With coastline on the Pacific, Sea of Cortez, Gulf of Mexico, and Caribbean Sea, it’s no surprise that the scuba diving in Mexico is simply outstanding.
Liveaboards based in this diverse country typically focus on either—or both—of two destinations: the incomparable Revillagigedo Islands, including world-famous Socorro, or the Sea of Cortez, aptly called by Jacques Cousteau “the world’s aquarium.” Decide first what you’d like to see and when you’d like to travel, as most of the following boats alternate itineraries throughout the year.
Trips to Socorro depart from Cabo San Lucas, only 235 nautical miles away. The dive season here runs from November through May, and the only way to access this remote area is via liveaboard.
Here you’ll almost certainly see the elegant manta rays the archipelago is known for and, depending on when you book, you may find yourself underwater with dolphins, humpback whales, hammerheads, and whale sharks as well. Silky sharks, Galapagos sharks, whitetip reef sharks and silvertips are present all year.
Trips to the Sea of Cortez truly offer something for everyone. Depending on when you visit, you may encounter thousands of mobula rays, orcas, humpbacks, sperm whales, blue whales, whale sharks, sea lions, giant pods of dolphins—this truly is the aquarium of the world. Departures take place each year from April through November, from either La Paz or Puerto Peñasco.
When it comes to liveaboards in Mexico, you’ve got your pick of boats from budget to luxurious. Trips typically last about a seven days, but you can find shorter and longer journeys as well.
Here we’ve rounded up the top boats and made it possible to sort them based on price range and length of trip.
Let’s dive into our reviews of the top nine liveaboards in Mexico.
Diving in Mexico is good all year-round. The best time to go depends on what you want to see. Visit Socorro from November to May and the Sea of Cortez from April through November.

Liveaboards in Mexico
There are two main liveaboard routes in Mexico—those that visit the Revillagigedo Archipelago and those that visit the Sea of Cortez. Although boats used to visit the great whites in Guadalupe Island, the Mexican government suspended the practice in January, 2023, and no dive boats have visited since.
Sea of Cortez trips typically depart from La Paz, while Socorro trips depart from Cabo San Lucas, so plan accordingly for your arrival and departure.
The four uninhabited Revillagigedo Islands are found 285 miles (458 km) off the Baja Peninsula and are only accessible via liveaboard. Islands include not only world-famous Socorro, but also San Benedicto, Roca Partida, and Clarion. Dives can feature strong currents and typically start at around 82 feet (25 m), so you’ll need some experience in both environments. We recommend at least 50 dives under your weight belt before visiting Socorro.
Although it takes a full 24 hours to get to Socorro from the embarkation point in Cabo San Lucas, the trip is worth it. You’ll almost certainly be treated to encounters curious mantas, plus more sharks than you’ve likely ever seen in one place—whitetip reef sharks, hammerheads, silkies, Galapagos sharks, nurse sharks, tiger sharks—the list goes on. Depending on when you visit, you may also see huge pods of dolphins or migrating humpback whales.
The Sea of Cortez, tucked in between mainland Mexico and the Baja California peninsula, is nothing short of an underwater treasure chest. Trips typically depart from April through November, though you can dive at other times of the year as well.
Marine life sightings here can include anything from passing blue whales to orcas to schools of mobula rays thousands strong. If you’re after more intimate encounters, friendly sea lions aren’t known as the “puppies of the ocean” for nothing, and they may go so far as to playfully remove your regulator from your mouth or nip a fin off your foot.
What to know about liveaboard diving in Mexico
- Socorro Island often has strong, unpredictable currents, so these liveaboards are suitable for advanced divers only.
- Due to the biosphere regulations around Socorro, divers are not allowed to use lights, gloves or knives underwater. Camera lights are allowed.
- November through May is the time to visit Socorro, when you’ll see manta rays and possibly seasonal migrators like humpbacks and whale sharks.
- Note that huge plankton blooms in Socorro can hinder visibility.
- There is a 16% tax imposed if you’re diving in Mexico, although it’s typically included in the price of your trip.
- Fly into Cabo San Lucas for your Socorro departure. From there, your liveaboard will take the 24-hour trip to Socorro.
- Fly into either La Paz or Puerto Peñasco for your trip to the Sea of Cortez—check your itinerary closely before booking.
- Although Spanish is the native language, many people speak English as well.
