This dive site, Los Arcos National Park, is a renowned dive site located in the southern part of Banderas Bay, Puerto Vallarta, Mexico. Formed by a cluster of striking granite islands, this underwater realm offers a dynamic environment with diverse topography including sites like El Bajo and the intriguing Devil’s Canyon. Its natural beauty and accessibility make it a top destination for divers exploring the Pacific coast of Mexico.
The vibrant marine ecosystem at Los Arcos is home to a rich array of semi-tropical Pacific species. Divers and snorkelers can expect encounters with fascinating creatures such as octopuses, lobsters, and a variety of eels. The site is also known for larger pelagic visitors, including graceful eagle rays and majestic manta rays. Colorful reef inhabitants like butterflyfish, angelfish, and damselfish further enhance the biodiversity of this bustling underwater world.
The best time to visit Los Arcos for optimal diving conditions is generally during the dry season, from November to May, when water temperatures are comfortable and visibility is typically at its peak. This site is highly suitable for both scuba divers of all levels due to its varied depths, and also excellent for snorkelers and freedivers who can explore the shallower areas around the granite formations and witness abundant marine life close to the surface.
