My Son and I stayed here while visiting Mount Rushmore and the surrounding area's other attractions. There's a lot of dispersed spots here but most spots don't have a fire ring that I could see. There's only a few spots that a high clearance vehicle might be required but most of the road can be explored without one.
This is a pack in and pack out site with no facilities; no running water, no bathrooms, nothing. Make sure you bring what you need with you.
Weather was great, very mild. Air was fresh and crisp.
We are planning on staying here again in the future because of it's close proximity to everything and my 6 year old loved it!
