A very busy park in summer
This state park has a campground and a separate day use area for swimming and picnicking. The campground is family friendly and most of the sites are near the water. If you are looking for privacy and quiet, I recommend the F Loop. The other loops have sites close together and it is generally quite loud during the day. Quiet hours at night are not strictly enforced so you may hear people up and around until midnight or later.
We launched our kayaks from the day use area because the campground boat launch was extremely crowded. From here, we paddled south to the end of the pond and up the Pachaug River, eventually reaching the dam at Pachaug Pond. It's an 8 mile paddle with some tricky spots to navigate, but very pretty! This park also has plenty of trails for hiking and geocaching. The pond has some really big fish, but it's heavily covered with lily pads and there are a lot of submerged trees. If you're going fishing here, a weedless rig is the way to go.
