Garnet Lake Boat Ramp is a hand launch facility located at the end of Garnet Lake Road on the northeastern end of the 302-acre lake, with parking for 6-7 cars and a boat assist structure to help load boats from trailers into the water (note: trailers cannot reach the water directly).

The site includes a trailhead register and provides access to six designated water-access campsites around the lake and the Lizard Pond Trail on the southwest shore.
