So much to do! They offer a ton of programs for the whole family. I've hiked here numerous times and am really debating buying the annual pass. Clear trails, activities and always a friendly face. There are moonlit hikes, educational presentations, picnic and camping areas. The fee is $6 per car despite the amount of people you have jammed in there. Take note that Wind Cave has a bee colony at the top, avoid them and they avoid you. Bring plenty of water. This park will not disappoint.
