Wyoming RV Dump Stations | Sani-Dumps.com

Wyoming has several RV dump stations spread across the state. You'll find them at state park campgrounds, national park campgrounds in Yellowstone and Grand Teton, private RV parks along the I-25 and I-80 corridors, and at some travel centers and truck stops. The highest concentration of dump stations is along the interstate highways and near the major gateway towns for Yellowstone, including Cody, Jackson, and Dubois. In more remote areas of the state, dump stations can be 50 to 100 miles apart, so check your route before heading into the backcountry. Many state park dump stations are available to campers as part of their nightly fee, while some also allow day-use dumping for a small fee.

Wyoming has some free dump stations, which accounts for a portion of all stations in the state. That means a portion of dump stations charge a fee. Free options are limited here compared to some western states. Some municipal facilities and a handful of campgrounds offer complimentary dump access, but you'll need to plan around them since they're spread across a large state with significant distances between towns. Most state park dump stations are included with your camping fee but aren't technically free for day-use visitors. Private RV parks along the interstates sometimes offer dump access to non-guests for a fee, typically $5 to $15. Your best bet for truly free dumps is to check town-operated facilities in smaller communities.

Dump station fees in Wyoming range from free to about $15 depending on the facility. State park dump stations are often included with your campsite fee ($17 to $30 per night), though standalone dump use may cost $5 to $10. National park campground dump stations in Yellowstone and Grand Teton are available to registered campers at no extra charge beyond the camping fee. Private RV parks typically charge non-guests $5 to $15 for dump access. Travel centers and truck stops along I-80 and I-25 may offer dump stations for a small fee or free with a fuel purchase. Always confirm pricing before you pull in, because rates can change seasonally and some places only offer dump access during certain months.

Every dump station visit goes smoother with the right gear. Bring disposable gloves (we like the heavy-duty nitrile ones), a clear sewer elbow so you can see when your tanks are running clean, and a dedicated sewer hose that's at least 15 feet long. A hose support or slinky is handy for longer runs between your rig and the dump hole. Keep a bottle of tank treatment on hand to add after you dump. Bring your own fresh water hose for rinsing, and never use your drinking water hose for anything near the dump station. Paper towels or disinfectant wipes for cleanup are a must. In Wyoming specifically, bring something to weight down your sewer hose connection, because the wind can blow loose fittings around in a hurry.

Most dump stations in Wyoming close for the winter, typically from late October through April or May. The harsh winters, with temperatures regularly dropping below zero and heavy snowfall at elevation, make it impractical to keep water-dependent facilities running. Some private RV parks in Cheyenne, Casper, Rawlins, and Rock Springs maintain heated dump stations through the winter months, but options are very limited. Yellowstone's campground dump stations close when the park roads close in early November, and they don't reopen until late April or May. If you're traveling through Wyoming in winter, call ahead to confirm any dump station is actually operational before making a long detour. The few winter-accessible stations tend to be at full-service private RV parks along I-25 and I-80.

Wyoming does not have dump stations at its interstate rest areas. Unlike some states that install sani-dumps at highway rest stops, Wyoming's rest areas only offer restrooms, picnic areas, and pet walking zones. You'll need to plan your dump stops at campgrounds, RV parks, or dedicated dump station facilities in towns along your route. This is especially important to know if you're crossing southern Wyoming on I-80, where the distances between towns with dump stations can be significant. Some rest areas on I-80 and I-25 have potable water, but that's the extent of RV services available. Plan to dump at a campground or RV park in one of the corridor towns like Cheyenne, Laramie, Rawlins, Rock Springs, or Evanston.

Inside Yellowstone, dump stations are available at several campgrounds including Bridge Bay, Canyon Village, Fishing Bridge, Grant Village, and Madison. These are open to registered campers during the park's operating season, roughly late May through early October depending on the campground. Outside the park on the Wyoming side, Cody has several private RV parks with dump access along the road to Yellowstone's East Entrance. The town of Dubois on US-26/287 has options if you're approaching from the southeast via Togwotee Pass. Jackson and the surrounding area near Grand Teton offer multiple dump stations at both park campgrounds and private facilities. West Yellowstone, Montana, just over the state line, is another common dump stop for RVers using Yellowstone's West Entrance. Book campgrounds inside the park early, because a confirmed site guarantees dump access.

Wyoming is one of the best states in the country for boondocking. The Bureau of Land Management administers millions of acres of public land here, especially in the western and central parts of the state. Areas around Lander, Pinedale, the Wind River Range, the Red Desert, and the Bighorn Basin all have extensive BLM land where dispersed camping is free with a 14-day stay limit. You'll need to be fully self-contained since there are no dump stations, water, or hookups on BLM land. The tradeoff is incredible solitude and scenery that you won't find at any paid campground. Cell service can be spotty or nonexistent in remote areas, so download offline maps before heading out. Make sure your tanks are dumped and your fresh water is full before you leave the pavement.

The wind on I-80 across southern Wyoming is genuinely dangerous for RVs, and we're not exaggerating. This corridor, particularly between Rawlins and Evanston, is one of the windiest stretches of interstate in the entire country. Sustained winds of 40 to 50 mph are common, and gusts regularly exceed 60 to 70 mph during storm events. The Wyoming Department of Transportation closes I-80 to light, high-profile vehicles multiple times each year, and these closures can last from a few hours to a full day. If you're towing a travel trailer or fifth wheel, or driving a tall motorhome, take these advisories seriously. Check wyoroad.info or call 511 before heading out. Some RVers choose to cross this stretch only in the early morning when winds tend to be calmer. There are very few alternate routes if I-80 closes.

Yes, several campgrounds inside Yellowstone National Park have dump stations available to registered campers. Bridge Bay, Canyon Village, Fishing Bridge RV Park, Grant Village, and Madison all have dump facilities. These stations are included with your campsite fee, which ranges from $15 to $30 per night depending on the campground. Most Yellowstone campgrounds open between late May and mid-June and close in September or October. Fishing Bridge RV Park is the only campground in Yellowstone with full hookups, including sewer, so you won't need the dump station there. For the other campgrounds, plan to use the dump station when you check out. Lines can get long on busy checkout mornings in July and August, so arriving early at the dump station helps. Reservations are essential during peak summer months.

The sweet spot for RVing in Wyoming is mid-June through mid-September. All campgrounds and dump stations are open during this window, the mountain passes are clear of snow, and daytime temperatures are comfortable in the 70s and low 80s at most elevations. July and August are the warmest months but also the most crowded, especially in and around Yellowstone and Grand Teton. If you can swing it, September is our favorite month to visit. The crowds thin out dramatically after Labor Day, fall colors start popping in the Tetons and Bighorn Mountains, and the weather is still pleasant even though nights get chilly. Avoid planning an RV trip to Wyoming between November and April unless you're experienced with winter RV travel and have a rig set up for cold weather. Many facilities are closed and road conditions can be treacherous.

Wyoming doesn't impose blanket RV size restrictions on its highways, but some roads and routes have practical limitations you should know about. The standard maximum width for RVs on Wyoming highways is 8.5 feet, and combined vehicle length limits are 85 feet. Inside Yellowstone and Grand Teton, certain roads and parking areas have posted vehicle length limits, and some campground loops can only accommodate rigs up to 30 or 40 feet. The Beartooth Highway (US-212) near Yellowstone's Northeast Entrance has steep switchbacks and tight curves that can be challenging for large motorhomes or long trailers. Togwotee Pass on US-26/287 is manageable for most RVs but has some steep grades. Mountain roads and forest service roads off the main highways may not be suitable for rigs over 30 feet. Check specific campground listings for length restrictions before you book, and always verify road conditions on mountain passes.

Propane refills are available in most Wyoming towns of any size, typically at hardware stores, farm supply stores, gas stations, and RV parks. Cheyenne, Casper, Gillette, Sheridan, and Rock Springs all have multiple propane suppliers and RV supply stores. In the Yellowstone area, Jackson and Cody both have well-stocked options. For more specialized RV repairs and parts, your best bets are Cheyenne and Casper, which have the largest populations and the most RV dealerships and service centers. In smaller towns like Thermopolis, Lander, or Powell, you can usually find propane but may struggle to find specific RV parts or service. Carry basic spare parts and tools with you, because the nearest RV service center could be several hours away if something breaks in a remote area. Stock up on supplies in the larger towns whenever you pass through.

Wyoming allows overnight parking at most of its rest areas, but with a 24-hour limit. This makes rest areas a useful option for a quick overnight stop when you're in between campgrounds, especially on long hauls across I-80 or I-25. Rest areas have restrooms and sometimes picnic tables, but there are no dump stations, hookups, or water fills available. You'll be dry camping in a parking lot, so make sure your rig is self-contained. Some rest areas have better overnight spots than others. The ones with pull-through parking and adequate space for RVs tend to fill up on busy summer travel nights. Keep in mind that Wyoming rest areas are not campgrounds, so setting up camp chairs, grills, or awnings is generally frowned upon. Use them for sleeping only, and move on in the morning.

Green River's free 24/7 sanidump on East Flaming Gorge Way is the gold standard. Clean, well-maintained, and handles high volume without backing up. It's perfectly positioned for cross-country travelers between Salt Lake City and Denver. The station operates year-round and doesn't charge a dime.

Yes, but they're only for registered campground guests during your stay. Fishing Bridge RV Park has the most accessible station. If you're just passing through, use dump stations in gateway towns like West Yellowstone, Gardiner, or Jackson before entering the park. Summer waits can hit 30-45 minutes at park facilities.

No. Wyoming rest areas don't have sanitary dump stations. You can park overnight for up to eight hours, but there's no RV waste disposal. Plan your dumps at town facilities or campgrounds. The state maintains clean restrooms at rest areas but nothing for black or gray tank dumping.

Bad enough to flip trailers and fifth wheels when gusts exceed 50 mph. The stretch between Rawlins and Laramie is notorious. WYDOT closes the highway to light and high-profile vehicles during extreme wind events. Check wyoroad.info before traveling. If sustained winds hit 40 mph, consider waiting it out.

Green River, Rock Springs, Cheyenne, and Casper maintain year-round facilities. Most mountain town stations close November through April. Yellowstone's north entrance at Gardiner operates year-round, but park dump stations shut down. Always call ahead in winter -- 'year-round' sometimes means 'weather permitting' in Wyoming.

Jackson has several options including a public station and private campgrounds. Colter Bay inside the park serves registered guests only. The town of Moran just outside the east entrance offers services. Book Grand Teton campsites far in advance -- they fill up within hours of becoming available on recreation.gov six months out.

Yes, but they're spread out. Rock Springs and Pinedale offer services on the southern approach. Once you're north of Pinedale, options thin out until you reach Jackson or Moran. Plan your dump before the final push into the parks. Summer traffic on this route gets heavy with RVs.

The highest-rated is Leigh Creek RV Dump Station with a rating of 4.6/5 stars.
