RV Camping Yellowstone National Park: Sites, Hookups, Fees, and Insider Tips for 2026

Let me be straight with you up front, because nobody told me this the first time and I paid for it. RV camping in and around Yellowstone National Park is some of the best you will ever do, but the park does not make it easy on a rig.

It is enormous, the internal roads are slow and twisty, and a quick hop between campgrounds can eat half your day. The season is short and snow shows up early and late, so realistically you are looking at roughly May through September depending on the campground.

And here is the big one: there is exactly one campground inside the park with full hookups. One. Everything else is dry camping with a dump station and water somewhere nearby.

So you plan ahead or you sleep in a parking lot in West Yellowstone wondering where it all went wrong.

The popular in park campgrounds book months out. You are camping in serious bear country, so food storage is not a suggestion, it is the rule. You are sitting at altitude, which means generators wheeze a little and your fridge works harder. None of this is a dealbreaker. It just rewards people who do their homework, which is why you are here.

This guide breaks it into three tiers: in park campgrounds, nearby private full hookup parks in the gateway towns, and free dispersed camping on the surrounding national forest.

Most guides organize purely by entrance and skip the things that actually trip RVers up, like per site length limits, dump station locations, bear box rules, generator hours, and where you can legally boondock for free. 

Quick Answer

For RV camping in Yellowstone in 2026 you have three real options. In park campgrounds are cheapest on location (roughly $20 to $94 a night), but only Fishing Bridge RV Park has full hookups and the rest are dry camping with dump stations.

Private full hookup RV parks in gateway towns like West Yellowstone and Gardiner are full service and easy but more expensive.

Free dispersed camping on the surrounding national forest has no services and suits smaller rigs best. Best season is roughly June through September.

The main catch is that hookups are almost nonexistent inside the park, length limits run tight at the smaller campgrounds, and the good spots book months in advance. Per the National Park Service, reservations are required for park campgrounds from April 17 to October 15, 2026.

Quick Definitions (So the Rest of This Makes Sense)

Full hookup: a site with electric, water, and sewer at the pad. Inside Yellowstone only Fishing Bridge RV Park has this.

Partial hookup: usually electric and water, no sewer at the site.

Dry camping (no hookups): a site with no electric, water, or sewer. You run on your own battery, water tank, and waste tanks. Most in park campgrounds are dry.

Dispersed camping (boondocking): free camping outside developed campgrounds, generally on national forest land, with no services at all.

Dump station: a place to empty your gray and black waste tanks. Several in park campgrounds have one even though the sites are dry.

Potable water: drinking water you can fill your fresh tank from.

First come, first served (FCFS): no reservation, you take an open site when you arrive.

Reservation: a site you book ahead through the concessioner or recreation.gov.

Hard sided vs soft sided: in prime bear habitat like Fishing Bridge, only fully hard sided units are allowed. No tents, no pop up tent campers, no soft canvas tent style fold outs.

Rules and What to Know First

A few hard truths before you commit to anything.

Book early. For the 2026 season, the five concessioner campgrounds (Bridge Bay, Canyon, Grant Village, Madison, and Fishing Bridge RV Park) are reserved through Yellowstone National Park Lodges, the park concessioner. The five recreation.gov campgrounds (Mammoth, Indian Creek, Lewis Lake, Slough Creek, Tower Fall) are booked on recreation.gov. The National Park Service states reservations are required from April 17 to October 15, 2026. Heads up: starting with the 2027 season, the concessioner has announced that all five of its campgrounds move to recreation.gov too, opening roughly six months in advance.

Only Fishing Bridge RV Park has full hookups. Water, sewer, and electric (50 amp service per NPS). Every other campground in the park is dry camping. Plan your water and waste around that.

Fishing Bridge is hard sided units only. NPS states it is for completely hard sided units only, no tents or tent campers, because it sits in prime bear habitat. If your rig has soft canvas, you cannot stay there.

Bear food storage is mandatory. Per NPS, all food and related items (beverages, cooking utensils, stoves, pet food, coolers, ice chests, and water jugs) must be locked inside a hard sided vehicle or stored in a provided food storage box unless in immediate use. Trash goes in the bear proof cans. Do not leave a cooler out, ever.

Generator hours and quiet hours apply. Generators are allowed only during posted hours at the campgrounds that permit them, and quiet hours are enforced. Confirm the current hours and decibel limit for your campground at booking.

2026 has closures. Pebble Creek and Norris are both closed for the 2026 season (Pebble Creek remains closed for flood recovery after the 2022 floods). Mammoth is the only campground open year round.

RV length limits are real and vary a lot. Some campgrounds top out around 25 to 40 feet, others handle 60 plus. Check your specific site before booking, not just the campground.

To confirm the current details yourself, check: Yellowstone camping overview (NPS),  and the concessioner camping page.

The Campgrounds

Tier 1: In Park Campgrounds

Fishing Bridge RV Park, near Yellowstone Lake and the mouth of the Yellowstone River. Run by the concessioner, Yellowstone National Park Lodges. This is the only full hookup option inside the park, full stop, which is exactly why people fight for it. It was recently renovated to 310 sites. Rig fit: max RV length up to 95 feet per NPS; full hookups with 50 amp service, water, and sewer; hard sided units only; cell signal is spotty so do not count on it. The nightly fee is $94 plus taxes per NPS. Insider tip: this is the only spot inside the park where you can run climate control all night without a generator, so if you want a comfortable base camp and you can snag it, book it the instant your window opens. 2026 season runs May 8 to October 17 per NPS.

Bridge Bay Campground, on Yellowstone Lake near the marina. Concessioner run. Big campground (431 sites), central location, good launching point for the lake and the southern loop. Rig fit: max RV length 60 feet per NPS; no hookups; dump station on site; cell signal weak. Fee $38 plus taxes per NPS. Insider tip: it is one of the larger campgrounds so it feels less like a sardine can than its size suggests, and the lake breeze keeps bugs down compared to the forest sites. 2026 season is May 15 to September 13 per NPS.

Madison Campground, near the west entrance where the Gibbon and Firehole rivers meet. Concessioner run. Closest in park campground to West Yellowstone and a great base for the geyser basins (276 sites). Rig fit: max RV length 60 feet per NPS; no hookups; dump station on site; cell signal is poor. Fee $38 plus taxes per NPS. Insider tip: the bison wander right through this one in the evenings, so keep your distance and your dog leashed and inside. It is one of the longer running seasons, May 1 to October 17 per NPS.

Grant Village Campground, on the southwest shore of Yellowstone Lake near the south entrance. Concessioner run (429 sites). Handy if you are coming up from Grand Teton. Rig fit: max RV length 50 feet per NPS; no hookups; dump station on site; weak cell. Fee $45 plus taxes per NPS. Insider tip: it opens later than most, so do not plan an early June trip around it. 2026 season is June 26 to September 26 per NPS.

Canyon Campground, near the Grand Canyon of the Yellowstone in the center of the park. Concessioner run (272 sites). Central, which saves you those long internal drives. Rig fit: max RV length 40 feet per NPS; no hookups; dump station on site; spotty cell. Fee $45 plus taxes per NPS. Insider tip: Canyon Village right next door has a store, showers, and laundry, so this is the most stocked up feeling base in the interior. 2026 season is May 29 to September 19 per NPS.

Recreation.gov campgrounds: Mammoth, Indian Creek, Lewis Lake, Slough Creek, Tower Fall. These NPS campgrounds reserve through recreation.gov. They are smaller, quieter, and cheaper ($20 to $25 per NPS), but the length limits get tight fast. Rig fit per NPS: Mammoth fits up to 40 feet at most sites with a few up to 75 feet (it is the only year round campground; first come, first served October 15 to April 1); Indian Creek up to 35 feet (June 12 to September 14); Lewis Lake up to 25 feet, small rigs only (June 15 to October 11); Slough Creek up to roughly 30 feet (June 15 to October 12); Tower Fall up to roughly 30 feet (May 22 to September 27). Not every one of these has a dump station or potable water, so plan to fill and dump elsewhere. Cell signal is mostly dead. Insider tip: Slough Creek in the Lamar Valley is wolf and grizzly country and one of the most magical spots in the park, but the access road is rough washboard and the campground has only 16 sites, so it favors smaller, capable rigs. This is exactly the kind of dry, no hookup loop where a self contained trailer that makes its own power, like the Evotrex-PG5, earns its keep, since you are not relying on a pedestal that is not there. Reminder: Pebble Creek and Norris are closed for 2026.

To confirm rig fit and dates yourself, check the NPS campgrounds page, and the recreation.gov Yellowstone gateway.

Tier 2: Nearby Private RV Parks and Gateway Towns

These are your full service options in the gateway towns of West Yellowstone, Gardiner, Cooke City, and Cody. You give up being inside the park, but you gain electric, water, sewer, laundry, and showers.

Yellowstone Grizzly RV Park, West Yellowstone, Montana. Private RV park about four miles from the west entrance. This is the easy button: full service near town with restaurants and a store close by. Rig fit: big rig friendly pull throughs that handle the largest RVs; full hookups; town cell coverage is solid. Insider tip: because it is in town you can leave the rig plugged in and drive your tow vehicle into the park each day, which is far saner than dragging 40 feet of trailer through Yellowstone traffic.

Sun Outdoors Yellowstone North, Gardiner, Montana. Private RV resort about 0.6 miles from the north entrance and the Roosevelt Arch. Rig fit: deluxe full hookup sites; paved town access; good cell in town. Insider tip: the north entrance road through Lamar Valley is the best wildlife drive in the park, so basing in Gardiner puts you closest to the wolves and bears at dawn. The north entrance at Gardiner is the only entrance open year round.

Yellowstone Valley Inn and RV Park, Wapiti Valley between Cody, Wyoming and the east entrance. Private RV park with sites along the river in a canyon. Rig fit: full hookup sites with electric, water, and sewer; paved highway access; cell is patchy in the canyon. Insider tip: the east entrance road over Sylvan Pass is a long, climbing drive, so do not underestimate the distance from Cody to Old Faithful. This is more of a see the east side and Lake area base.

For the northeast entrance (Cooke City): Colter Campground on the Custer Gallatin National Forest near Cooke City is a developed forest campground that suits smaller rigs and puts you right at the quiet Lamar Valley side. Confirm length limits and season directly before relying on it.

Tier 3: Free Dispersed and Boondocking on Adjacent National Forest

A quick rule for all of it: dispersed camping on these forests is generally free, the common limit is 14 days within a 30 day period, and you must stay off trailheads and developed sites. Always check the Motor Vehicle Use Map (MVUM) for legal spots, and call the local ranger district if you are unsure about road conditions or current restrictions. The three forests that ring Yellowstone are Custer Gallatin (north and west), Shoshone (east), and Caribou Targhee (south).

Taylor Fork dispersed area, Custer Gallatin National Forest, along the Gallatin River corridor (Highway 191) northwest of the park. Forest dispersed, roughly 20 sites strung along the river. Rig fit: smaller to mid size rigs do best; gravel forest road access that can get rough; no hookups and no services at all; nearest dump and water is back in West Yellowstone or toward Bozeman; cell signal mostly dead. Insider tip: the Highway 191 corridor itself is technically a sliver of the park with no entrance station, so you can stage here and slide in without a gate line. Pack out everything.

Grassy Lake Road dispersed corridor, Caribou Targhee National Forest, south of Yellowstone toward Grand Teton near Flagg Ranch. Forest dispersed, with miles of pullouts. Rig fit: the first few areas suit small RVs and trailers up to roughly 24 feet; gravel road that degrades the farther you go; no hookups, no services; nearest dump and water is back toward Flagg Ranch or the gateway towns; cell signal dead. Insider tip: this corridor links the south side of Yellowstone to the Tetons, so it is a killer free base if you are doing both parks. The closer pullouts fill first on weekends, so arrive early in the day. This is classic off grid territory where a rig that carries its own lithium battery bank, solar, and an onboard gasoline generator, like the Evotrex-PG5, lets you stay out longer without crawling back to town for shore power.

Forest Road 3243 dispersed area, Custer Gallatin National Forest, near Gardiner just past Eagle Creek Campground. Forest dispersed, free sites close to the north entrance. Rig fit: smaller rigs and capable trailers; gravel road access, check conditions; no hookups or services; dump and water available in Gardiner; cell can reach near town then drops. Insider tip: being minutes from Gardiner means you get free camping with a quick run to town for fuel, water, and a shower, the best of both worlds if your rig handles the road.

To confirm forest rules and roads yourself, check the Custer Gallatin National Forest; Shoshone National Forest; Caribou Targhee National Forest.
