Sailors Haven and Sunken Forest is a 4 mile out and back trail located near Brookhaven, NY that offers the chance to see wildlife and is good for all skill levels. The trail is primarily used for walking and is accessible year-round.
Nice walk along the beautiful beaches of Fire Island and through the Sunken Forest, a part of Fire Island that I didn't know existed...
Not hard at all...
I actually helped build one of the board walks here way back in high school. Went two years ago, still great.
