Tour Highlights
Share your swims with a variety of local wildlife in the Loreto National Marine Park, including dolphins, sea lions, tropical fish and rays.
Search for sea stars and turtles near the sandy beaches of southern Coronado – the closest island to Loreto. Then swim with a backdrop of lava rocks and local sea lions, exploring La Grimas (‘the tears’).
Stay in the coastal town of Loreto, where the old and new world meet. Roam cobbled streets, visit charming outdoor cafés and relax on the waterfront to watch those famous Baja sunsets.
Follow John Steinbeck's adventures in the Sea of Cortez and enjoy coastal swims among nearby islands: Isla Coronado, Isla Carmen and Isla Danzante.
They call it the ‘aquarium of the world’ for a reason – the shimmering Sea of Cortez is a paradise for divers and swimmers alike!
During our trip we are based in the coastal town of Loreto, where the old and new world collide. You’ll have time to wander cobbled streets, relax at outdoor cafés with a craft beer in hand and roam a malécon along the waterfront. We will also meet the local marine life (dolphins, sea lions, tropical fish and rays) as we swim through the National Marine Park. Then, in the winter months, whales migrate through these waters to give birth in tropical waters.
Loreta was the first Spanish settlement in the Baja Peninsula and it serves as an ideal base from which to launch adventures out to sea. Across a series of exciting swims, you will uncover the natural treasures of three islands, scattered just off the coast: Isla Coronado, Isla Carmen and Isla Danzante.
Nobel Prize winner John Steinbeck spent six weeks chartering a sardine boat and sailing this sea. He later wrote The Log From The Sea Of Cortez and described a longing to go back after his journey’s end: ‘Since we have returned, there is always in the backs of our minds the positive drive to go back again’.
We hope our SwimTrekkers will feel something similar after their time in the sunlit Sea of Cortez.
If you would like to explore this part of the world, but are looking for slightly shorter swimming distances, please check out our Sea of Cortez Short Swims trip.
