Sylvan Lake is probably the most recognizable of the five Custer State Park lakes, and of any of the Black Hills lakes for that matter. Its definitely my favorite. It is featured in the Nicolas Cage movie “National Treasure 2: Book of Secrets” (although the location may seem off). There is a 1 mile path around the lake that is mostly easy and accessible near the front. It gets a little rocky and steep along the backside of the lake, but the vistas are beautiful and well worth it.
