Long Pond Boat Ramp in Mount Desert offers a hard-surfaced concrete ramp suitable for launching motorboats (no horsepower limit), canoes, and kayaks, with a separate gravel area for kayak/canoe launching.

The facility includes a parking lot, designated swimming area, and access to hiking trails (Long Pond Trail, Valley Trail, and West Ridge Trail).

Note that swimming and water activities are prohibited within 1,000 feet of the water supply intake located at the ramp, though these activities are permitted at other areas of the lake.
