Camp Tecumseh is located on one of the nicest locations of Lake Winnipesaukee, the largest lake in New Hampshire. Tecumseh owns over two miles of well kept shore line. A well supervised dock is constantly in use by the campers and counselors, especially after the morning or afternoon activities have been completed. Tecumseh also has an "outer-float" with two high dives and a sliding board, for more fun and entertainment at the waterfront.

The waterfront at Tecumseh is host to a wide range of activities. Tecumseh owns and operates two boats for waterskiing. The waterfront staff provides supervision and instruction for both novice waterskiers and advanced waterskiers.

Six regulation sized swim lanes are roped off for both swim meet competitions and for those wishing to practice for their scholastic and swim club seasons back home.

Other activities at the Tecumseh waterfront include waterpolo, canoeing, kayaking, sailing and beach volleyball.

The Tecumseh Weight Room is located down at the waterfront. The Weight Room has a wide variety of barbells, dumbells and other weightlifting equipment. The Weight Room is strictly supervised by the staff which provides instruction and consultation in setting up a safe weight program for the older campers.
