Cobscook Bay State Park is located on U.S. Route 1, four miles south of Dennysville. "Cobscook" is a Maliseet-Passamaquoddy word for waterfall, referring to the falls that reverse with each change of the 24-foot tides, the highest in Maine. Many campsites and shelters are on the water's edge, secluded among spruce and fir trees. In addition to boating and hiking, visitors can enjoy day trips to nearby
Quoddy Head State Park, Shackford Head, Roque Bluffs State Park, Moosehorn National Wildlife Refuge, and Roosevelt-Campobello International Park on Campobello Island in New Brunswick. Hot showers are available. Groomed cross-country ski trails are available in the winter.
