Planning a trip to Puerto Vallarta and want to explore beyond the city streets? The Marietas Island Adventure on a comfortable catamaran might just be what you’re after. This five-hour tour promises a mix of wildlife encounters, snorkeling, scenic cruising, and relaxing onboard fun—all in the company of knowledgeable guides. We’ve looked into what makes this tour popular, and here’s what you should know before booking.
What we love about this experience? First, it’s the chance to see humpback whales (in season) and playful dolphins—wildlife lovers will find this especially rewarding. Second, the snorkel stop at the protected marine park is a chance to swim among colorful fish and corals in crystal-clear waters. Third, the open bar and hot lunch make the trip feel more like a vacation than just an excursion.
A potential consideration? The marine park conservation fee and marina entrance fee are additional costs, so it’s good to factor those in. Also, the tour isn’t suitable for children under 6 or pregnant women, so it’s not ideal for families with very young kids or some pregnant travelers.
Who’s this tour perfect for? It’s ideal for adventure seekers, wildlife enthusiasts, and those who want a relaxed day on the water with some snorkeling and wildlife spotting. If you’re after an active, fun-filled day with friends or family (over 6 years old), this one’s worth considering.
