With its spectacular Rocky Mountain and prairie landscapes, Wyoming is a glorious destination for an RV vacation. It’s famously the least-populated state
, making Wyoming an ideal place to get away from it all on an RV trip. Fortunately, getting away from it all doesn’t mean going without all the essential services and amenities you need, including those unpleasant-yet-necessary dump stations.
Wyoming has few big cities, but plenty of RV campgrounds with dump stations are available to overnight guests and day-use visitors, too. Adding to the options for RV dump stations in Wyoming are travel plazas, truck stops, rest areas, and municipal facilities. Many are open only in summer, so off-season visitors should do plenty of research before hitting the road.

Private RV Parks in Wyoming
There are close to 300 campgrounds and RV parks
in Wyoming, mostly concentrated around the state’s major tourist attractions, including its national parks, Devils Tower National Monument, and scenic byways. Private RV campgrounds and resorts across Wyoming vary considerably in the amenities they offer, but an on-site dump station is a typical feature. The dump station is nearly always free for registered overnight guests. Some properties will allow non-guests to use their dump stations for a small fee. Policies vary, so always call ahead.
Travel Plazas and Truck Stops
Travel plazas and truck stops are very reliable providers of dump stations in Wyoming, although their locations are limited to major highways. A major bonus of using dump stations at travel plazas and truck stops is the convenience of refueling and stocking up on other supplies, such as propane and groceries, at the same time.
Some names to look for on the road in Wyoming include Pilot Flying J, a comprehensive nationwide travel plaza brand with 10 locations
in the state, and Maverik
, a chain of truck stops across the West that was founded in Wyoming. Its Casper, Laramie, and Green River locations have RV dump stations.
