Buckhorn State Park's accessible 90-foot fishing pier near the north picnic area offers excellent year-round fishing access on Castle Rock Flowage, with free basic fishing equipment available to check out at the park office.

The pier is fully accessible to mobility-impaired visitors, with nearby amenities including picnic shelters, restrooms, and parking.

Paddlers can access the flowage via a canoe launch on the peninsula's east side and five boat ramps throughout the park, with a self-guided 10-stop canoe interpretive trail available.
