RV Parks In Yellowstone National Park, Wyoming

For RVers, Fishing Bridge RV Park is the marquee choice because it is the only campground inside Yellowstone with full hookups, with around 310 sites and big-rig pads up to 95 feet on its renovated upper loop. If you can dry-camp, Bridge Bay on Yellowstone Lake, Canyon near the Grand Canyon of the Yellowstone, Grant Village in the south, and Madison on the river all take rigs to 40 feet. Outside the gates, Yellowstone Grizzly RV Park in West Yellowstone is the full-hookup big-rig favorite.

Only one does. Fishing Bridge RV Park is the single campground inside Yellowstone with full hookups, offering 30 and 50 amp electric, water and sewer at the site. Every other in-park campground (Bridge Bay, Canyon, Grant Village, Madison, Mammoth and the smaller loops) is dry camping with no hookups, though most have an RV dump station and potable water fill. If full hookups matter to you, either book Fishing Bridge early or stay at a private gateway park in West Yellowstone, Gardiner or Cody. The good news is that all five reservable in-park campgrounds have dump stations and potable water, so even without a hookup site you can keep your tanks managed for a multi-day stay.

In-park dry-camping sites at places like Bridge Bay, Canyon, Grant Village and Madison generally run in the mid-$30s to mid-$40s per night. Fishing Bridge full-hookup sites are higher, commonly in the $90-plus range because they are the only hookups in the park. Private gateway parks vary widely: a full-hookup big-rig pull-through in West Yellowstone can run roughly $90 a night in peak summer, while simpler sites cost less. Mammoth, the first-come campground, is the budget option at the low end. Remember to factor the park entrance fee on top of any campsite, and note that dry camping trades the nightly hookup premium for generator fuel and propane instead.

As far ahead as you possibly can for summer. Five in-park campgrounds take reservations through Yellowstone National Park Lodges or Recreation.gov, and they fill months in advance for June through August. Fishing Bridge full-hookup is the hardest reservation in the park and should be booked the moment your window opens. Gateway private parks in West Yellowstone and Cody also sell out their big-rig pull-throughs for peak weekends, so lock those in early too. Only Mammoth Campground is first-come, first-served, and even it can fill by midday in peak summer. A good rule of thumb is to treat your campsite reservation as the very first thing you book for a Yellowstone trip, before flights or rental rigs.

September is our favorite window: the crowds thin out, the elk rut kicks in, and the cottonwoods turn gold, but campgrounds and most services are still open early in the month. Summer (June through August) is the surest bet for everything being open, but it is also the most crowded and the hardest to reserve. Late May and early June can be beautiful with lingering snow at elevation. Winter essentially closes the park to RVs, so plan for the May-to-October season. If you want the geyser basins steaming against cold air with the smallest crowds, aim for the first two weeks of June or the last two of September.

Yes, with planning. Fishing Bridge RV Park is the most big-rig friendly choice in the park, with paved upper-loop pull-through and back-in sites ranging up to about 95 feet plus full hookups. Bridge Bay, Canyon, Grant Village and Madison accept rigs up to 40 feet but offer no hookups. Interior park roads are steep, narrow and congested, so a very long rig is happier based at a gateway full-hookup park with 80-foot pull-throughs like Yellowstone Grizzly in West Yellowstone, then day-tripping into the park. Whatever you drive, build in extra travel time, because summer wildlife jams and road construction routinely turn a short hop between basins into an hour behind the wheel.

Inside the park, dispersed boondocking is not allowed, but Mammoth Campground runs first-come, first-served if you want to skip the reservation system. Real free camping is found on the surrounding national forests: the Custer Gallatin and Shoshone National Forests outside the gates have dispersed sites and small forest campgrounds where self-contained rigs can stay. These have no hookups and limited big-rig room, so come fully self-sufficient with water and waste capacity, and respect bear-country food storage everywhere around Yellowstone. Forest campgrounds near the gates fill on summer weekends too, so arrive early in the day if you are counting on a first-come site rather than a reservation.

Dump stations are available at Bridge Bay, Canyon Village, Fishing Bridge, Grant Village and Madison. Since only Fishing Bridge has hookups, most RVers in the park are dry camping and will use these dump stations to empty tanks and the potable water spigots to refill. Plan your loop so you hit one before and after a few days of dry camping. If you want the full rundown on tank service in the area, see our guide to RV dump stations in Yellowstone National Park linked below.

Most campgrounds take RVs, but each has a length limit and a few quirks. Bridge Bay, Canyon, Grant Village and Madison handle rigs up to 40 feet. Fishing Bridge is RV-only and, because of frequent grizzly activity, allows hard-sided units only, no tents or pop-up tent trailers. The smaller, older loops like Mammoth, Indian Creek, Pebble Creek, Tower Fall and Slough Creek tilt toward tents and short trailers, so check the per-site length before booking a larger rig into those. When in doubt, the NPS campground page lists the maximum combined vehicle length for every loop, and it pays to measure your rig plus any toad before you reserve.

Fishing Bridge sits in prime grizzly bear habitat near Yellowstone Lake, so the National Park Service restricts it to completely hard-sided RVs, no tents or tent trailers. All food, coolers, grills, toiletries and pet supplies must stay locked inside your vehicle or RV at all times. This is for your safety and the bears, and it is strictly enforced. The same food-storage discipline applies parkwide, but Fishing Bridge is where the hard-sided rule is absolute, which is part of why it is so popular with RVers.

Yellowstone is fundamentally a May-to-October RV destination. Campgrounds open on a staggered schedule in May, with Fishing Bridge opening around May 8 and the lakeshore campgrounds following mid-month, and most close between mid-September and mid-October as snow returns to the high country. The park sits high, around 7,800 feet at Fishing Bridge, so nights are cold even in midsummer. Winter closes the interior roads and nearly all camping; only the Mammoth area near the North gate stays accessible. Because openings shift year to year with snowpack, always confirm a campground is actually open for your dates on the official park site before you build a route around it.

It depends on what you value. Staying inside the park puts you closest to the geysers and wildlife at dawn and dusk, but only Fishing Bridge has hookups and reservations are brutal. Gateway towns trade a little drive time for comfort: West Yellowstone, Montana sits three blocks from the West gate with full-hookup big-rig parks, Gardiner anchors the North gate, and Cody, Wyoming guards the scenic East entrance with full-hookup parks in the Wapiti Valley. Many RVers split the difference and base in a gateway town with power and showers.

Plan for very limited connectivity. Cell coverage inside Yellowstone is spotty to nonexistent across most of the interior, with usable signal mostly near developed areas like Old Faithful, Canyon, Grant Village and Mammoth. Only Fishing Bridge offers electrical hookups, so running an RV off-grid for days means managing battery, solar and generator hours within quiet-hour rules. If you need to stay connected for work, base at a gateway private park in West Yellowstone or Cody where Wi-Fi and cell service are far more reliable, and day-trip into the park.
