Leashed dogs are welcome. Dogs are not allowed in the park or historic buildings or public swimming areas and beaches. The wilderness qualities and geology of Johnson’s Shut-Ins State Park and the surrounding St. Francois Mountains make this park a special place to visit. Its rugged character provides the perfect backdrop for camping, hiking, picnicking, splashing in the shut-ins, exploring nature or just relaxing. The best way to access the shut-ins valley is on the Black River Trail, 3.15-mile loop.This trail system was developed to connect people with the different features of the park, including the campground, the day-use area, the interpretive center and the trail leading to the shut-ins.
