RV Dump Stations In Sheridan, Wyoming

The best option is the free RV dump station at the Sheridan Information Center rest area on I-90 near mile marker 23. It has two bays laid out so you can pull through from either side, plus restrooms and covered picnic tables. It’s a day-use dump signed no overnight camping, so plan to service the rig and move on. If you need to dump while camped, the Sheridan / Big Horn Mountains KOA and other private RV parks in town have their own dump stations for guests, so between the rest area and the parks you’re well covered either passing through or staying overnight.

Yes. The Sheridan Information Center rest area on I-90 at mile marker 23 has a genuinely free two-bay RV dump station, which is one of the better free dumps in this part of Wyoming. It’s bidirectional and easy to reach from either direction of the Interstate, with restrooms and picnic areas alongside. The only catch is that it’s day-use only and signed no overnight camping, so use it to service the rig as you pass through rather than as a place to sleep. If you want free water and a free dump in one stop, this is your spot.

The most reliable free option is the Sheridan Walmart Supercenter, which generally tolerates overnight parking for self-contained rigs, though that’s always at the manager’s discretion, so step inside and ask. The I-90 Information Center rest area is signed no overnight camping, so don’t count on it for sleeping even though its dump station is free. For a free night in nature, head up US-14 into Bighorn National Forest, where dispersed camping is allowed on many forest roads subject to USFS stay limits and fire rules. Just be ready for cold mountain nights and a steep climb to get there.

Interstate 90 runs straight through Sheridan with easy big-rig exits for fuel, groceries and RV parks, plus the Information Center dump station near mile marker 23. US-87 parallels I-90 as a slower valley route. The scenic one is US-14, the Bighorn Scenic Byway, which climbs west into the mountains from Ranchester and Dayton. The Interstate is genuinely easy for any size rig, but US-14 is a serious mountain grade with steep climbs, switchbacks and late-lying snow, so plan that one carefully or drive it in your tow vehicle instead of the motorhome.

It can be, but go in with eyes open. The Bighorn Scenic Byway (US-14) is paved and open to RVs, and plenty drive it every summer, but it’s a genuine mountain road with sustained steep grades, switchbacks and major elevation gain over the Bighorns. Underpowered rigs will crawl on the climbs and can overheat brakes on the descents. Know your engine and braking, gear down early, and use pullouts to let faster traffic by. If you’re towing something long or you’re not confident, the smart move is to leave the RV at your park and drive the byway in the tow vehicle.

June through September is the comfortable window, with warm days, cool nights and the mountain roads open. July and August are the most reliable for weather but also the busiest, so book private parks ahead on weekends. Early September is a sweet spot: crisp, dry, quieter and cheaper, with the byway still open. Spring is wet and the high passes stay snowbound into early summer, while winter is cold, snowy and windy with US-14 subject to closure. Whenever you come, pack layers, because the elevation keeps nights cool even in midsummer.

Sheridan has a semi-arid steppe climate with short, hot, dry summers and cold, snowy, windy winters. July highs run around 87F with cool nights, and afternoon thunderstorms are common up in the mountains. Winter highs sit between the mid-teens and about 30F from December through February, with snow from October into May and roughly 46 inches a year. Spring is the wettest stretch, April through June, with snow lingering in the high country well into summer. Wind is a near-constant year-round, so it pays to secure your awning and watch I-90 wind advisories.

Sheridan covers the essentials well. Propane is available in town and at the area RV parks. Fuel, including truck-stop fuel, is easy right at the I-90 exits, and prices are usually competitive with anywhere in northern Wyoming. RV service and repair can be found locally for routine needs. Potable water is available at the RV parks and the Information Center rest area. Full grocery and big-box stores sit near the Interstate, which makes Sheridan a smart place to top off fuel, water and food before you head up into the Bighorns or continue across the plains, where services thin out fast.

For full hookups, the Sheridan / Big Horn Mountains KOA and the newer, big-rig-friendly Station RV Park are the go-to private parks, both with easy I-90 access, and Wyoming RV Park is another local option. For a mountain experience, Bighorn National Forest has developed campgrounds up US-14 like Sibley Lake, Prune Creek and Tie Flume, many reservable on Recreation.gov, though they sit at high elevation with no hookups and a short season. Between full-service parks in town and rustic forest campgrounds up the byway, you can pick anything from pull-through convenience to quiet alpine camping.

Yes. Bighorn National Forest surrounds the high country west of town and allows dispersed camping on many forest roads off US-14 and US-14A, which is a good free option if the private parks are full or you just want quiet. Standard USFS rules apply: observe posted stay limits (often up to 14 days), use existing sites, pack out everything, and check current fire restrictions before lighting anything. The catch is elevation and access. Those roads climb high, so nights are cold even in summer and the grade to get up there is steep, so make sure your rig is up to the climb.

Quite a lot for a town this size. Trail End State Historic Site preserves the 1913 Kendrick Mansion, a Flemish Revival home and museum overlooking town. King’s Saddlery is a renowned saddle maker with a large Western and cowboy-gear museum, and the historic Mint Bar and the Sheridan Inn, where Buffalo Bill once auditioned Wild West Show acts, anchor a downtown with real character. Add local shops, restaurants and easy access to trout streams and the byway, and Sheridan makes a comfortable base rather than just a fuel stop on I-90.

The Bighorn Scenic Byway (US-14) starts climbing about 15 miles northwest of Sheridan near Ranchester and Dayton, so you’re at the base of the mountains within a short drive. Shell Falls, the 120-foot cascade with interpretive trails, sits roughly 50 miles west along the byway, deep into Bighorn National Forest, making it a solid half-day round trip. Because the drive is a serious mountain grade, many RVers base in Sheridan and run the byway in their tow vehicle, which lets you enjoy the switchbacks, Sibley Lake and Shell Falls without hauling the rig over the pass.
