Even though Smuggler's Cove became our "Go To" beach for the week, we did enjoy a day on one end of Long Bay.
To get there, drive through the Long Bay Beach Resort complex. The road will veer to the left (see posting for Smuggler's Cove) -- an entrance to the beach is right there at the curve. Park anywhere you can on the side of the road. There was an open area on the right, before the curve, where a few cars can squeeze in.
Nature Boy was the only vendor on the beach. He has a makeshift bar that serves about anything you could wish for while on the beach. Full bar, but no food (at least not that day). He also had boogie boards for rent at only $5 each -- what fun!
