Cruise Lines:

The Sea of Cortez is an often-overlooked destination by UK travellers. Cradled between the barren Baja California Peninsula and the Mexican mainland, at first glance you might assume that the windswept coastline offers little more than rugged desert beauty. But dive under the surface of these waters and you'll discover an extraordinary wealth of wildlife that has earned the Sea of Cortez UNESCO World Heritage Site status. These are the best Sea of Cortez cruises to book now for an unforgettable adventure...

Famed for its huge numbers of dolphins, sea turtles, blue whales, gray whales, orca, humpback, pilot and fin whales, whale sharks, manta rays and sea lions, it's no wonder Jacques Cousteau described the Sea of Cortez as 'the world's aquarium'.

Exploring by water is the best way to discover the region, but only a couple of expedition cruise lines currently operate here. We've put together a short guide to the best options available…

1. National Geographic-Lindblad Expeditions

One of the best expedition operators in the world, National Geographic-Lindblad Expeditions have a reputation for offering more aboard, such as a certified photo instructor on every Baja California departure to assist you with camera settings, the basic elements of framing, composition and lighting and general tips to ensure you go home with fantastic photos. Lindblad regularly operate three ships in the region between November and April, on a choice of six itineraries ranging from four to 14 nights including a Loreto round-trip, spending seven days sailing amongst the islands of the Sea of Cortez. Highlights include the secluded coves and golden beaches of Isla San Jose; Los Islotes, where you can swim with sea lions; and Isla San Francisco, all steep red bluffs, sweeping desert beach and colourful sea life.

You'll be sailing on the 100-guest National Geographic Venture, which launched in 2019. The ship has twin expedition craft landing platforms, allowing quick access to the Zodiacs to maximise time off the ship, whilst the bow has a uniquely tiered viewing system so you won't miss a thing. No matter which itinerary you choose, all of the Lindblad ships operating here have kayaks, paddleboards, snorkelling gear, hydrophones and multiple underwater cameras, and with a range of sailings from a number of departure points, there's sure to be an itinerary that suits.

2. Ponant

French line Ponant is the perfect choice for adventurous travellers who like luxury, travelling in the company of an experienced, enthusiastic expedition team including naturalists, historians and geologists.

One of the line's Explorer Yachts Le Bellot visits the Sea of Cortez in 2027 with a fabulous round-trip itinerary from Cabo San Lucas on a 10-night voyage beginning on 10th Febuary which begins by sailing to Magdalena Bay, famed for the gray whales that visit to give birth and raise their calves here in February and March, and then focuses on the more southerly area of the Sea of Cortez, with a flexible itinerary to allow for spontaneity. This gives you the best chance of experiencing spectacular wildlife encounters, from vast pods of dolphins to mass gathering of mobula rays, which are known for leaping out of the water.

3. UnCruise Adventures

UnCruise Adventures specialise in small ships exploring off the beaten track, giving inquisitive travellers who love wilderness, wildlife and exploration an unrushed and uncrowded opportunity to experience a holiday with a difference. As well as offering all the expedition activity you'd expect, including snorkelling, kayaking, stand-up paddle-boarding, whale watching and hiking, UnCruise's relaxed and informal approach is also apparent in the evening beach party included on each Sea of Cortez itinerary, celebrating the night sky with a bonfire, warm beverages and a constellation lesson.

UnCruise's Sea of Cortez voyages are on board the Safari Voyager, which operates a regular 7-night itinerary between January and April, accommodating a maximum of 66 guests. A bow viewing area and sun deck means space for wildlife viewing, and there's a kayak launch platform for ease. A basic yet comfortable vessel, she's equipped with a bow-mounted underwater camera, paddleboards, Zodiacs and snorkel gear, perfect for exploring both above and below the water. Your itinerary includes plenty of snorkelling, swimming, hiking and wildlife spotting, with calls at Bahía Agua Verde, Isla San Francisco, Isla Partida, Isla Espíritu Santo and, if the gray whales have arrived on Baja's west coast, you'll often also drive across the peninsula to Magdalena Bay. Plus, UnCruise have 14-night voyages inspired by John Steinbeck's "Log from the Sea of Cortez," with the chance to spot marine life at historic sites such as Punta Marcial, snorkelling near Isla Catalina, and whale watching between Isla Catalina and Santa Rosalia as well as a magical night of star-gazing.
