We camped at Cooks Lake for two nights, this past Friday and Saturday. There were 4-5 camp sites at the main campground, well-separated and each with a fire pit. There is a vault toilet that was disgusting, beware. Swimming/small boat access is through the main campground.
Hop out onto the road and keep heading the same direction and you'll come to a couple of other little pods of sites, most had fire pits, and they were fairly level and well-separated as well.
We turned around and went back and past the main campground, and took the next downhill driveway toward the lake. The driveway ends at a decent raised fire pit with a ledge for a pan or pot. There is a small level area there for chairs. Past the fire pit, it slopes down to the lake. The beach is dirt and sharp rock, and mostly sloped, probably 150 feet long? and narrow. There is another steep entrance to this beach at the other end, from a pullout on the road above. We decided to stay there because it felt pretty secluded, and there was one spot that was level enough for a tent…there was 12" of beach between the tent and the water!
We were 'invaded' by groups of fishermen/women/families both mornings pretty early, one was rude, one was quiet. But, the early mornings on the lake were worth it. The mist rising and the vast, green mountains, right in front of you! Birds everywhere, woodpeckers in the birch trees and killdeer darting down to the water. Chipmunks and rabbits. Tadpoles and turtles and little water snakes. The water was warm and we swam all day. Bats at night, and the stars!!
Excellent camping experience.
