Cobscook Bay State Park is a great base for family camping and explorations in easternmost Maine. Many of the park's 106 campsites (both for tenting and RVs) border Whiting Bay, a sheltered inlet within the larger bay. The Park offers a boat launch for those with the experience to handle boating in challenging conditions (with rapids created by fast-moving tides).

Cobscook Bay is an unusual estuary with a narrow opening to the sea, a long and convoluted shoreline, and relatively few feeder streams and rivers. Nutrient-rich salt water flowing in from the Gulf of Maine stimulates plankton growth, which in turn feeds a vast array of invertebrates (such as shellfish and marine worms). Eagles, ospreys, seals, otters and even the occasional bear enjoy the Bay's abundant fish, including smelt, alewives, shad, sea-run brook trout, striped bass and the Atlantic salmon.
