Las Islas Marietas National Park Adventures

Las Islas Marietas National Park comprises a group of small uninhabited islands located about 6.5 miles (10.5 km) off the coast near Puerto Vallarta, Nayarit, Mexico. Created in 2005 to protect its fragile ecosystem, the park covers approximately 1,148 acres including terrestrial and marine environments. These islands formed millions of years ago through volcanic activity, resulting in distinctive geological features such as caves, arches, and the famous Hidden Beach (Playa del Amor), known for its large crater-like opening allowing sunlight to filter through. The park is a biodiversity hotspot home to diverse marine life including coral reefs, manta rays, tropical fish, humpback whales, and sea turtles. On land, seabirds such as blue-footed boobies and frigatebirds nest in the protected terrain. Popular activities include snorkeling, scuba diving, kayaking, wildlife watching, and hiking short trails around the islands. Due to its ecological sensitivity, visitor numbers are strictly controlled through permits and guided tours. The park is a favorite destination for nature lovers and adventure seekers alike, offering clear turquoise waters and opportunities to explore pristine habitats in a relatively small area. Its unique combination of marine and terrestrial features makes it one of Mexico’s most intriguing and valuable protected natural areas.
