About
South Trout Lake Campground, sites 1001-1023, is located in the central portion of the forest on the southeast corner of Trout Lake. This 3,816-acre lake is very deep and offers excellent boating and fishing. Swimming is limited because of the stony lake bed. The campground has one vault toilet building, one hand pump for drinking water, separate trash and recycling dumpsters, a boat launch and access to the paved bike trail which goes to Crystal Lake and St. Germain in one direction and Boulder Junction in the other. A sanitary dump station is available at the North Trout Lake Campground.
Sites 1003-1004 and 1006-1007 are double campsites. They accommodate up to 12 people and two-wheeled camping units.
Sites 1013-1016 are walk-to, tent-only sites where campers must walk a short distance from their cars to the campsite.
This campground is open the Thursday before Memorial Day-Labor Day.
23 campsites on the reservation system. In Northern Highland-American Legion State Forest.
