What to Know Before You Dive in Vallarta

The best visibility in Banderas Bay typically runs from May through November, when the water is warmest and clearest. Always choose a school with certified instructors (PADI, SSI, or NAUI) and well-maintained equipment, and never dive within 24 hours of flying. Popular sites include Los Arcos National Marine Park and the protected Marietas Islands, where access is limited to safeguard the ecosystem. Pair your dive day with a stop at one of the area's beautiful beaches to round out the adventure.

Frequently Asked Questions

Do I need to be certified to dive in Puerto Vallarta?

No. Most dive schools offer beginner "discovery" or "resort" dives that let uncertified visitors experience scuba diving under the close supervision of a professional instructor. If you want to dive independently or go deeper, you will need a certification course, which typically takes three to four days.

What are the best dive sites in Banderas Bay?

The two standout sites are Los Arcos National Marine Park, with its dramatic underwater arches and reefs near town, and the protected Marietas Islands, famous for marine life and visibility. Both are reachable on day trips through local dive schools.

When is the best time to dive in Puerto Vallarta?

Diving is possible year-round, but water clarity and warmth peak from roughly May through November. December through April brings cooler water but also the chance to hear humpback whales singing underwater during their migration into the bay.

How much does diving cost in Puerto Vallarta?

Single guided dives and discovery experiences are quite affordable, while full PADI Open Water certification courses cost more and span several days. Prices vary by operator and whether trips include equipment, boat transport, and park fees, so always confirm what is included when booking.
