The boat slips away from Puerto Vallarta's south bay and the city recedes into a line of roofs while the Pacific opens. Wind pulls at your hat, gulls wheel above, and the limestone arches of Los Arcos rise from the water—rock faces scored by waves and home to caves that dare you to peer inside.

The boat slips away from Puerto Vallarta's south bay and the city recedes into a line of roofs while the Pacific opens. Wind pulls at your hat, gulls wheel above, and the limestone arches of Los Arcos rise from the water—rock faces scored by waves and home to caves that dare you to peer inside.
Los Arcos de Mismaloya is a protected marine park where volcanic bedrock and coral outcrops create pockets of habitat for reef fish, rays, and sea turtles. The area gained wider attention in the 1960s when the nearby village of Mismaloya hosted film crews, but its significance long predates tourism: local fishing communities relied on these reefs for generations.
On this 2½-hour excursion you’ll cruise along South Bay, stop at the arches, and slip into clear water with a guide. Expect short swims between rocky reefs and sheltered caves, life jackets and snorkel gear provided, and a chance to spot parrotfish, angelfish, and occasionally larger visitors like rays or turtles.
Practical notes: wear reef-safe sunscreen, a snug mask, and water shoes for rocky landings. Mornings tend to be calmer for visibility; tours include bottled water and a light sandwich. The marine park is actively managed—keep a respectful distance from corals and wildlife and follow your guide’s instructions to reduce impact.
This outing is an accessible, scenic introduction to Banderas Bay’s underwater life—short, vivid, and best timed for calm seas and clear light.
