Tour Highlights

  • Swim the stunning Baja peninsula, alongside sea lions and other incredible marine life in warm, clear waters

  • Discover pristine beaches and isolated coves on the uninhabited island of Espiritu Santo - there's no light pollution, which makes for fantastic stargazing!

  • Camp in style in a UNESCO protected area of unspoilt natural beauty - a birder's paradise, which is home to blue-footed booby, frigate, cormorant, pelican, red tailed hawks, hummingbirds...

  • Relax at the end of each day with cocktails, freshly-cooked meals and truly spectacular island sunsets

Explore this unique peninsula with open turquoise waters, incredible marine life and warm sunsets over the bay in Baja. Water temperatures reach up to around 26°C, offering perfect conditions for a late-season getaway to discover the unspoilt beauty of one of Mexico’s natural wonders. This is a birder's paradise as well (look out for blue-footed booby, frigate, cormorant, pelican, red tailed hawks, hummingbirds) with terrestrial animals, like ring tail cats, feral goats and the exceedingly rare black jackrabbit.

We start with a comfortable hotel night then head to the white sand beaches and dramatic cliff faces to the countless hidden bays that we’ll explore throughout the week – this is a swimming adventure like no other. The area is part of the UNESCO-protected Biosphere Reserve and offers the opportunity to discover this pristine natural environment.

Based on the uninhabited island of Espiritu Santo - there's no light pollution, which makes for fantastic stargazing - our base camps are located right on the beach, just a few steps from the inviting waters we’ll spend our days exploring. The camp is completely ‘off the grid’ and includes tents with camp beds and solar heated showers. It also offers kayaks and stand-up paddle boards which can be borrowed for your own use between our scheduled swims.

Our camp food is prepared by our very own chef and is al fresco then watch the sun go down at the end of each unforgettable day. Your last night is back at the hotel with a farewell dinner.

Who is this trip for?

This trip is designed for swimmers who are looking for a remote escape from everyday life and experience a combination of coastal swims, crossings, and circumnavigations. Guests should be comfortable being ‘off the grid’ throughout the duration of the trip, with no access to Wi-Fi or mobile reception on the island.

Swimmers should also have a basic understanding of open water swimming and be capable of completing the average swim distance of around 3km prior to the start of the trip. The average daily swim distance is around 6km (split over a minimum of two swims).

We have given this trip a ‘Moderate’ grading. Most swimmers comfortable in the open water will be able to take part and enjoy one of these trips.

After a welcome meeting and drink, you’ll have a chance to pick up any extras that you might need for the week ahead before an optional group dinner.

Day 2

After meeting in the hotel lobby early in the morning, we set off on our boat for the first swim and then on to our beachfront camp on Espiritu Santo Island. Once there, we have a chance to get set up for the week, including a brief camp orientation, followed by lunch. After lunch, you have some free time to explore the camp, kayak or have a siesta before a swim along the shoreline to neighbouring Ensenada el Mezteno. At the end of the first day on Isla Espiritu Santo, we enjoy a beautiful sunset over the Sea of Cortez while our very own chef prepares our first delicious dinner on the island.

Day 3

We start the morning with a swim in the beautiful Bahia San Gabriel (former home of the pearl beds made famous by John Steinbeck in “The Pearl”) where we swim directly past a breeding ground of magnificent frigate birds.

After lunch, we head to Las Calaveritas for our second swim of the day which takes us all the way back to base camp. Once we arrive, the rest of the afternoon is yours to enjoy before settling in for an evening cocktail as the sun dips below the horizon once again.

Day 4

We start off the day with a hike from Ensenada el Embudo to a dramatic vantage point which offers a gorgeous view of Isla Partida. The walk takes approximately 30 minutes each way. Our first swim of the day will begin at El Erizoso Punto, where we’ll swim from point to point to point, ending at Ensenada del Raza. Back at base camp we enjoy a wonderful lunch before setting off for our afternoon crossing from Isla Espiritu Santo to the sister island of Isla Partida. On our way back to camp, there may be time for some snorkelling off El Cardoncito.

Day 5

This morning we circumnavigate Isla Ballena. The incredible water quality here is clear enough to spot the many beautiful types of fish that play in the underwater rocks and nooks.

After lunch, it’s time to swim along the dramatic bluffs in Ensenada el Cardoncito. Along the way, you’ll swim over an abandoned pearl farm and end at a gorgeous sandy beach. As always, our day finishes with another delicious local dinner and a chance to relax and soak in the atmosphere of the island paradise.

Day 6

This morning we swim in the long bay of Ensenada el Cardonal, a bowl-shaped cove of rocky red outcrops. We then make our way to Los Islotes, home to a colony of friendly and curious sea lions. After having the chance to swim and snorkel with these amazing creatures, we’ll make our way back to base camp for lunch. We then head to the beautiful Ensenada Grande for our final afternoon swim. Our last night is back at our hotel in La Paz and includes a farewell dinner and the chance to enjoy an evening enjoying la Paz.

Day 7

After a great week of swimming, we’ve got time for a last morning swim. Following our swim and breakfast we say goodbye to the Sea of Cortez.

Travel Advice

For more information on any of the following sections please visit the Travel Advice page of our website.

Money, Extra Expenses and Tipping

You will need to bring enough cash to cover hotel environmental bed tax which is MXD$33.68 for the nights in the hotel. Please ensure you have the correct amount to avoid the need for change. You should bring extra money with you to cover dinner on Day 1, souvenirs, and your time in La Paz. The local currency is the Mexican Peso. SwimTrek include the National Park fee in the cost of your holiday.

In some countries tipping (gratuities) is not part of the culture. In others, it has become an expected norm. We believe that tipping is done entirely at your discretion. If you have been provided with excellent service, it may be something you wish to do. Your SwimTrek guides can advise on local norms for service providers like boat crew, waiters, or taxis. Nothing is expected for your SwimTrek guides, but many groups like to present something to the guides at the end of the trip.

Responsible Travel

SwimTrek is conscious of the importance of protecting the world’s natural wonders. We are acutely aware of our responsibility to not only take care of the natural environments which we are lucky enough to explore, but also to educate our guests about the importance of conservation efforts and responsible tourism. It’s for this reason that we have worked so closely with our partners to ensure that our trips are conducted in the most responsible and sustainable way possible, working tirelessly to minimise the impact of our presence on local marine life and the natural habitat.

For more information, please visit our Responsible Travel page on the website.

Passports and Visas

Non-residents of Mexico require a full passport to enter the country, which should be valid for six months beyond the expected length of stay. Citizens of all EU member states, the US, Canada, the UK, Australia, and New Zealand will not require a visa but will be required to fill out an immigration form to enter Mexico as a tourist for a time period of less than 180 days. Please note that visa regulations are subject to change and we advise that you check your own visa requirements prior to travel.

Travel Insurance

We consider comprehensive travel insurance to be essential, and we strongly recommend that you purchase insurance which includes, but is not limited to, cover for illness, accident, emergency repatriation, ambulance, air ambulance, helicopter rescue services, cancellation, lost luggage and delays. Your travel insurance should also cover you for open water swimming and any other activity listed in your trip itinerary (including races and competitions, where applicable). Please read your policy details carefully and remember to take them with you on your trip for your own reference. For further information about travel insurance, please visit: Travel Insurance page on the website.

At the Welcome meeting our local partners will collect details of your travel insurance including company/insurance provider, policy number, and date of expiry they will also require all guests to sign a standard liability release.

Here at SwimTrek we pride ourselves on our focus on safety and the well-being of all our guests. As we operate in some beautiful and remote locations medical facilities are not always easily accessible. SwimTrek Guides, and many staff working for our local partners, are first aid trained. However we ask that you read our Travel Health page to ensure that you are informed about general Travel and Swim Health precautions.

  • We've done this SwimTrek twice now and could see doing it again! The water, the geography, the sea-lions and the sunsets do not disappoint. Magical.

    Christina C, USA - 2022
  • A magical experience that transcends the actual sport of open-water swimming!

    Jennifer K, USA - 2022
  • Baja Isla Espíritu was in equal parts empowering, relaxing, interesting and enchanting. Pack light and get ready for a magical, unplugged week of challenging swims, highly supported beach camping, terrific local food, beautiful sea life and stunning vistas. This trip was easy for a solo swimmer. You can engage with the group or find solitude on the beach or under the stars. I spent the entire week barefoot. We had a great range of swimming speeds and the guides made sure we all got correct level of challenge.

    Julia R, USA - 2022
  • Before my trip, one comment that stood out to me on the Swim Trek website was that going on a swim adventure once a year is non-negotiable. I understand now why that's the case. I most certainly now believe the same thing! I had one of the best weeks of my life on the Baja Mexico trip in all aspects - great swimming, great people, and great off the grid adventure! Thank you to Jamie and the team.
