I just happened to drive by, noticing the small bodies of water on either side of the road. Where I stopped didn't have a lot of parking, but I was lucky to get a spot next to two other vehicles. The area seemed to fit four comfortably.
Across from where I parked is a map of the area and in that immediate location seemed to be ongoing construction. The map showed a two mile hike called "the friends loop." I began the trail just past where my vehicle was parked.
It's an easy trail that takes you along the edges of Collins Pond and Brackett Pond, beautiful the whole way. When I went it was the day after a heavy rain so some of the trail was soggy and some streams overtook the planks that would help you cross so there's some navigating and leaping along the way.
The park seems huge, happy to come again and see the rest.
