Bahía de Banderas is one of Mexico's most rewarding dive destinations, with warm water, dramatic underwater pinnacles, playful sea lions and seasonal visits from giant mantas and humpback whales. Whether you are taking your very first breath underwater or logging your hundredth dive, Puerto Vallarta has a school to match your ambitions. Here are ten of the best diving schools around the bay.
1. Banderas Bay Divers
A long-running favorite with PADI-certified instructors, this school is known for small groups and patient teaching. They run regular trips to Los Arcos and the Marietas, and their open-water courses are a smart pick for nervous first-timers.
2. Vallarta Sub Aqua
Centrally located and family-run, this operation focuses on personalized service. Their discover-scuba sessions in calm, shallow water are a gentle introduction before you commit to a full certification.
3. Pacific Scuba Divers
This crew has a reputation for reaching the bay's more remote sites, including the deeper pinnacles off Corbeteña, where big pelagics gather. Best suited to certified divers looking for adventure.
4. Chico's Dive Shop
One of the oldest names on the Malecón, Chico's combines a convenient downtown location with decades of local knowledge. A reliable choice for snorkel-and-dive combo days.
5. Ocean Quest Divers
Small, eco-minded and detail-oriented, Ocean Quest emphasizes marine conservation and responsible diving practices. Their guides are great at spotting camouflaged critters most people swim right past.
6. Vallarta Adventures Diving
The diving arm of a major local tour company, this option pairs professional logistics with comfortable boats. Ideal if you want a polished, all-inclusive day on the water.
7. Dive Banderas
A boutique operation that limits group sizes and prioritizes one-on-one attention. Popular with travelers refreshing rusty skills through a quick scuba review.
8. Scuba Mike's
Known for friendly, no-pressure instruction, Scuba Mike's is a favorite for families and mixed-ability groups who want a relaxed pace.
9. Mr. Cricket Diving
Based in the bay's north shore near Punta de Mita, this school offers easy access to clear-water reefs and is well-positioned for Marietas trips.
10. Punta Mita Expeditions
If you are staying on the Riviera Nayarit side, this outfit specializes in the northern bay's dive sites and combines diving with surf and sailing excursions.
Tips Before You Dive
Always confirm your instructor holds a current certification and that the school carries oxygen and first-aid equipment on board. Bring reef-safe sunscreen and never dive within 24 hours of flying. For more ways to explore the water, see our guides to tours and beaches.

Water temperatures range from the low 70s°F in winter to the mid 80s°F in summer. A shorty or 3mm wetsuit is comfortable for most of the year.
Where are the best dive sites?
Los Arcos Marine Park and the Marietas Islands are the most popular. Experienced divers head farther out to Corbeteña and El Morro for larger marine life.
