I had came through Devil's Tower late at night with my family hoping for a spot at the National Park. Unfortunately, they were full, but Camp Barlow was available on The Dyrt app and I was able to book. Charlie, the owner, was very kind and accommodated us.
The Camp is new with brand new picnic tables, fire rings, a porta-potty and water.
I highly recommend this place! Rv-ers and campers, check it out!
