Located behind old Lazaretto Quarantine Building. Degraded concrete boat ramp that is still useable. Parking permitted in designated areas of the Lazaretto and Lazaretto Ballroom (Behind Tinicum Fire Co.) Vehicles not permitted to enter construction site behind building. Portage required from parking lot through construction area (dirt lot) to boat ramp. Do not drive up to ramp. Again vehicles not permitted beyond gate. Portage distance...550 feet from parking near gate to ramp. Completely doable if you have a kayak cart. Surveillance camera believed to be on site. Use at your own risk. I have launched and recovered in police presence with no issue. I did not hang around though, I made my launch and recovery quick each time. Prep at your car and stow away at your car. In and out and you should be fine. Be respectful and do not wander and this will be a good alternate launch for you.
