About
Hidden beaches, volcanic rock formations, and a rainbow of marine life – the Islas Marietas offer an adventure that is truly otherworldly. The islands themselves are the product of ancient volcanic activity and lie just off the coast of Riviera Nayarit. They've long been a favorite with explorers and conservationists. In the early 1900s, they were used as a military testing ground, which resulted in the formation of a number of caves and open craters. One of the most famous of these is Playa del Amor (Hidden Beach), which is only accessible by swimming through a tunnel in the rock. It's one of the most exclusive beaches in the world.
The islands are a national park and a UNESCO-protected biosphere reserve due to their biological wealth. There are very strict visitor numbers and conservation rules in place to protect the delicate habitats of the seabirds, the rare reef fish, and the endangered species such as the blue-footed booby. It's now a haven for eco-tourism, with visitors from all over the world coming to experience the wildness of the place both above and below the water. Tours leave daily from Punta Mita and Puerto Vallarta, giving you the opportunity to see the island in all its glory whether you're snorkeling, kayaking, or just lying in the sun.
Islas Marietas: Fun Facts & Cool Features
One of the most well-known features of the Marietas is Playa del Amor (Hidden Beach). This sun-drenched patch of sand is tucked away in a crater and is only accessible by swimming through a low tunnel (so it's definitely a bucket list item for the intrepid). The islands are also home to a number of rare species of wildlife, including colonies of blue-footed boobies whose blue feet and rather bizarre courtship dances are a joy to see.
Snorkellers and divers will find a paradise of coral reefs and pristine waters teeming with life (colorful fish, manta rays, occasionally sea turtles and dolphins). Above the water, the sheer cliffs and caves provide a stunning setting for kayaking and paddleboarding. The highlight of the season is, of course, whale watching, with humpbacks passing through the waters from December to March, leaping and singing in abundance.
From secret beaches to spectacular wildlife, Islas Marietas is a must for anyone seeking adventure and real natural beauty on a Riviera Nayarit holiday.
