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 an island paradise with open turquoise waters, incredible marine life, and warm sunsets over the bay on this unique and unforgettable swimming holiday in Baja, Mexico. With water temperatures of around 26°C, this late-season getaway provides the perfect opportunity to discover the unspoilt beauty of one of Mexico’s natural wonders.

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 a pristine natural environment.

Based on the uninhabited island of Espiritu Santo, our 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 eaten al fresco before we watch the sun go down at the end of each unforgettable day. Your last night is spent back at the hotel for a farewell dinner so you can reflect on the past week’s adventures.

Trip Schedule

Start Point: Hotel Catedral, La Paz

Start Time: 16:00 on Day 1

Day 1

After arriving into La Paz, Baja you will be able to check-in into the Hotel Catedral. We then meet for a short safety briefing and an acclimatisation swim before returning to the hotel. 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 head 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

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.

We return to the new base camp and 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. The local currency is the Mexican Peso. SwimTrek include the National Park fee in the cost of your holiday.

You should bring extra money with you to cover items such as meals not already included in your package, drinks, entertainment, souvenirs, etc.

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 own 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 it is important 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.

  • 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.
