Fuller Lake offers two access points: a boat ramp on the northwest corner with ample parking and a picnic area ($10 launch fee), and a dam access on the south end with minimal parking for bank fishing.

Day-use only (sunrise to sunset, May 16–first snowfall), the lake accommodates small watercraft like kayaks, canoes, and float tubes with a 10 mph speed limit and electric motors only; a $7 per vehicle day-use fee applies.
