The Hidden Beach still remains unsullied due to the difficulty of getting to it. But in any case being hoisted down from a helicopter, the only known way to access it is though a very small opening on the tidal side of its cavernous walls and this short tunnel, measuring fifty feet with only 6 feet of air space between water and rock, can only be traversed by swimming or scuba diving, and only during low tide.
The island was formed thousand years ago and protected by the government of Mexico, and visitors who intend to enter the reserve must have a permit. Now it is a UNESCO World Heritage Site.
