Situated in the sparkling waters of Banderas Bay, the Marietas Islands consist of two larger islands—Isla Redonda and Isla Larga—and several smaller islets, together forming a protected National Park and UNESCO Biosphere Reserve. Often called Mexico’s “Hidden Beach” or “Beach of Love,” the islands are famous for their crystal-clear waters, abundant marine life, distinctive caverns formed by past military activity, and pristine sandy beaches accessible only at low tide.
The islands’ volcanic origins, combined with past military bomb testing, have created one-of-a-kind natural formations, underwater caves, and an enclosed beach hidden inside a crater, making Marietas a haven for snorkelers, divers, bird watchers, and adventure travelers.
History of Marietas Islands
The Marietas Islands were formed thousands of years ago through volcanic activity on the Pacific Coast. In the early 1900s, their uninhabited status led the Mexican government to conduct military bombing tests here, drastically altering parts of the landscape and creating unusual rock formations and submerged caverns.
Due to increased environmental concerns and international pressure (notably by Jacques Cousteau), the islands were designated a National Park in 2005 and later recognized as a UNESCO Biosphere Reserve. This protection prohibits fishing, hunting, and most human activity to preserve fragile marine ecosystems, bird nesting grounds, and coral reefs.
The islands are located approximately 22 miles (35 km) northwest of Puerto Vallarta and about 5 miles (9 km) off the Punta de Mita peninsula, making them accessible yet feeling like a remote paradise.
