Grahams Island State Park's boat ramp features a four-lane concrete ramp with five courtesy docks (one per lane plus an additional dock), providing excellent access to Devils Lake for both motorized and non-motorized watercraft.

Nearby amenities include a vault toilet, parking lot, fish cleaning station, and concession store, making it well-suited for day-use boaters and anglers. The ramp is plowed for winter ice fishing access and is available seasonally.
