We really liked the campsite. It was nice and secluded.
We made our reservation the day before our check in date. We tried calling Stephen (the owner) several times the morning of and again about 10 times upon arrival as we were unsure where the site was (the roads were a little confusing) but we couldn't reach him and his voicemail was full. It was a little frustrating after driving 3+ hours.
We eventually found it and were lucky to find one other group staying there who confirmed we were in the right location. We set up camp and had a great first night's stay. It wasn't until the next afternoon that we eventually saw Stephen when we were swimming in the river as he was collecting parking money from other river visitors. He didn't have any idea we were staying at the site, but we explained that we made a reservation on Hipcamp and had tried calling many times. All was well and the rest of the stay was fantastic.
All in all the location was great and we really enjoyed having easy access to the river for swimming. I think once the kinks are worked out with the check in logistics and bathroom, it will make a really great camping location. I will say that the "exclusive access" is a little misleading as there were about 100 other people at the swimming hole throughout the day we were there swimming.
