RV Dump Stations In Riverton, Wyoming

Riverton has several dump options in and around town. The most reliable in-town stop is the Wind River RV Park at 1618 E Park Ave, next to the Wind River Casino, which has a dump station along with big-rig hookups. About 15 minutes west, JMA Campground (Jim Moss Arena) offers dumping for around $10. As the largest town in the Wind River Basin, Riverton is the regional service hub, so it is the logical place to empty tanks before heading up into the mountains or out to Dubois, where services thin out considerably.

Availability shifts, so check the current listings for the some free options showing right now. In general the campground stations carry a modest fee if you are not a registered guest, with JMA Campground running about $10 for a dump. If you are staying overnight at the Wind River RV Park or JMA, dumping is typically included in your site fee, so plan your dump around your camping night rather than paying twice. Because Riverton is the basin service hub, it is worth doing a full dump-and-fill here before heading into the higher country where paid or free options are scarce.

The dump points around Riverton generally offer non-potable water for flushing, while potable water comes from the fill stations at the RV parks when you have a hookup site. The Wind River RV Park provides drinking water at its sites, so you can dump and fill fresh in one stop as a guest. As always, keep your potable and flush hoses clearly separated and color coded to avoid any mix-up. Since services get sparse toward Dubois and the Wind River Range, top off your fresh tank in Riverton before you leave town, and do not count on potable water at every dump point.

Riverton sits at the junction of US-26 and WY-789 in the Wind River Basin, with WY-135 running south and US-26/US-287 heading northwest toward Dubois and Jackson. There is no nearby interstate; I-80 is about 120 miles south and I-25 is roughly 120 miles east at Casper, so Riverton functions as a central Wyoming hub. None of the local routes carry RV-specific restrictions, though the Wind River Canyon drive north toward Thermopolis has tunnels, so know your clearances. The roads are comfortable two-lanes for big rigs, but plan fuel stops, since towns are far apart out here.

Yes. There is no blanket overnight-parking ban, and Riverton has good options. The Wind River RV Park next to the casino is the main full-hookup choice, and the Wind River Casino itself allows RV parking. JMA Campground about 15 minutes west is another option with hookups and a dump station. For a quick overnight, the casino lot is convenient, but for comfort and services the RV park is the better bet. Riverton is the largest town in the basin, so unlike smaller Wyoming towns it has the room and the services to handle rigs easily.

May through September is the prime window, with late spring and early fall the most comfortable. Summers are warm, dry, and mostly clear, with highs in the upper 80s and cool nights, ideal for the Wind River Range, Boysen Reservoir, and the canyon drive. Spring warms steadily and stays quiet, while fall brings crisp air and gold cottonwoods along the rivers. Winter is cold, snowy, and windy, with US-26 and WY-789 subject to ice and blowing snow, so it works mainly as a service stop rather than a base for exploring the high country.

Yes. The Wind River RV Park at 1618 E Park Ave is a big-rig park with full hookups up to 100-amp service across 60 sites, 38 of them pull-through, plus laundry, showers, WiFi, and a dump station, all right next to the Wind River Casino. JMA Campground west of town offers 30/50-amp RV sites with WiFi, fire pits, showers, and a dump station for about $10. For state-park camping, Boysen State Park north of town and Sinks Canyon near Lander offer basic and electric sites without full hookups. Any of these lets you dump, fill, and settle into the Wind River country.

The Wind River Canyon Scenic Byway begins north of Riverton on the drive toward Thermopolis, past Boysen Reservoir, and is one of the most dramatic road segments in central Wyoming, with canyon walls exposing nearly three billion years of geology. Sinks Canyon State Park lies about 30 miles southwest near Lander, where the Popo Agie River vanishes into a limestone cavern and reappears downstream. Both make excellent day trips from a Riverton base. The canyon drive has tunnels, so mind your clearances, and Sinks Canyon has a lovely campground if you want to overnight closer to the mountains.

Riverton sits at about 4,900 feet in the Wind River Basin, with warm, dry, mostly clear summers and cold, snowy, windy winters. Summer highs reach the upper 80s and top 90 about three dozen days a year, with cool nights and low humidity that keep the heat comfortable. Winters bring highs around freezing, lows in the teens, and roughly 46 inches of snow a year, with wind a constant on the high plains. Spring and fall are cool and changeable but often the most pleasant. Carry layers year round, and in winter watch the highways for ice and blowing snow.

Yes. Riverton is the largest town in the Wind River Basin and the regional service hub, with full grocery shopping, fuel and hardware outlets that sell propane, and local RV service. For that reason it is the smart place to provision before heading into the thinner country toward Dubois, Sinks Canyon, or the Wind River Range, where stores and services are few and far between. We recommend topping off propane, groceries, fuel, and fresh water here before you leave town. The fuel stations along US-26 and WY-789 have room for big rigs to maneuver, so filling up is easy.

Yes, if you are self-contained. The surrounding Wind River country has extensive BLM and national-forest land with dispersed camping, including open country southeast toward the Castle Gardens petroglyph site and up in the Wind River Range. There is no free camping right in town, so plan to drive out a bit. Always follow posted stay limits and pack out everything, and remember you will still need a dump plan since dispersed sites have no services. The Wind River RV Park in town pairs well with a boondocking stint, giving you a dependable place to dump and fill on your way in or out.

The Wind River Canyon Scenic Byway north toward Thermopolis is the standout, a dramatic drive along the river past Boysen Reservoir through billions of years of exposed rock. Sinks Canyon State Park near Lander, where the river disappears underground, is a close second. In town, the Wind River Heritage Center tells the shared story of the Eastern Shoshone, Northern Arapaho, and settlers, and Fort Washakie on the reservation holds the graves of Chief Washakie and, by legend, Sacajawea. Add Boysen Reservoir for boating and fishing, and Riverton earns a multi-night stay as a Wind River Basin base.

It varies. The state-park campgrounds at Boysen and Sinks Canyon are seasonal and close for winter, and the private parks run largely on the travel season, though the Wind River RV Park in town tends to stay open longer given its casino-adjacent location and full services. Because winters here are cold and snowy, water systems at some sites winterize, so dumping and fresh-water fill can be limited in the off-season. If you are traveling in winter, call ahead before counting on any campground dump, and default to the in-town RV park, which is the most dependable cold-season option in the basin.

We think it is the natural one. As the largest town in the Wind River Basin, Riverton has full services, good RV parks, and a central location that puts the Wind River Canyon, Sinks Canyon, Boysen Reservoir, Fort Washakie, and the eastern Wind River Range all within an easy drive. It also sits on the route between Casper and Jackson, making it a logical stop on a bigger Wyoming loop. Set up at the Wind River RV Park, dump and fill on arrival, provision for the thinner country ahead, and use Riverton as a comfortable, well-supplied hub for the whole region.
