The park is 42 spectacular miles long and no more than 5 miles at its widest. The entire length is traversed by the North Country National Scenic Trail.
Miners Castle Overlook, reached via Miners Castle Rd., gives stunning views of a smoothly curved inlet of white cliffs above a submarine outcrop of yellow sandstone; the offshore water of Lake Superior is intensely blue, but above the yellow lake bed it becomes a rim of vivid green.
At the northern tip of the inlet is Miners Castle, a crag of cliff carved by erosion into the semblance of a medieval castle. A side road from Miners Castle Rd. goes to Miners Falls, a high and narrow plummet between two massive cliffs; at their base are swirl holes, and the face of the nearer wall has been scooped out by erosion.
The park is a camper’s delight. Three campgrounds in the park are accessible by car: Little Beaver Lake, Twelvemile Beach, and Hurricane River.
From Little Beaver Lake it’s a short walk to Beaver Lake and the North Country Trail. The campground at Twelvemile Beach provides access to an unbroken stretch of white sand.
From Hurricane River one can walk 1 1/2 miles to the 1874 lighthouse at Au Sable Point and beyond that to a 500-foot wooden log slide and the Grand Sable Banks and Dunes area.
There are also 13 backcountry campgrounds along the Lakeshore Trail. Scuba divers are catered to along the shore by the Alger Underwater Diving Preserve. Late summer provides magnificent weather, but the park is also beautiful in winter, when visitors flock there for snowshoeing.
Open year-round. Fees for camping.
