Little Trinity Lake Picnic Area

No motorboats are allowed on the lake.

Near this Picnic Site, is the trailhead for the Little Roaring River trail, which heads north and is open to motorcycles.

The campgrounds in the Trinity Recreation Area are located in a dense lodgepole pine forest close to the East Fork Roaring River at an elevation of 7,900 feet. The peaks of the Boise Mountains surround the area, and Trinity Mountain is the tallest in the range at 9,700 feet. Snow can make this area inaccessible until early July, but soon afterward, the land is blanketed by colorful summer wildflowers. This area is a haven for elk, deer, and moose, but wildlife watchers may also spot an occasional black bear. 

Anglers can fish in any of the nearby lakes for rainbow and cutthroat trout. The lakes are also ideal for exploring by canoe or kayak. 

For site specific questions, contact the Mountain Home Ranger District.
