Hartman Creek State Park offers accessible fishing piers along the east shore of Allen Lake and at Whispering Pines on Marl Lake, both designed for persons with disabilities.

The park office provides free basic fishing equipment through the Tackle Loaner Program, and bait is available for purchase at the Adventure Outfitters Outpost near the swimming beach.

Paddlers can launch canoes and kayaks from the boat landing off Knight Lane on Manomin Lake and paddle through the park's waters to reach Whispering Pines Picnic Area, which has parking, restrooms, and amenities.
