The Marina Area boat ramp at Codorus State Park provides public access to the 1,275-acre Lake Marburg with an observation area overlooking the eastern portion of the lake, popular for viewing waterfowl and bald eagles.

The marina includes docks, boat rental services (including pontoon boats, kayaks, and canoes), a fuel dock, and amenities such as restrooms, parking, and a convenience shop with fishing and boating supplies.

Motorboats are limited to 20 hp/15 kWh, and mooring spaces are available seasonally (April 1 - October 31).
