Threemile Campground is located just three miles from the east entrance of Yellowstone National Park, and 50 miles from the full service gateway community of Cody, in northwestern Wyoming. The area is an ideal destination for a family getaway, with many opportunities for outdoor recreation. Hard-sided camp trailers and RVs are required. Great opportunities for hiking, fishing, scenic driving and wildlife viewing are available around the campground. The North Fork of the Shoshone River is a popular fly-fishing location for rainbow and Yellowstone cutthroat trout. The nearby Pahaska Trail provides access into the North Absaroka Wilderness Area.
