Very beautiful area! Take some time to hike around and do some climbing. The lodge is a good stop as well.

This lake and surrounding area are so beautiful that we commented to each other how it almost looked Disney-like or unreal. Fishing, hiking, swimming, or just sitting are all good ideas here.

This was a nice surprise during our ride through Needles Highway. Gorgeous lake where you can get out and stretch, have a bite to eat or have a bathroom break.

We hiked around it is all that we did. There was so much to do. People were fishing, paddle boarding, kayaking, and swimming at the swim beach.

It’s very general. There are good grocery stores in Rapid City, Hill City, and Custer. Load up on what you need before you get to Sylvan.
