Designated campsites on the West side. Situated to the north of Great Diamond Island in Casco Bay, Cow Island is open to the public for low-impact recreational use.
Rippleffect owns this 26-acre island with responsibility to protect Cow's natural ecosystem and public access. From its island headquarters in Battery Bayard on the east side, Rippleffect leads experiential, environmental programs for area teens & adults. The best access to the island is on the northwest side.
During programming; Monday thru Sunday, June thru October, please confine your exploration to the west side. At other times, you're welcome to explore the entire island. You'll find vestiges of gun emplacements, batteries and bunkers from both World Wars. There are manholes throughout the island. They are mostly covered, but please watch your step. Use established trails and stairways to help preserve delicate plants. Clean-ups and restoration projects are ongoing; if you wish to assist, check in with staff members or call Rippleffect.
Both Rippleffect and the Maine Coast Heritage Trust request that you follow all posted guidelines and leave Cow Island better than you found it. Your cooperation is appreciated.
