Rush Lake North Boat Ramp is a walk-in access point located off Osborne Road in Nepeuskun Township that provides pedestrian entry to the northern section of Rush Lake's 3,070-acre marsh.

Users should be prepared to traverse over 300 yards of cattail marsh before reaching open water, and the access may be partially obstructed by cattail growth, requiring navigation through narrow channels.

This undeveloped ramp is primarily used by paddlers and duck hunters seeking access to the scenic northern portion of the lake.
