Sylvan Rocks is the Black Hills’ premier rock climbing guide service since 1989. The time you spend with us is not just spent doing or watching, it is becoming part of something. The goal of our experienced staff is to get you on the rocks climbing at your level and making memories that will last a lifetime. We offer climbing tours at Custer State Park/the Needles, the Mount Rushmore Climbing Area, Devils Tower National Monument, and Palisades State Park (on the eastern side of South Dakota).
