Overview

Rock reefs, volcanic islands, and winter whales on Mexico's Pacific bay

Puerto Vallarta and the Bahia de Banderas wrap Mexico's central Pacific coast with easy day-boat access to rock reefs, caverns, and offshore pinnacles. Divers base in Puerto Vallarta, Nuevo Vallarta, or Punta Mita, then hop to Los Arcos for shallow training dives and nudibranch hunting, push farther to El Morro for caves and pelagic chances, or head north to Islas Marietas for volcanic tunnels and reef fish. Winter brings humpback whales in the bay, while summer and early fall deliver the warmest water and often the clearest visibility. Topside, you get a walkable Malecon, jungle day trips, surf towns like Sayulita, and sunset sea turtle releases. The region rewards early starts, flexible planning around rainy season squalls, and respect for protected-area rules in Marietas and Los Arcos.

What Makes It Special

  • Two signature protected areas

    Pair Los Arcos' rock formations with Islas Marietas' regulated national-park style rules for a full-spectrum bay itinerary.

  • Seasonal variety

    Winter brings humpback whales and drier weather. Summer and early fall bring the warmest water and frequent best-visibility windows.

  • Mixed-group friendly

    Divers, snorkelers, and non-divers can share the same boat days and regroup easily for food, sunsets, and day trips in town.

  • Adventure within reach

    Short hops for beginners in sheltered coves, plus condition-dependent pinnacles like El Morro for advanced divers.
