About
Greenough Lake Campground is located 12 miles south of Red Lodge, Montana, just off the scenic Beartooth Highway in the Custer Gallatin National Forest. The campground sits in a forest of aspen and pine trees on the banks of the Main Fork of Rock Creek, within walking distance of Greenough Lake. The Beartooth Range provides a dramatic backdrop. The campground offers 18 single-family campsites, two of which are ADA accessible. Each site includes a picnic table and campfire ring. Accessible vault toilets and hand-pumped drinking water are available. Firewood bundles can be purchased from the campground host. Greenough Lake provides opportunities for canoeing, kayaking, and rainbow trout fishing. The Main Fork of Rock Creek is also a popular fishing stream. Hikers can access the Beartooth Wilderness via the nearby Hellroaring and Lake Fork trailheads. The Parkside National Recreation Trail offers mountain biking and hiking. Yellowstone National Park's northeast entrance is 55 miles away via the Beartooth Highway.
