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!

Our guide Juan Carlos gave us the best day on the coast! We did the Oaxacan coast tour and got to visit an island with crocodiles and feed deer, go snorkeling and see colorful reef fish, and visit various sites along the coast. We also had a cacao and mezcal tasting and he took us to a great beachside restaurant for lunch. Bring bug repellent (there are vendors you can buy it from for around 100 pesos) for the island visit. Also bring some cash for breakfast. We had a nice breakfast on the island near the crocodiles. That was around 400 pesos for two people. Plus they ask you to tip the boat captain who brings you to the island. On the boat there is no shade so also bring a hat. The lunch spot was great for super fresh seafood and took credit cards. I would definitely recommend this tour and Juan Carlos. It was a highlight of our trip.

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!

It was amazing, efrain was an amazing guide and brought us to this small location, where the 3 of us (my girlfriend me and Efrain) took off in our kayaks. The view was nothing like I ever seen before. Beautiful birds everywhere. An other comment said it reminded them of jurassic Park and I can only agree. What an amazing experience, I would recommend it to everyone.

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.

We had the most amazing experiences in Puerto Escondido, some of them the highlight of our trip thanks to Eco Adventures. During our stay, we did 3 tours with them: Chacahua National Park, Dolphin Tour and Sunset Horse Ride. Pick up was always on time and they communicated well on whatsapp, reminding what to bring to before the tour. Super thankful they managed to squeeze us in for the sunset ride last minute too! Juan Carlos Gama was our guide for two of the three tours, he spoke in fluent English providing good explanations of the wildlife in the park and was super sweet in checking in on us regularly and took some amazing photos & videos for us! For the Chacahua National Park, it was an amazing and surreal experience being amongst the mangroves watching beautiful birds around. After the boat ride, you get a few hours on the beach for lunch & swim. We went near NYE so it was crowded with locals but we had some delicious freshly caught fish for lunch! It ended up being a private tour with just the two of us and we were amazed to see the bioluminescent planktons at night under the starry night. You can swim there at night but we didn’t end up going in. It is a long day given it’s a 1.5 hour drive away but worth it in my opinion! The Dolphin tour with Captain Ezy was one of our trip highlights. We saw hundreds of dolphins, a string ray, a water snake and even caught sight of a humpback whale! Bring sunscreen and a dry bag! It can get quite choppy out there and when we catch sight of wildlife, we accelerate towards to it to get a closer view so you can imagine it can be a bit bumpy but it’s all good fun! The sunset horse ride was very scenic, the route winding through farms, crossing rivers and ending on the beach for sunset. The horses do seem well trained but there were a few instances of a few misbehaving (sitting down or starting to gallop). The guides were good at rushing to help however not all speak English. We have been horse riding before so we knew how to control the horse for the most part, if you are afraid or tentative about horses then perhaps this is not the best for you to start with. You get the chance to try galloping on the beach which was an amazing experience! The ride back after sunset was quite dark but horses have great night vision and know where they are going. You can bring a head torchlight but make sure you bring insect repellant and spray ALL over - the mosquitos come out after sunset and they are vicious! We had the best memorable experiences in Puerto Escondido thanks to Eco Adventures and Juan Carlos. The whole booking process, logistics and tours were the easiest and most stress-free of all the tours we did in Mexico.

This was an incredible experience with an excellent tour guide. We were picked up and dropped of from outside of our hostel and received ice cold beer and water on the drive there and back. Would highly recommend this tour. Excellent value.

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.

How do people not see that this is a a business and not conservation? If they truly cared about the preservation of these turtles they would not allow Instagram happy strangers to participate. Instead, professional handlers would release them whilst those truly interested in the process could donate. Additionally, the time of day they release them is not conducive to a release program. Sunset is for happy snaps and not for their chance of survival. The vast majority dont make it to the water. It's as if, once you pay, you own the turtle. Disgusting in every way. If you care about tutle, donate to a real conservation group and stay away from this proftering ritual!

Excellent service from the driver/guide. The introduction and explanation at the site was a bit sterile and short, they should invest more on the teaching part. Overall, a good experience but the cultural/knowledge part of it is lacking.

We had a great experience! The hotel pick up and drop off made the experience accessible. Our driver Mario was friendly and provided bottled water for us. The beach where we released the turtles was quiet and we released them during sunset. The conservation volunteers spoke both English and Spanish and were knowledgeable about the different species and ensured the turtle safety throughout the release.

Highlight of the trip for our children. Amazing tour and location. Mario was very profesional and went out of his way to provide us the best tour ever. Can highly recommend this tour. Gracias

This was a magical experience and a highlight of our time in Mexico! We did the 6am trip and saw loads of local birds and fauna in calm and beautiful surroundings. It was really interesting to learn about the mangroves and our guide, Mario, was helpful, informative and friendly. There was an opportunity to get a snack and some coffee before we got into the kayaks.

This was the highlight of our whole trip to Oaxaca. Mario picked us up from our hostel and drove us through beautiful farmland, telling us about some of the challenges regarding tourism-driven development, environmental protection, and water management along the way. We arrived at a riverbank, where we were ferried across to a magical sandy peninsula between the ocean and the river. After a short walk, we boarded kayaks and paddled up the river (no current) to the lagoon. The kayaking required virtually no skill or prior experience (just be prepared to get a little wet from paddle drip). It was like being in Jurassic Park. We’ve done a lot of kayaking in coastal areas, but this was beyond anything we had experienced. The beauty of the mountains in the distance, the lush forest, the winding channels through the mangroves, and above all the absurd profusion of birds, left us awestruck (even the sometimes surly teenager). We saw many bird species we had never seen before. And even familiar ones we saw more up-close than ever before. Mario was an expert on local wildlife, and guided us gently through the lagoon, never rushing us. After returning, we watched the sunset from a palapa on the seashore while drinking from coconuts. This is a very special experience, and I hope that this place remains wild and free forever. Mario was prepared with everything and his personal stories really added to the experience.

Juan Carlos was an amazing guide. He’s very polite, knowledgeable and took us to some amazingly secluded places mostly known to locals only. The lagoon was fantastic! Seeing crocodiles just a few feet from you is magical. It’s great to see how people come together to protect nature and create unique experiences for visitors! We had an amazing day!
