Hi there,
There are over 60 state parks in New Hampshire located in every region of the state. You can camp and enjoy activities like fishing in parks such as Franconia Notch State Park in the White Mountains.
Twelve of the
New Hampshire state parks are historic sites which also offer tours. To name a few, you have the Fort Constitution Historic Site, the lovely Robert Frost Farm in Derry near the Massachusetts border, and the beautiful Wentworth-Coolidge Mansion in Portsmouth.
Hampton Beach State Park is a great place if you want to enjoy miles of sandy beach near the ocean. Also, Ellacoya State Park on Lake Winnipesaukee offers a swimming beach and small boat launch ramp.
Hope this helps
