Bear Brook State Park, with over 10,000 acres, is the largest developed state park in New Hampshire. Located in the southeast region of the state, there is plenty to do and see for everyone. Forty miles of trails through the heavily forested park lead to seldom visited marshes, bogs, summits, and ponds. The park offers a variety of options for hikers, mountain bikers and equestrians. The parks has a day-use area, group areas, and a 101-site campground. Boat rentals are available on the weekends for campers at the campground beach..
