The East River launch is a sandy boat ramp located off US 41 (Tamiami Trail), 5. 2 miles west of SR 29, offering access to a 5. 6-mile brackish paddling trail through mangrove tunnels and lakes to Fakahatchee Bay.

This intermediate to advanced paddling destination features a port-a-potty and picnic table, but has limited parking and no trail markers—bring a map and GPS/compass, and check tides before launching as the waterway is heavily tide-dependent.

The area is popular with outfitters and offers excellent wildlife viewing opportunities including alligators and wading birds, though paddlers should respect nesting bird rookeries along the trail.
