RV Dump Stations In West Yellowstone, Montana

We count several dump stations in and around West Yellowstone. The most dependable in-town options are Yellowstone Grizzly RV Park at 210 Electric Street and Buffalo Run RV Park & Campground, both built for RVs with easy pull-through dump access. There are also two three-lane dump stations inside Yellowstone at Madison Campground, about 14 miles east on the park road, though those require a paid park entrance. A gas station to the south near Macks Inn offers a basic dump too. Most of the local stations are seasonal, so always have a backup in mind during spring and late fall when an early storm can shut things down.

Mostly no. The in-town stations charge a fee, typically in the $5 to $30 range depending on whether you are also filling water or using a private RV park. Buffalo Run lets registered guests dump for free, which is the closest thing to a free option in town. The dump stations inside Yellowstone at Madison are included with your park entrance, but you still have to pay to get into the park. Budget for a paid dump here rather than expecting a free municipal site.

Your choices shrink to almost nothing once the snow flies. Most in-town stations and the forest campgrounds close from roughly mid-October through April, and the West Entrance road into Yellowstone shuts to wheeled vehicles for oversnow travel. Buffalo Run RV Park & Campground is the one place that advertises year-round dumping and water. If you are RVing the area in winter, call ahead to confirm it is open and plan your tank management around that single reliable stop. It is also worth carrying extra holding capacity and arriving with empty tanks, because once the seasonal stations close there is no easy fallback for many miles in any direction.

Yes. Madison Campground, about 14 miles east of the West Entrance on the park road, has two dump stations with three lanes each, plus potable water and a non-potable rinse spigot. It is the handiest in-park option if you are exiting the west side after a stay. The catch is you need to be inside Yellowstone, so factor in a paid entrance pass. If you are already touring the park, timing your dump at Madison on the way out saves a separate trip into town.

Potable water is available at Yellowstone Grizzly RV Park and Buffalo Run, usually bundled with a dump or a stay. Inside the park, Madison Campground offers potable fill alongside its dump stations. The gas station near Macks Inn to the south has rinse water but treat that as non-potable. Because the town sits at high elevation with hard freezes possible even in summer, fill up during the warm part of the day and keep your hose drained so it does not freeze overnight in shoulder season.

Plan on roughly $5 to $30. A standalone dump at a gas station runs around $5, while a full-service stop at a private RV park with water included is closer to $20 to $30. Inside Yellowstone the dump is part of your campground or day-use experience, but the park entrance fee still applies. There is no free municipal dump in West Yellowstone, so the cheapest reliable route is dumping as a registered guest where you are already staying. If you only need to empty tanks and not fill water, the gas-station option is usually the lowest-cost stop, while the private parks bundle dump, water and trash into one fee.

Yellowstone Grizzly RV Park is the most central, with full hookups, a dump station and potable water from about May 1 to October 15. Buffalo Run RV Park & Campground is the year-round standby and the friendliest on dump fees for guests. If you prefer public land, the Custer Gallatin National Forest campgrounds like Bakers Hole sit just north on the Madison River, though they have limited or no hookups and no on-site dump. For full service, the private parks are your best bet.

Yes, in the surrounding Custer Gallatin National Forest. Dispersed sites toward Hebgen Lake and along the forest roads northwest of town are free with no services, so come self-contained and plan a dump stop in town before or after. Developed Forest Service campgrounds like Bakers Hole, Lonesomehurst and Rainbow Point offer a middle ground with fees but more room for rigs. None of the free options have a dump station, so manage your tanks accordingly and do not count on emptying them out on the forest.

US-191 runs north through Gallatin Canyon to Bozeman and I-90, and it stays open year round, though it is shaded and ices early in the canyon. US-20 heads southwest toward Idaho Falls and is the easier winter approach from the south. US-287 connects northwest toward Ennis. All three handle RVs fine in summer; the main thing to respect is the long climb and descent on US-191, where gearing down beats riding the brakes from 6,700 feet down to the valley. In winter, US-20 from Idaho Falls and US-191 from Bozeman are the routes that stay maintained, so plan your approach around the season and check road reports before you roll.

Most West Yellowstone dump stations run from roughly May 1 to mid-October, tracking the snow-free season and the park calendar. Yellowstone Grizzly RV Park lists about May 1 to October 15. Gas-station and forest options can open later and close earlier depending on weather. Buffalo Run is the exception that stays open year round. In spring and late fall, call ahead before you rely on any single station, because an early or late storm at 6,660 feet can shut things down on short notice.

Yes. The private RV parks in town, including Yellowstone Grizzly and Buffalo Run, are built for big rigs and have pull-through access to their dump lanes. Inside Yellowstone, the Madison dump stations have three lanes each and handle large motorhomes and fifth-wheels. The tighter spots are the older forest campgrounds, where sites and turns can be small for 35-foot-plus rigs. If you are in a big coach, stick to the in-town parks or Madison for dumping and scout forest campgrounds before committing.

You are at the doorstep of Yellowstone, so the geyser basins and Old Faithful are the headliners through the West Entrance. In town, the Grizzly & Wolf Discovery Center shows live grizzlies and wolves year round. Hebgen Lake, about 20 minutes northwest, is a Montana stillwater trout favorite for fishing and paddling. A bit farther, Earthquake (Quake) Lake tells the story of the 1959 quake and landslide, with a visitor center open Memorial Day through September. It is an easy place to turn a dump stop into a few days.

Almost always, yes. West Yellowstone is the last cluster of reliable dump stations for a good stretch in every direction, especially heading into the park or out across the forest. Down US-191 and US-20 the options thin out and many are seasonal. Top off fresh water and empty your tanks while you are in town, particularly if you are about to spend days inside Yellowstone where in-park dumping is limited to a few campgrounds. A little planning here saves a long backtrack later.
