Island Marina

Island Marina in Tinicum Township offers boat ramp access to the Delaware River, a major waterway with significant current and flow. The Delaware River at this location is a major stream (Stream Order 8) with an average flow of over 30,000 cubic feet per second and typical velocities around 3 feet per second, making it suitable for experienced paddlers and motorboaters. The river's 2.7 ft/mile average gradient means this tidal section generally has moderate current conditions that vary with tide and seasonal flow.

This access point is conveniently located in the Philadelphia area near Tinicum Township, close to John Heinz National Wildlife Refuge at Tinicum—a valuable destination for wildlife viewing and nature-based recreation. The proximity to Philadelphia International Airport and nearby services makes this a practical launch point for day trips or longer paddling excursions on the Delaware. A valid Pennsylvania boat registration or launch permit is required to use this access site.

Paddlers and boaters should be prepared for the Delaware's substantial current and volume, particularly during high water periods. Check current conditions before launching, and be aware of tidal influences if paddling in this lower estuary section of the 332-mile Delaware River system.
