Cow Island

Situated 300 yards to the north of Great Diamond Island in Casco Bay, 26 acre Cow Island is being transformed by Rippleffect into an educational outpost for the regional community. The Maine Coast Heritage Trust holds a conservation easement for Cow Island which protects public access in perpetuity. From May through September, Rippleffect offers adventure programs to area youth, operating primarily from the east side of the island. Click for Map
