North Marathon Shores Public Boat Ramp features a single paved ramp with docking facilities and is open 24 hours, making it convenient for boaters in the Marathon area.

The ramp is free to use and includes a picnic area and parking for cars and trailers, though parking is very limited (capacity for 1-2 trailers and 2 cars).

Note that the ramp is located adjacent to a residential neighborhood and lacks fuel, bait, and restroom facilities.
