4. El Nido, Palawan, Philippines
With the Linapacan Strait on its northern front, the Sulu Sea and the South China Sea surrounding it on the eastern and the western shores, El Nido is pocket of wonder. The white sand beaches here reflect upon the ample limestone mines here. Swimming through the Secret Lagoon is one experience you would not want to miss out on. The turquoise blue water and the scenic cliffs make for excellent photography.
