Swimming Vacation – Loreto National Marine Park

Discover the magnificent Loreto Bay National Marine Park in southern Baja California and swim with a wide range of wildlife. The Sea of Cortez is the home to some incredible marine life which makes this trip such a special journey. Jacques Cousteau named these waters ''The Aquarium of the World'' for a reason. Located in the desert next to the Sierra de la Giganta mountains and the azure-blue sea, this area offers an all year round adventure destination. Loreto Bay is part of the UNESCO World Heritage site and it is a protected natural area in Mexico.

Day 01
Arrival day to Loreto town, Baja, Mexico. Meet at the hotel lobby for a group meeting and trip briefing. We get to know each other and your guides explain the plan for the week ahead.


Day 02
We start our first day by taking a 30 min boat drive to the north-western side of Carmen island where we do a short acclimatization swim and distribute our swimming caps. Everyone gets comfortable in the warm Sea of Cortez. For our first proper swim, we keep it coastal in the bay of Balandra for about 2 km. Lunch onshore in the bay.

Before our second swim your guides film your stroke in the clear water. Later on, we sit down and analyse your swimming stroke supported by some tips on how to improve your technique in open water. The second swim takes us from Puerto Balandra further south along Carmen island. Boat drive back to Loreto.


Day 03
Today we are heading north to visit Coronado Island. There is no day here without sea lions, dolphins and several other marine species. We enjoy our morning swim in the eastern part of the island where we finish the swim next to the sea lion colony. Lunch break in the Candeleros bay (Ensenada Blanca). After lunch, we do a short walk up the hill to soak up the amazing view from this former volcanic island. There are usually hundreds of pelican birds around us which make our walk even more adventurous.

Second swim in the Los Metales bay on the eastern side of the island. The waters here are shallow and we enjoy looking at thousands of fish underneath. We also hope to see a bunch of dolphins around us.


Day 04
Today we are heading south to the magical Danzante island. Renowned French explorer Jacques Cousteau calls the Danzante Bay and this area “the Aquarium of the World” because there are over 5,000 species of sea creatures. Our first swim is on the southern part of the island where we stop at the La Ventana window point. Our swim is anything but boring as we look up the high cliffs of Danzante island. We finish our morning swim at the El Submarine little rock where we are picked up by our escort boats. Lunch at Honeymoon cove

Before our second swim, we hike up to the plateau to get the best view of the Loreto National Park. Second swim from Honeymoon bay towards the northern part of the island. Here we usually spot thousands of sardines as they congregate around this bay. 


Day 05
We are heading back to the southern part of Carmen island to explore further stunning spots. The first swim takes us from Punta Colorada to La Pared point. We swim alongside the shallow and rocky seabed in the warm turquoise water. We see rich marine life all around us including manta rays, stingrays, starfish, and hundreds of other fish species.

Lunch break at the Bahamitas Beach. After we eat lunch, we rest and then continue swimming to the furthest southern point of Carmen island (Punta Baja). The amazing turquoise water makes you not want to leave! Drive back to Loreto.

Day 06
Our final full day swimming out has arrived. Our boats take us across to the northern side of Carmen island where we swim in this unspoilt nature. We swim from Punta Tintorera to La Vaca bay where we stop for our lunch break. This is the time when you can ask our guides for any further swimming tips or drills and hopefully, by now you have learnt and experienced the best of open water swimming in this beautiful environment.

For the second swim, we travel to Punta Labos and swim outside on the eastern side of Carmen island. Afternoon drive back to Loreto harbour. Final group dinner out.


Day 07
Departure day. After such an amazing week you have met some great new friends and now it is time to say goodbye.

Group size
Up to 16 guests (unless agreed differently), plus guides (or kayakers) and boat captains.


Walking Conditions
To enjoy your walks on the islands, we advise you to bring comfortable light walking shoes for summer temperatures. Aqua shoes or sandals are recommended to have when we are stepping in and out of the boats on the beaches.

Essential Equipment
In addition to normal items, we recommend the following:
– 2 pairs of swimming costumes,
– 2 pairs of swimming goggles, 1 clear & 1 tinted (anti-glare) recommended,
– A lightweight towel for boat practical use (changing outside),
– Sun Hat, Sunglasses, Suncream,
– Small Daypack,
– Waterproof sun cream and jacket / fleece / windstopper,
– Walking shoes and sandals or aqua shoes,
– Lightweight and light-colored clothing for outdoor environments.

We provide silicone swim caps and limited safety tow floats for better visibility! If your swimming depends on other items (wetsuit, rash vest, fins, designed swim cap), please bring them with you. Please also bring your own drinking water bottle (marked with your name) for swims, walks, and time on the boat. It is very important to drink enough water and other fluids throughout the whole trip. Use bottled water in Mexico including at the hotel. There is a small shop right at the corner. Our boats have large flasks to refill your drinking bottles while out at sea.

Swimming awareness and itinerary changes
Your safety is of utmost importance to us. In the event of adverse weather conditions (wind, storms, thunder) at any of our swimming locations on any day, we may need to adapt our itinerary for safety reasons. Our team always includes local guides who know the safest and most beautiful places to swim, so rest assured you won’t be missing out!

In the event the local port (marina) in Loreto is closed due to adverse weather (usually wind), we may take you swimming to an alternative place (sheltered bay) by van or we may go hiking to San Javier Mission which is the best preserved of all the Missions in the Californias. The trip takes us through the small valley oasis in the Sierra de la Giganta (Mountains of giant women). Either activity is a wonderful experience in this area.

Swimming in the sea is a unique experience, but you may come across certain life such as fish, jellyfish, or sea lice. The water in the sea can be deep and the bottom cannot always be seen. If you suffer from Anaphylaxis or any other allergic reactions, it is important to inform us at the time of booking. Also, please bring with you any personal medical supplies you may need while on the trip.

“Dolphins were jumping up and down not just once but literally almost every day during our trip. So special! We also got to visit seals and even blue-footed boobies that I thought I would only see once in my life (when I visited Galapagos), but, surprisingly here they were, too! Great way to swim in warm open water with no crowds and see amazing marine life!”
