Trail Map

The hollow of Bigelow Hollow is formed by ridgelines to the east and west and when combined with the surrounding forests, it forms one of the largest unbroken tracts in Connecticut.  The state park property only encompasses Bigelow Pond to the border of Mashapaug Pond and it is bordered to the east and west by Nipmuck State Forest land.  The two properties are so closely networked that they fall under the same heading at the DEEP. 


The park property has about five miles of trails including the yellow Bigelow Pond loop and the blue/white Mashapuag Pond View Trail.  These trails connect to those in the Nipmuck Forest for a total of 35 miles.

The area has a 3 mile stretch of the blue blaze Nipmuck Trail that serves as it’s northern terminus where it meets the Massachusett’s border


The best swimming here is off the rocks on the peninsula a short quarter mile hike northwest of the boat launch on Mashapaug Pond.


These trails also provide access to camping shelters along Breakneck Pond.  Applications for camping permits can be found here.


There are boat launches to Bigelow Pond (24.5 acres) and Mashapuag Lake (287 acres) along the park road.  The links provide overviews, pictures, and guidelines.


Established as a state park in 1949 from Nipmuck State Forest land.  The origin of “Bigelow” is a mystery.
