If one experience defines Huatulco, it is exploring its iconic bays from the water. The Huatulco 7 Bays Tour is, without a doubt, the most emblematic excursion on the Oaxacan Coast: a boat trip that takes you to turquoise bays, pristine beaches and corners where the jungle melts into the Pacific. Whether you are coming for the first time or are a returning traveler, this tour always has something new to discover.
Huatulco is the only destination in Mexico with an international sustainability certification, and its bays are the heart of that privileged ecosystem. Along more than 36 kilometers (about 22 miles) of protected coastline inside Huatulco National Park, nine main bays are spread out (although the classic route visits the seven most accessible ones), with more than 36 white-sand beaches, coral reefs and mangroves teeming with extraordinary marine biodiversity.
In this article you'll find everything you need to plan your bay tour: what to see at each stop, when to go, what to bring, traveler tips and the differences between the available options. Keep reading and get ready for one of the most memorable experiences of your trip.
The Bays of Huatulco: A Protected Natural Treasure
Huatulco's bay system is part of Huatulco National Park, managed by CONANP, which guarantees the protection of its marine and land ecosystems. That is no small detail: it means that when you sail these waters, you are in one of the best-preserved settings on the Mexican coastline.
The bays most often visited on the boat tour are Tangolunda, Chahué, Santa Cruz, El Órgano, El Maguey, Cacaluta and San Agustín. Each has its own character:
- Santa Cruz Bay: The tourist heart of Huatulco. Most tours set sail from here. Surrounded by restaurants, handicrafts and the main pier.
- El Órgano Bay: Small, serene and perfect for snorkeling. Its waters are remarkably clear, ideal for spotting colorful fish and coral formations.
- El Maguey Bay: A family favorite thanks to its calm waters and shaded palapas. A perfect spot to relax with a cold coconut after snorkeling.
- Cacaluta Bay: One of the wildest and most photogenic. Heart-shaped when seen from the air, it has limited access, which makes it especially special.
- San Agustín Bay: The farthest from the center, and for that very reason, the quietest. Here the jungle reaches almost to the water's edge and marine life is abundant.
- Chahué Bay: Modern and home to a marina, it is ideal for those who want to combine nature with comfort.
- Tangolunda Bay: The bay of the big resorts, with a perfect strip of sand and calm waters ideal for swimming.
According to INEGI data, Huatulco receives hundreds of thousands of visitors every year, drawn mainly by its coastal natural resources, which places it among the most important beach destinations in southeastern Mexico.
Yacht or Catamaran? Choose the Experience That Calls to You
One of the most common questions among travelers is: what is the difference between doing the tour on a yacht or on a catamaran? The answer depends on the kind of experience you want. Here is a practical comparison:
| Feature | Yacht Tour | Catamaran Tour |
|---|---|---|
| Group size | Smaller groups | Medium-sized groups |
| Stability at sea | Good | Very high (twin hull) |
| Experience on board | Intimate and exclusive | Social and lively |
| Best for | Couples, anniversaries, small groups | Families, groups of friends |
| Bays visited | A selection of the main ones | A selection of the main ones |
| Snorkeling included | Yes | Yes |
| Approximate duration | 4–6 hours | 4–6 hours |
| Best season | Year-round | Year-round |
Both options depart from the pier at Santa Cruz Bay, in the heart of Huatulco, and come with specialized local guides who know every corner of these waters.
Marine Life in the Bays: What You Can Find Underwater
Snorkeling is one of the most anticipated activities of the tour. The waters of the Oaxacan Pacific hold surprising biological richness, and Huatulco's bays are an excellent starting point for exploring it.
During the trip, especially at El Órgano and San Agustín bays, it is common to spot:
- Parrotfish, butterflyfish, surgeonfish and moray eels on the coral reefs
- Sea stars and sea urchins on the seabed
- Bottlenose dolphins, which often accompany boats out at sea
- Sea turtles (especially between August and December, during nesting season)
- In winter (November–March): occasional sightings of humpback and fin whales
SEMARNAT sets clear regulations for responsible marine wildlife watching in Mexico, including respectful distances and a ban on feeding wild animals. Huatulco's local guides are trained to follow and enforce these rules, guaranteeing an experience that respects the environment.
If marine life is your passion, we also recommend pairing the bay tour with the Turtle Release with Transportation, a unique evening experience that lets you take an active part in sea turtle conservation on Huatulco's shores.
Practical Tips to Make the Most of the Tour
Bringing the right gear and arriving prepared makes a big difference. Here are the best tips from travelers who have already done it:
- Arrive early at the pier: We recommend showing up at least 20–30 minutes ahead for check-in and boarding.
- Eco-friendly sunscreen: In Huatulco National Park only biodegradable sunscreens are allowed, to protect the coral reefs. Get it before you leave.
- Change of clothes and a towel: Snorkeling and the water guarantee you'll end up wet, and that's part of the magic.
- Snacks and water: Although the setting is spectacular, some tours don't include food. Bring fruit, nuts and extra water.
- Waterproof camera: A GoPro or a waterproof pouch for your phone is a must.
- Water shoes: The shores of some bays have rocks or gravel. Water shoes make it easier to get in and out of the sea.
- Seasickness: If you are prone to motion sickness, take preventive medication the night before or at least one hour before the tour.
- Book in advance: In high season (Easter week, summer, December), spots fill up quickly. Booking online guarantees your place.
Recommended Season
| Season | Months | Sea Conditions | Featured Wildlife | Crowd Level |
|---|---|---|---|---|
| Dry (ideal) | November – April | Calm sea, crystal-clear water | Dolphins, whales (Nov–Mar) | High in Dec–Jan and Easter week |
| Rainy (low) | May – October | Somewhat choppy sea (Jun–Sep) | Turtles (Aug–Oct) | Fewer visitors, more peaceful |
The 7 Bays Tour in the Context of Your Trip
The bay tour is a perfect experience for the second or third day of your Huatulco visit, once you have settled in and gotten your bearings. If you want to build a complete, varied itinerary, these are other activities that pair very well with it:
- Day 1: Arrival, exploring Crucecita and the Sunset City Tour with Viewpoints and Tasting to see the bay from land.
- Day 2: 7 Bays Tour by yacht or catamaran. A full day on the water.
- Day 3: Jungle adventure with the Magical Waterfalls with lunch included to cool off among the tropical vegetation.

You can also complement the bay tour with a kayak outing before sunrise. The Sunrise Kayak Tour is an intimate, silent way to see the bays from a different perspective, paddling through the morning mist and the golden reflections of the rising sun.
A Moment You Won't Forget: A Traveler's True Story
“We left the Santa Cruz pier at nine in the morning. I honestly didn't expect much; I thought it would be one of those generic tourist tours. But when the boat entered Cacaluta Bay and the guide told us it was restricted-access and that we were privileged to see it, something changed. The water was a blue I had never seen. I snorkeled for the first time in my life there and saw a turtle glide right beneath my feet. I went home convinced that Huatulco is one of the most beautiful places in the world.”

Food in the Bays: The Flavor of the Oaxacan Coast
Some stops on the route include free time at bays with restaurants and beach palapas where you can enjoy local cuisine. The food on the shores of Huatulco's bays reflects the richness of the Oaxacan Coast:
- Fresh seafood: Shrimp ceviche, garlic octopus, fish a la talla and green aguachile made with the day's ingredients.
- Tropical drinks: Fresh coconut water opened right in front of you, tamarind and hibiscus (jamaica) drinks, and seasonal fruit juices.
- Artisanal mezcal: There is no better way to celebrate the sunset in the bays than with an Oaxacan mezcal. At some palapas it is served with worm salt and orange slices, as tradition dictates.
- Coastal tlayudas: The seafaring version of the Oaxacan tlayuda, with beans, asiento (pork lard), quesillo and fresh seafood, is a delicacy not to be missed.
If you want a deeper experience of coffee and mountain products, the Coffee Tour in Pluma Hidalgo is the perfect excursion to combine with your bay visit on a different day.

What is the difference between the yacht tour and the catamaran tour?
