I camped at Hidden Acres on the last night of a 12-day solo bike tour in August 2023 as I made my way back toward NYC. I couldn't have better things to say about the experience. They were so accommodating (especially relative to other campsites in the area that I called), and even kept the office open a few minutes past closing to welcome me and help me get situated.
The campsite was beautiful and I camped right along the river, so fell asleep to the tranquil sounds of the slow-moving water. Would absolutely revisit and recommend!
