Discover the breathtaking marine life of Marietas Islands with this full-day tour featuring snorkeling, kayaking, meals, and an open bar—perfect for adventurous travelers.
Venturing to the Marietas Islands on a full-day tour offers an exciting blend of natural beauty and marine adventure. This experience isn’t just about ticking off a popular destination but about truly engaging with the environment, guided by knowledgeable hosts who make sure you get the most out of your day. If you’re craving an active day exploring caves, snorkeling vibrant waters, and spotting whales or dolphins, this tour could be just the ticket.
What we love about this experience is how it combines wild marine encounters with the comforts of a well-organized day—meals included and an open bar to loosen up after some snorkeling. The professional guidance makes it accessible for all skill levels, and the chance to see humpback whales (from December to March) is a highlight for wildlife enthusiasts.
One potential consideration is the cost of the port fee ($30 MXN) and the optional conservation bracelet ($110 MXN), which can seem like an extra expense. Still, most would agree that the overall value, given the boat ride, meals, and activities, makes it worthwhile.
This tour is ideal for active travelers who enjoy marine environments, are comfortable in group settings, and appreciate a mix of adventure and relaxation. If you’re looking for a day filled with scenic views, wildlife sightings, and water-based fun, this full-day outing hits the mark.


The Marieta Islands tour promises a full day of marine discovery, and it generally starts early, with a meeting point at Puerto drinks & snacks on Francisco Medina Ascencio Boulevard at 8:15 a.m. and departure at 9:00 a.m. This schedule suits those who prefer to make the most of daylight hours—it’s a morning outing that wraps up roughly six hours later, returning to the pier by early afternoon.
The journey begins with a scenic boat ride that offers a good chance to settle into the day, soak up the views, and get a sense of the islands’ rugged beauty. The boat itself is a comfortable platform for the day’s activities—large enough to accommodate up to 80 travelers but intimate enough to feel like an adventure with friends.

One of the biggest draws here is marine wildlife. We love how the tour emphasizes encounters with dolphins and the colorful schools of fish that thrive in the waters. Several reviews mention the thrill of seeing dolphins leap alongside the boat and the vibrant underwater scene when snorkeling.
From December to March, the possibility of humpback whales makes this trip even more special. Witnessing these gentle giants breach or tail slap is a bucket-list moment that adds a layer of awe to the experience. While whale sightings depend on the season and luck, the chances are good enough to keep visitors excited.
The natural caves at the islands form a core part of the tour’s appeal. These formations are fascinating, carved over centuries by the ocean, and they provide perfect photo opportunities. We’ve heard from travelers that exploring these caves gives a real sense of discovery, especially when combined with underwater snorkeling.
Snorkeling gear—fins, vests, snorkels—is included, making it easy for first-timers or casual swimmers to join in. The crystal-clear waters reveal a lively underwater world with many colorful fish. Kayaking is also part of the package, offering a different perspective and a peaceful way to explore the coastline.
We appreciate that the tour includes breakfast and lunch, which means you won’t need to pack your own meals. The food is generally well-received, giving a much-needed fuel-up after water activities. The open bar is a nice touch, allowing travelers to unwind with drinks after the exertion or during the cruise back to shore.
A word of note: while the included drinks add value, some reviews suggest that the atmosphere is casual and relaxed, perfect for enjoying the scenery rather than partying.
