About Threemile Campground
Just three miles from Yellowstone's East Gate, Threemile Campground offers an intimate escape into Wyoming's wild heart. This secluded haven, exclusively for hard-sided RVs and trailers due to the area's active bear population, provides the perfect basecamp for adventurers seeking tranquility without sacrificing convenience. Modern amenities including bear-proof food lockers, vault toilets, and fresh drinking water ensure a comfortable stay while you immerse yourself in the untamed beauty of the Greater Yellowstone Ecosystem.
Threemile Campground exclusively accommodates hard-sided RVs and camp trailers due to bear activity in the area. It does not allow tent camping, pack animals, or off-road vehicles.

Today, this historic treasure invites visitors to explore its storied halls and discover tales of frontier life through captivating tours. A short drive to Cody reveals the renowned Buffalo Bill Historical Center, where five museums under one roof chronicle the rich tapestry of Yellowstone's past, from Native American heritage to the golden age of Western exploration.

This pristine ecosystem offers front-row seats to nature's daily spectacle, from deer grazing in morning light to the haunting calls of wildlife echoing through twilight shadows.
