Welcome to the crown jewel of Custer State Park. You'll find Sylvan Lake nestled among incredible granite formations that create a truly breathtaking scene. For an easy and rewarding experience, take the one-mile Shore Trail that loops around the water, offering stunning views from every angle. If you're feeling more adventurous, rent a paddle boat to explore from the water or use this spot as the starting point for more challenging hikes, like the one to Black Elk Peak.
