We followed our RV GPS and it showed the campground (CG) as being at the dam, but we had about 5 miles more to go. There were reviews that the road to the CG areas was challenging. We had called the ranger station and asked if we could get a 39’ 5th wheel up the road and had asked on our FB owners group, both said yes just take it slow. The “fun” starts at the dam with the most challenging portion being after the turn-off for the first CG, McCormack CG, which has sites with 30 AMP and water. We added a video to this review showing the drive  to Indian Creek CG about a mile further up the road. We are seasoned 5th wheelers and went slow with no problem. While we were there a 42’ 5th wheel came in with no problem as well. If you decide to bring a big rig especially the first time, suggest arriving/departing on a non weekend day to try and avoid meeting up with a boater on the single lane road. The lake gets a lot of daily boat activity with most boaters in by 9:00 AM and out around 3:00 PM. When you enter the CG you are on the first level where the camp host resides. There are info boards on which one had the name of people coming in with reservations, but there was no formal check in. There was no problem getting to back-in site 62 with water and 50/30 AMP. Sites 62-67 are on the upper 3rd level. Water pressure was about 40 psi and no issues with the 50 AMP. There is no cell phone service here and we knew that coming in. You are about an hour away from amenities so plan accordingly. Near the dam, there’s a small hut that rents kayaks etc. and states WiFi is available, but we didn’t try it. We did set up our satellite and as there are no shade trees on the 3rd level there was a clear shot to the southern sky. The 2nd level has some trees plus two cute little cabins, and more trees on the 1st level. There are several vaulted restrooms in the CG and at the boat ramp. Sites in both CGs vary in size but seemed consistent with website size descriptions. The dump station is back up the road at the McCormack CG along with the shower houses. Have to say the drive was well worth the stunning mountain and lake views. We had mule deer and a covey of quail visit us mornings and evenings. Even in mid August, we pretty much had the CG to ourselves, Mon- Thurs.
