Emery Bay Campground is located on the Hungry Horse Reservoir, high in the Rocky Mountains, less than 30 miles from the Continental Divide, surrounded by towering mountain peaks. Visitors can expect a variety of recreational activities, including fishing, boating, swimming, hiking, exploring and big game hunting. This Campground has 26 sites, 16 of which are reservable and 10 are walk-up sites. The stay limit is 16 consecutive days.
Boating is popular on the 27,750-acre reservoir, and a native boat ramp for smaller watercraft is available. Swimming and fishing are also popular pastimes, and anglers can expect a catch of cutthroat trout and other varieties.
The campground offers 26 campsites, including some first come, first serve, available for tent and RV camping. Two group campsites are also available and can accommodate up to 75 guests on each separate loop.
Each site is equipped with tables and campfire rings with grills. Vault toilets are provided. Also drinking water is provided after June 15th. Water is not a fill station so please come with your RV water full. An on-site host is available to answer any questions about the campground and surrounding areas.
The campground is situated along the massive Hungry Horse Reservoir, which was dammed to provide hydroelectric power and flood control to the area. It is the 10th highest dam in the United States and provides a stunning backdrop.
From Martin City, Montana, turn off Highway 2 and continue on the main road through the town heading south. This road becomes East Side Reservoir Road. Continue for about 6 miles into the campground.
