Although Otter Brook Preserve is one of our quieter lands open to visitors, it is our largest preserve in southwestern New Hampshire with 5 miles of maintained trails! Otter Brook spans 1,300 acres of the Andorra Forest and has very important wetland and riparian habitats perfect for bear, moose, beaver, black ducks, and so many more species. Come enjoy this quiet but expansive preserve and help to maintain the trails to ensure that they are safe and clear for all that discover this hidden gem!
