For those interested in learning more about our natural and human history, a trip to the museum complex, located in the park one-half mile from the toll booth, is a must. A 4-H Nature Center is featured at the park. Interpretive programs are held regulary throughout the summer season. Also located in the museum complex are the New Hampshire Antique Snowmobile Museum, Museum of Family Camping, Old Allenstown Meeting House, and the Richard Diehl Civilian Conservation Corps (CCC) Museum. Most of the museums are housed in historic CCC buildings. Listed on the National Register of Historic Places, the Bear Brook Camp is one of the most complete camps remaining intact and in use in the country. The museums are open at various times throughout the summer. The Museum of Family Camping is open daily from late May through mid-October.
