I surprised my husband for a mini birthday trip in August of 2015. Yes...we went tent camping in August! The tent campgrounds were pretty empty and we were able to find a nice spot off the road. When we went they were resurfacing the road all the way down to the cave so if you wanted to see the Indian Cave it was about a 2mile hike, which we didn’t mind, aside from the Nebraska, August heat! We loved the hiking trails through the trees and difficult terrain. This camping trip will be another one to complete...maybe in September or October next time 😃
