The Marieta Islands exist just off the coast of
Puerto Vallarta in Mexico. They are said to have been formed centuries ago due
to volcanic activity and are uninhabited by people. Just an hour long boat ride
from the coast of Puerto Vallarta will see you to these islands, which are sure
to floor you in their sheer physical beauty and splendor. Military testing in
the early 1900s is said to be the cause of the incredible caves that exist
there today, but after the push from infamous scientist, Jacques Cousteau, in
the 1960s, the site is now a registered national park. When you visit the
Marieta, you can swim through a water tunnel leading you to the elusive hidden
beach. It’s not an underwater tunnel, however, so you won’t need to hold your
breath… but it’s guaranteed that this site will take your breath away.
