East Harbor State Park's marina ramp provides access to West Harbor with a direct channel to Lake Erie, offering seasonal and day-use dock rentals, fuel, a full-time mechanic, and boat supplies for a fee.

The park also features a free boat ramp in the campground (campers only April-October, public access November-March) and a carry-in kayak ramp at South Beach for calmer waters.

Additional amenities include a 1,500-foot swimming beach, 11+ hiking trails, fishing access in Lake Erie and both harbors, and a 571-site campground with full facilities.
