Koser Park in Bainbridge offers a small boat ramp and limited parking for access to the Susquehanna River, serving as the southern trailhead for the Conoy Canal Park Trail and Northwest Lancaster County River Trail.

The park features a pavilion and benches with scenic river views, making it popular with paddlers and cyclists, though boaters should check water levels before launching—conditions become hazardous below 3 feet due to numerous rocks.

This access point is best suited for paddle boats and small craft rather than large motorboats or fiberglass v-hulls.
