About Greenough Lake Campground
Overview
Greenough Lake Campground is within walking distance of its namesake, 12 miles south of Red Lodge, in southern Montana. It is located just off the scenic Beartooth Highway. The area is a popular location for fishing, hiking and scenic driving. Glacier Lake, Hellroaring and Lake Fork trailheads are nearby.
Recreation
Greenough Lake offers canoeing, kayaking and rainbow trout fishing. The Main Fork of Rock Creek is also a popular fishing stream.
The Beartooth Wilderness can be accessed via the Hellroaring and Lake Fork trailheads, both of which are not far from the campground. Visitors also enjoy mountain biking and hiking on the Parkside National Recreation Trail. Hellroaring Road is open to off-road vehicles.
Facilities
The campground offers single-family campsites, two of which are accessible. Each site is equipped with a picnic table and campfire ring. Accessible vault toilets and hand-pumped drinking water are provided.
Natural Features
The campground sits in the shadow of the Beartooth Range, on the banks of Rock Creek, less than a quarter-mile from beautiful Greenough Lake. A forest of aspen and pine trees covers the area. A variety of wildlife, including grizzly bears, deer and elk, makes its home in the surrounding area.
Nearby Attractions
The charming town of Red Lodge, Mont., offers a variety of dining and lodging options, galleries, shops and annual summer events. The Home of Champions Rodeo is held on the Fourth of July weekend, the Beartooth Bike Rally and Iron Horse Rodeo take place in mid-July, the Mountain Man Rendezvous is in late July, and the Festival of Nations happens in early August.
The Beartooth Highway was deemed "the most beautiful drive in America," by the late Charles Kuralt. It snakes across the rugged Beartooth Mountains from Red Lodge to Cooke City. It is the highest elevation highway in the Northern Rockies. Along the way, visitors are treated to sweeping views and plentiful opportunities for outdoor recreation.
Yellowstone National Park's northeast entrance is 55 miles from the campground, via the Beartooth Highway. The park offers unparalleled wildlife viewing opportunities, as well as breathtaking scenery and unique geological features.
