The Umbagog Lake State Park is a state park and recreation area in Cambridge, New Hampshire. It is one of the newest additions in the state system, being only acquired in 1998.

The Umbagog Lake State Park is a pretty unique location, featuring a remote lake. It has a base park campground that has 27 sites in it with hook ups. The other campsites are situated in more remote locations around the lake, some of which are even only accessible by boat.

Activities available at the Umbagog Lake State Park include swimming, camping, boating, fishing, and wildlife viewing. Visitors can also enjoy canoeing, kayaking, and rowboating. Boat rentals are also available, as well as transportation to more isolated areas inside the park.
