Marine Park Salt Marsh Nature Trail

The nature preserve building has one, and there are restrooms in the park across the street (Avenue U)

Would not say it's crowded, but it may be difficult to find solitude for longer than a few minutes

Yes, to the left of the entrance. Look at the satellite view if you need specifics.

Yes. However dogs must be on leash. This is a wild portion of land and it is recommended that your dog be secured. It is a beautiful walk. You'll hardly feel that you are in the city. Please respect the natural surroundings of this area.

Free
