of back-in sites up to 30 feet, and every site has water, sewer, and 20/30/50-amp electric. That makes it the default pick for anyone renting a Class A or a longer Class C who wants to arrive, level, and connect.
A few specifics worth knowing before you book. The RV Park is part of Colter Bay Village, so you're a short walk from a general store, a laundromat, pay showers, and the Jackson Lake marina — useful on a longer stay when you need to resupply without driving into town. It's run by the Grand Teton Lodge Company rather than the Park Service, but it still books through Recreation.gov like the other park campgrounds. For 2026 it's open May 4 through October 9.
Renters we talk to who want full hookups in the Tetons almost always end up here, because it's the only in-park option — and the pull-throughs go fast. If Colter Bay RV Park is full, the next full-hookup site north is Headwaters Campground at Flagg Ranch, between Grand Teton and Yellowstone, which also takes rigs up to 45 feet and runs early June into early October. Headwaters sits on the John D. Rockefeller Jr. Memorial Parkway, so it's a natural stop if you're driving the Grand Teton–Yellowstone loop.
What's the RV length limit at each Grand Teton campground?
Length limits at Grand Teton run from 25 feet up to 45 feet, so the single most important number before you book is your rig's total length — and for a rental, that's the length on the listing, not a guess. Here's how the campgrounds line up for 2026:
Read that table against your rental class. A camper van or a small Class B fits anywhere, including Lizard Creek and Signal Mountain. A 25-to-30-foot Class C clears every campground except where the back-in limit bites. A 35-to-45-foot Class A or large travel trailer is realistically a Colter Bay, Headwaters, or Gros Ventre rig — and at Signal Mountain you'd be over the limit. If you haven't rented yet and you know you want a specific campground, size the RV rental to the campground rather than the other way around.
One practical note that saves a scramble at pickup: confirm your rental's length with the owner before you arrive, and take a few photos of the rig at handoff. It documents the condition and gives you the exact dimensions you'll need at the campground entrance station.
How far ahead do you reserve Grand Teton RV camping?
Every campground in Grand Teton is reservation-only through Recreation.gov — there's no first-come, first-served RV camping left in the park — so the answer is "as early as you can." Reservations open on a rolling window ahead of each date, and the full-hookup sites at Colter Bay tend to be the first to disappear, especially for July and August weekends.
A few timing facts to plan around. The camping season is short: most campgrounds open between late April and mid-June and close in early-to-mid October, with exact 2026 dates in the length table above. Stays are capped (typically around 14 nights across the park), which keeps long-haul RVers from parking for a month. And because the window is rolling, the practical move is to set a reminder for the day your dates become bookable and reserve the moment they open. We've watched renters miss Colter Bay by a single day because they assumed summer sites would linger.

If your dates are already inside the booking window and the in-park sites are gone, don't write off the trip. Check Gros Ventre Campground and Signal Mountain Campground for cancellations, then look at private parks around Jackson as a fallback.
Should you base your RV inside the park or in Jackson?
Base inside the park if your priority is waking up to the Tetons and you're fine with limited hookups; base in Jackson if you want full hookups, easy resupply, and a shorter drive to restaurants and gear shops. Both work — it comes down to whether the scenery or the conveniences matter more for your trip.
Inside the park, the trade is scenery for services. You're minutes from trailheads, lake access, and sunrise on the range, but outside Colter Bay RV Park and Headwaters you're on electric or dry sites with no sewer at your spot. That's an easy trade for a few nights with a rental that has fresh and gray tanks and a dump station on the way out.
Jackson, roughly a half-hour south of the park's southern boundary, flips it. You get full-hookup private parks like the Jackson Hole / Snake River KOA, grocery and outfitter runs, and the option to pick up an RV rental in Jackson close to where you'll camp. Owners around Jackson tell us a lot of their summer renters base in town for the full hookups and supplies, then day-trip into the park — and if driving a big rig into the mountains is the part you're dreading, some local owners will deliver and set up the RV at your campground so you never have to drive it. The whole region's options are on the Wyoming RV rental hub.
Either way, if Grand Teton is the first half of a bigger trip, it pairs naturally with Yellowstone's RV campgrounds an hour north — the two parks share the Rockefeller Parkway and reward a single loop rather than two separate drives.
Key takeaways
- Full hookups in the park mean Colter Bay RV Park — 102 pull-through sites to 45 feet, back-ins to 30 feet, 20/30/50-amp, open May 4–Oct 9, 2026. Headwaters at Flagg Ranch is the full-hookup backup to the north.
- Match the campground to your rig's length. Limits run 25 ft (Lizard Creek), 30 ft (Signal Mountain, Colter Bay Campground), and 45 ft (Gros Ventre, Colter Bay RV Park, Headwaters).
- Jenny Lake is tents-only — no RVs, despite being the campground people try hardest to book.
- Reserve on Recreation.gov the day your window opens. Everything is reservation-only and the full-hookup sites go first.
- Base in the park for scenery, in Jackson for hookups and supplies — and ask about RV delivery if you'd rather not drive the rig.
