About
Visible from the beaches of Puerto Vallarta are three towering granite islands, home to the Parque Nacional Marino Los Arcos de Mismaloya.
This protected marine park was formed in 1984 and features Roca de Los Arcos (Arch Rock), Roca de la Tortuga (Turtle Rock), and Roca del Diablo (Devil Rock). The name of the latter was earned for the cliffs on one side resembling a devilish figure.
What makes visiting awe-inspiring is realizing that centuries of wave and wind erosion created these impressive landmarks. Beyond its remarkable appearance, the area holds historical significance. Mismaloya’s connection with Hollywood in the 1960s—thanks to the filming of The Night of the Iguana—propelled it and the neighboring waters into international fame. This recognition made Parque Los Arcos a key vacation destination in Mexico.
Aside from the three islands, the park serves as a sanctuary for marine life and a home to vibrant coral reefs. The crystal-clear waters, diverse ecosystems, and towering cliffs make it a favorite spot for snorkeling, scuba diving, and boating.
The conservation efforts ensure that sea turtles, manta rays, and vibrant tropical fish thrive in this ecologically critical habitat.
Visiting Los Arcos Marine Park is a standout attraction at Puerto Vallarta, offering something for everyone.
Parque Nacional Marino Los Arcos de Mismaloya: Fun Facts & Cool Features
A breathtaking feature of the park is the clear water that reveals an underwater wonderland. Here, you’ll find coral reefs hosting hundreds of marine species. Additionally, the waters are calm, which adds to the allure and makes exploring relatively safe. For these reasons, snorkeling and scuba diving are popular at Los Arcos.
A surreal phenomenon is the underwater tunnels and caves, considered one of the Pacific’s most outstanding geological displays. Diving enthusiasts flock here to explore tunnels like Devil’s Canyon and experience stunning visuals and an unmatched thrill.
A fun fact is that Los Arcos is known for its dramatic drop-offs. The underwater floor descends from 30 feet to 1,600 feet, making it one of the deepest points in Banderas Bay. Such depths attract larger marine life such as dolphins, whales, and bioluminescent plankton during certain seasons.
But visiting isn’t just about the water. Nature lovers will find visiting exhilarating as it is a birdwatcher’s paradise. From blue-footed boobies nesting on the rocks to pelicans soaring overhead, the islands provide the perfect vantage points for various birds.
Adding to its charm is its status as a top destination for eco-tourism activities, such as kayaking, paddleboarding, and sustainable boat tours.
For the ultimate adventure, combine a visit to Los Arcos with a trip to the Marieta Islands. After your adventures, refuel with delicious Mexican cuisine at nearby eateries like Restaurant María Cuquita and Mismaloya Grill.
With its colorful marine life, captivating underwater landscapes, and fascinating wildlife, Parque Nacional Marino Los Arcos is an adventure that will leave its mark on your Puerto Vallarta vacation.
