Must do in Puerto! - Highly recommend! We saw 4 whales and hundreds of dolphins, so magical. The boat driver was very skilled. If you get seasick take tablets though, since it’s a bumpy ride. It was so beautiful on the water in the morning.

Great Experience! - We we went on two tours with Eco Adventures - releasing baby turtles and Dolphin watching tour - both of which we greatly enjoyed. Efrain and his brother were fantastic at communicating about both tours and showed up on time with smiles on their faces. Very well run and reliable tour agency that I would highly recommend! The Dolphin Watching Tour was particularly memorable - we saw hundreds of dolphins, a whale and some large sea turtles!

Brilliant tour operators - Eco Adventures are wonderful! Super-responsive on WhatsApp, with superb staff. We went on a dolphin and whale-watching tour with them, and our boat captain was hugely knowledgeable - we were often the only boat with a school of dolphins, which gave us plenty of opportunity to jump in and swim with them in an experience we’ll never forget. We took a tour down the coast with Juan Carlos, who was an excellent guide, and really responsive to what we needed. A really brilliant company working in a really responsible and kind way.

Dolphin-palooza - So many dolphins, as far as the eye can see. You can swim with them and theyll race the boat as well. But the true highlight was the humpback whales who our guide allowed us to follow for some time. We also saw many birds, fish, and sea turtles. Overall, a great morning enjoying nature and well worth the price.

Turtles, snakes and dolphins - It was fun, and I enjoyed it. Pickup was smooth and we saw lots of animals, the boat was nice. Recommend

Eco Adventures is good - We did two excursion with Eco Adventures and both were great. The bioluminescent lagoon (Laguna Manialtepec) one night and the dolphin watching the next morning. this outfit is well-organized. The rides picked us up on time. Handoffs between the driver and boat captains were smooth. Everyone was friendly and informative. Nothing felt rushed or harried. For the bioluminescent lagoon, forget about the open lagoon and head for the floating tents. It's much darker in there and you can see about twice as much glowing. Try to avoid brighter nights (clear, full moon)--the darker the better. For the dolphins, we saw probably a hundred. We also saw two sea turtles getting it on, which was hot. for me, the boat ride and the Puerto Escondido skyline from the ocean was cooler than the dolphin viewing itself, but I've done several dolphin things in the past. Highly recommend either or both of these excursions.

Awesome! - Great experience! Alex, our captain, was very knowledgeable and a skilled boat driver. We had a great time.

Would book again - Absolutely loved this tour. Unfortunately we were not able to find an English speaking guide and none of us knew more than very basic Spanish. We were able to still enjoy the trip and find dolphins, turtles and whales! What an incredible experience!

Amazing experience - Pick up and transfer with Mario went smoothly, very nice guy. Boat trip with Edgar was great too, saw hundreds of dolphins, sting fishes, turtles and lucky to spot a whale. It was incredible! They did their best to give us the best experience. Good info to prepare the trip in advance. The pickup time is informed a bit late, maybe because they have to wait to make the route until the last moment.

Perfekt tour but here overpriced - The tour was very nice. We saw about 30 dolphins and could swim with them. It was fun and really nice experience 😊😊😊 !!! BUT !!! Don't book it here per Viator. You can pay more less (like a half price) wenn you pay the tour directly to kapitan 😉
