Banderas Bay, Puerto Vallarta,
Description: BAHÍA DE BANDERAS. Even if you're not into snorkeling, Los Arcos is a natural attraction that you see from anywhere along the coast of Banderas Bay. Snorkeling is fabulous, with the opportunity to see marine life such as angelfish, damsels, puffer fish and even the occasional manta ray. The natural formations are a landmark and have been declared a natural marine park. Visit them by boat but keep off the rocky slopes that are such a haven for birds. Even if you don't snorkel, you can't help but see the schools of fish right below the surface of the water. Swim through the natural arches that form an above-water cave. Numerous companies offer snorkeling trips or stop to visit Los Arcos en route to the south coast.
