Although Connecticut might be called “The Constitution State” or “The Nutmeg State,” it could also be called “The Forest State.” About 60% of the land is woodlands, first in the country in the percentage of urban lands covered by trees. Bigelow Hollow State Park and the Nipmuck State Forest are significant areas in northeastern Connecticut to enjoy the beauty of America’s forests. Let’s look at all this area has to offer!

It’s nearby the Nipmuck State Forest, the second oldest state forest in Connecticut, with the first parcel of land acquired in 1905. In 1949, Bigelow Hollow established a recreation area, and visitors today can enjoy over 9,000 acres between Nipmuck State Forest and Bigelow Hollow State Park.

How Much Does It Cost to Visit Bigelow Hollow State Park?

About Bigelow Hollow State Park

No one is quite sure how Bigelow came about since no one by that name is associated with the park’s history. However, “Mashapaug” means “Great Pond” in the Nipmuck Indian culture. There are boat launches at Mashapaug Lake, also called Mashapaug Pond, and Bigelow Pond, two prime places for fishing in the area.

Traveler’s Tip: Summer in the northeast can be sweltering, so cool off in our favorite ten lakes in Massachusetts.
