Eco Tours Marietas Islands Snorkeling Overview

The beautiful Marietas Islands are a nature enthusiast’s dream; they are home to an astounding array of plants and animals both above and below the water of Banderas Bay. A n array of sea birds nest on the isles’ craggy exterior, including frigate birds, egrets, boobies, herons, pelicans, and seagulls. The caverns and crevices of these islands, spawned by volcanic activity, provide the perfect environment for aquatic birds to nest. The bird-watching at wildlife sanctuary is well worth the excursion to the Three Marietas (Las Tres Marietas) for nature-enthusiasts; visitors can also explore the crystal-clear waters surrounding these while snorkeling. The Marietas Islands are home to some of the finest snorkeling spots in Bahia de Banderas (Banderas Bay), and perhaps, the whole planet. The expansive coral gardens in this area near the mouth of Bahia de Banderas provide a thriving habitat for a remarkable kaleidoscope of exotic fish and other marine species, including Olive Ridley Turtles, giant mantas, octopi, and sea horses. Banderas Bay is home to over 200 types of fish, including the Sergeant Major, the Angel-fish, the Rainbow Wrasse, the Cortez Chub, the Moorish Idol, and the Giant Damsel-fish.

What distinguishes this Marietas excursion from others is the method used to arrive at this island grouping at the mouth of Banderas. You will begin your adventure by riding in an air-conditioned van to the quaint and secluded fishing town of Punta Mita. You can experience the authentic charm of this hamlet on the north coast of the Bay. After dining on a scrumptious lunch on the beach, you’ll only have a 20 minute cruise out to Tres Marietas for some once-in-a-lifetime snorkeling.
