304 Wyoming RV Dump Stations | Sani-Dumps.com

Sanidumps lists {{stationCount}} dump stations across Wyoming. The highest concentration is near Yellowstone and Grand Teton national parks, with facilities in gateway towns and inside the parks. I-80 across southern Wyoming and I-25 through the center have reasonable coverage. Remote areas between major routes can have gaps of 80-100 miles.

Currently {{freeCount}} stations in Wyoming are listed as free. Most facilities charge a fee. National park campgrounds include dump access with camping fees. Some smaller towns and municipal facilities offer low-cost dump access. Plan your dump stops in advance, especially when traveling the remote secondary highways.

Yes, Yellowstone's main roads accommodate RVs of all sizes. The Grand Loop Road handles big rigs, though some parking areas are tight for rigs over 40 feet. Several campgrounds accept large RVs -- Bridge Bay and Fishing Bridge are best for the biggest rigs. Side roads to some trailheads may have length restrictions. Construction delays are common in summer, so carry patience and extra fuel.

September is the sweet spot -- warm days, cool nights, fall color, elk rut in the Tetons, and significantly fewer visitors than July and August. June through August is peak season with full campgrounds and the best weather. Late May and early October bookend the season with good conditions but increasing cold. Winter RV travel is extremely limited outside the southern I-80 corridor.

Wyoming wind is a serious safety concern. I-80 across the southern tier regularly sees sustained winds over 40 mph with gusts exceeding 60. High-profile RVs get blown off the road every year. Check WYDOT wind advisories before every travel day, and don't push through closures. The basins and open plains are worst -- mountain valleys and the park corridors are generally more sheltered.

Yes, Colter Bay and Gros Ventre campgrounds in Grand Teton have dump stations. Colter Bay also has an RV park with hookups. The park entrance fee is $35 per vehicle for 7 days. Jackson and the communities along US-89 and US-191 north of town have additional dump facilities. The park is less congested than Yellowstone and easier to navigate in large rigs.

Most Yellowstone campgrounds now require reservations through Recreation.gov, and popular sites book up months in advance. A few campgrounds operate on a first-come, first-served basis. Summer weekends are the hardest to secure. Check the park website for current reservation policies, as the system has been evolving. West Yellowstone and Cody have overflow options when park campgrounds fill.

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 Independence Rock State Historic Site with a rating of 4.7/5 stars.
