The Boy Scout's Camp Bell, on Manning Lake, was previously
known as Camp Leo from 1946 to 1986 and had a colorful and interesting history before being shut down. Before this, it was
known as Camp Manning. Follow the link below for more information.
".....But don’t get the idea that it was all work and no play on Diamond Island! Especially
when the Boy Scouts came to visit. Heavily involved in Scouting in Lincoln, Mass, Carroll Spooner invited the Boy Scouts from
Camp Manning in Gilmanton to paddle to Diamond Island and spend every Tuesday overnight before paddling back to Alton Bay
where the Scouts were picked up. “Dad knew that Diamond Island was a great place for the Scouts to come and I loved
scouting, so it was just great! Girl Scouts from Boston also paddled to the island from their camp on Treasure Island to spend
the night.”
