The boat ramp at Sea Rim State Park's Marshlands Unit provides access to over 16 miles of paddling trails through coastal marshes, with canoe and kayak rentals available at the park headquarters.

The ramp accommodates shallow draft boats and is located 2 miles from the floating primitive campsite, making it ideal for both day trips and multi-day paddling adventures.

All visitors must register at park headquarters before entering the Marshlands Unit, and air-propelled boats are limited to 10 horsepower.
