Nice and relaxed atmosphere. Good bathroom and shower. No store, most tent site are level. Couple tight turns into RV spots but overall SOLID place. Nice walk around Thompson lake, however Webster lake is a short drive with lovely water to swim and fish.

This campsite was delightful! Very quiet and each site offers a good amount of privacy. It was also super clean and well maintained. We will definitely be back!

Overall has not been a good experience and won’t be coming again, our tenting campsite was covered in gravel so we decided to put 2 tents in the grass 5 feet off the gravel. We almost instantly got told we need to remove our tents and put them back onto the dedicated camping area, again on rocks and gravel. The lake is not worth fishing in and you’re forbidden to swim in it. Also only catch and release. Ontop of that the lake was taken over by a group of people with rc boats and we were told by them to only stay near shore and not to go into the middle or the lake. If you want to come here for fishing don’t, if you want to swim don’t come here. Quiet time at 9

I very much enjoyed my stay here! I have lot 15 and it was located perfectly. Enough privacy to enjoy my time and close enough to the restrooms. There is a playground close by so expect the sound of kids if they’re at camp. I loved my time there. Hiking to the lake shore was a breeze and really quite beautiful. I would definitely recommend this campground! Everyone was so kind from Russ at the front shack to every camper I ran into.
