Hidden beach ( A cool looking hidden paradise)

Location: Islas Marietas, Mexico

This island is completely ignored one in list of most beautiful islands but this place is just too cool and beautiful. 

Inside looks

A lovers' beach, tucked below the surface of the island, provides a safe heaven for romance.  In 2005, the islands were finally named a national park, Parque Nacional Islas Marietas, making swimming, kayaking, sunbathing, and other forms of recreation the only activity, and prohibiting hunting and fishing around the islands. Also, later on, the park was designated as a UNESCO MAB Biosphere Reserve. 

It is completeky secret looking from outside. Here, beautiful sunrays enter through middle of it in crystal clear blue water making a truly beautiful scene just like a fantasy.
