Thompson lake campground is a small secluded camp with plenty of of space between campsites. We had site 10 at the top of the loop, it was easy to back into and had water and electricity. Since Thompson lake is in the tri state region , you can easily drive to Rhode Island and Massachusetts.

Showers are in need of work. There is not enough hot water to provide more than one shower at a time and even then it's iffy to have enough for a complete shower. This has been an ongoing issue for years.

Clean facilities. friendly, helpful staff. The disc golf course is great. The firewood wasn’t the greatest but, besides that a great experience.
