Maine’s Premier Four-Week Boys Camp Camp Cobbossee is a 4-week overnight summer camp for boys located on gorgeous Lake Cobbosseecontee in Maine. At Cobbossee, we help deepen the strong relationships between members of our community through sports and adventure. These two focuses are augmented by our awesome waterfront and our peerless residential life program. The result is a very warm, healthy, and joful place where boys become brothers through sports and adventure. Free from the distractions and pressures of life back home, Cobbossee boys thrive here, all while learning values that change their lives for the better. Camp Kippewa for Girls, our sister camp, is 1/2 mile down the road.
