I’ve been going here since i was a kid and it has changed in that it has been discovered! The island is really a great northeast weekend getaway but i avoid it now during the peak season. Best time to go is right before the summer or better still right after labor day. The prices go down drastically and it is once again a serene place to go biking, hiking, walking or just laying by the beach.
As for the beach, there is a great area that is completely secluded …all u need to do is find the painted rcok and follow the long trail down through the dunes. Hint: it is off of the mohegan bluffs.
Also, if u like to sail this is a great place to dock.
