Quick Overview

Cody has several RV dump stations in the area, with some offering free access to travelers in this gateway community to Yellowstone National Park's east entrance. This Park County city of about 10,000 sits at the junction of Highways 14, 16, and 20 in the Bighorn Basin of northwestern Wyoming, named after legendary frontiersman Buffalo Bill Cody who founded the town in 1896. RV dump station access near Cody is important for the thousands of RVers who pass through each summer heading to and from Yellowstone, making reliable sani-dump facilities essential infrastructure for this tourism-dependent community. The Buffalo Bill Center of the West, one of the premier museums in the American West, anchors the town's cultural offerings with five museums covering western art, natural history, Plains Indian culture, firearms, and Buffalo Bill's own legacy. The Shoshone River runs through town on its way to Buffalo Bill Reservoir, and the scenic North Fork Highway heading west toward Yellowstone passes through some of the most dramatic mountain scenery in Wyoming. The Wapiti Valley between Cody and Yellowstone is lined with guest ranches, lodges, and campgrounds that have been hosting western visitors for over a century. Cody's nightly rodeo runs throughout summer, the Cody Stampede Fourth of July celebration is one of the biggest rodeo events in the Rocky Mountain region, and the overall western atmosphere of this town feels authentically earned rather than commercially manufactured for tourists. The town's position as the primary eastern gateway means that RV traffic peaks from late June through August when tens of thousands of visitors stream through on their way to Yellowstone's wonders, making dump station planning an important part of any Cody visit during the busy summer travel season.

Last summer we have a very nice stay during our holiday. The ride to the rodeo was a very fun thing to do. The rv sites had a nice terrace so we had a superb experience overall.

Dump your tanks before heading into Yellowstone -- facilities inside the park can have long waits during peak season, and having clean tanks gives you more flexibility for park camping. The Buffalo Bill Center of the West deserves at least a half-day visit and is one of the best museum complexes in the western United States. The Cody Nite Rodeo runs every evening from June through August and is genuine western entertainment at reasonable prices. The scenic drive west on Highway 14/16/20 through the Wapiti Valley is stunning with canyon walls, river views, and the dramatic Absaroka Range rising on both sides. Fill up on fuel and water in Cody before heading to Yellowstone as prices inside the park are significantly higher. The Irma Hotel on Sheridan Avenue, built by Buffalo Bill himself in 1902, has an ornate cherrywood bar worth seeing even if you're just stopping in for a drink.
