Bear Brook State Park, State park in Merrimack County, US.

Bear Brook State Park is a protected natural area in southeastern New Hampshire with multiple ponds, forests, and an extensive network of trails for walking and outdoor activities. The park provides camping facilities and allows visitors to explore different sections on foot or by water.

The park was established in the 1940s as a protected area and includes buildings from a major work program started during the economic crisis of the 1930s. Some structures on the site date back several decades and reflect how land management and employment programs operated at that time.

Three museums within the park grounds tell different stories: one dedicated to snowmobiles, another to a historic meeting house, and a third showcasing the work of a major conservation program. Together they reveal how this land has been used and valued by people over time.

The park has camping areas and cabins near water access points for boating and fishing. Wear sturdy footwear when walking the trails to explore different sections comfortably and safely.

The park operates two archery ranges, including one specifically designed with accessibility features for people with different physical abilities. This type of specialized facility is uncommon in nature reserves across the region.
