Great job with the pics....THANKS!
Lighthouse Beach is accessible from the ocean side as well as the boardwalk-Burma Road-1st boardwalk on the right route from Robert Moses State Park Field 5.
The area directly in front of the lighthouse as well as the approximately 100 yards of beach on either side of the lighthouse is clothed. The first bunch of nudes west of the lighthouse is known as the more pervy crowd, while the second group located east of the lighthouse are the "real" nudists who are truly into the healthy lifestyle of being "clothed with the sun."

Ha!
Stay out of the dunes, be discreet and watch for rangers in the 4WD...they'll do anything to stay friends with the nude chicks who flag them down for a nude conversations. There's alot of east-west foot traffic near the water....mostly clothed people from Robert Moses Field 5 "taking walks" - in other words, gawkers. Notice how many groups of teenage girls take the trip down to giggle and cock-watch.
