Just 8 guests! Marine Biologist guides, go further, see more dolphins & turtles then snorkel the best uncrowded reefs...
We start by taking you further offshore and exploring a greater area than others, ensuring you have the best chances to see the most dolphins, sea turtles, mantas and even whales!
Ever wanted to float next to a sea turtle or a dolphin?
We offer respectful, passive in water snorkeling with dolphins, sea turtles and manta rays in the open ocean!
These encounters depend on the animals, we do not chase or interfere with them.
Then we cruise back to the coast to visit the bays and snorkel one of the best hidden coral reefs in the Huatulco National Park away from the crowds.
Our boat Stenella was built in 2022 for ocean adventures with a deep V hull, marine toilet, cushioned seating, canvas roof and swim ladder.
There is an underwater microphone to listen to the dolphins and whales!
Our tours support dolphin and whale research.

Smaller, powerful boat with 8 passengers and one skipper. The actual guide, Peter, had to dismiss himself as he wasn’t well. Tito, the skipper, was informative and was knowledgeable about local fauna. It took at least an hour to get to the snorkeling destination and unfortunately we didn’t see a single critter on the boat ride to our reef. That journey felt long. Once there, Tito pointed where to snorkel for best viewing and it was full of diversity and very safe. We snorkeled for a good 30 minutes and it never felt like there was a rush to get back to the boat. Access into the boat was via a ladder so likely not for everyone. On the return, we toured along the bays of the Nat’l Park. Tito informed us of some very cool facts about turtles, dolphins, local whales and transient whales. I will be a hit at my next cocktail party. We went in search of marine life as we headed back to our drop off point and came across a couple Spotted dolphins that teased us, some olive ridley sea turtles (see, I was listening) and some manta rays that would ‘fly’ out of the water. That was fun. Total time out on the boat was 4.5 hours which was more than enough. No humpbacks to be seen and it may have been due to the swells. That would have given the trip higher marks but I know you can’t guarantee that sort of thing. We weren’t sure that this trip had the value but Tito was a pro, the people were nice and the water was fresh. I’d recommend bringing snacks, food as granola bars and apples were all that was offered. Small bathroom amidship but nobody used it. I’ll say thankfully.

The guides were very knowledgeable. It was a wonderful experience. Snorkeling and seeing humpback whales were a highlight! Knowing the tours help fund marine research adds to the value of the tour for me.

This small group (7 people plus 3 crew) ocean eco excursion was outstanding. We saw humpbacks, including the first baby whale sighting of the season, many turtles, and a pod of spotted dolphins. Snorkelled a beautiful reef in a secluded bay in the national park. Lots of fish of all kinds. Followed a humpback and got pictures of the underside of the tail which uniquely identifies the whale. Guides Peter (marine biologist) and Tony were very knowledgeable, informative and personable. Peter posted high quality still pictures, drone and under water videos of the whales and dolphins that we saw at no extra cost. There was no upselling. Trip lasted 4.5 hours and exceeded all expectations. Best excursion we've ever been on. Well worth the price of admission. Hotel pick up is not included. You have to make your own way to the marina and back.
