The boat slips away from Puerto Vallarta’s shoreline and the city’s hum thins to wind and surf. A ring of jagged rock—Los Arcos—raises from the bay: dark, arching islets that break waves into foamy edges and shelter clear, teeming water. Under Thalia’s guidance, the surface becomes a window; schools of parrotfish and snapper wheel like living brushstrokes around rocky outcrops, and a reef-streak of sand hints at sleeping rays.

The boat slips away from Puerto Vallarta’s shoreline and the city’s hum thins to wind and surf. A ring of jagged rock—Los Arcos—raises from the bay: dark, arching islets that break waves into foamy edges and shelter clear, teeming water. Under Thalia’s guidance, the surface becomes a window; schools of parrotfish and snapper wheel like living brushstrokes around rocky outcrops, and a reef-streak of sand hints at sleeping rays.
Los Arcos is part of a protected marine area carved from ancient lava and marine uplift, its arches shaped by centuries of sea and weather. The adjacent Mismaloya beach carries a bit of film history—John Huston’s Night of the Iguana shot here—while local fishers have navigated these waters for generations. The park’s rules limit numbers and boat traffic to protect corals and resident wildlife, so a private trip feels intimate and purposeful.
Expect two snorkel stops in calm coves, a short safety briefing, and interpretive commentary on species, reef health, and local conservation. Water temps are warm most of the year; visibility varies with tides and swell. Practicalities: the excursion lasts about four hours, gear is provided, and the guide is a certified lifeguard and marine biologist.
Pack reef‑safe sunscreen, a light sun layer, and a waterproof camera. Plan mornings for the calmest water and highest visibility. Stay close to the guide, avoid touching coral, and bring a sense of curiosity—the clear water here rewards steady observation more than speed.
