The hiking and snorkeling adventure was so much fun! Francisco was our tour guide and he was so kind and made the experience great! Learned about a ton of birds from him which was awesome!

We had a wonderful day with Ecotours Vallarta visiting Colliminas to go snorkling and then to Yalapa to explore the area and have lunch. Yalapa is a private tour so you pay for the guide and the boat captain and the boat can take around 10 people. There was just the two of us in this trip. Mike was our guide and Raphael was the boat captain. We had been with Mike in an earlier trip and he is a fantastic birder and a super nice person. He also know a lot about whales and marine life. We started out from the marina and within 15 minutes we came upon about 6 humpback whales and watched them for awhile. Raphael was careful to keep a respectable distance. They come here in the winter to have there babies and then migrate back to the west coast of United States in the warmer weather. We then snorkeled at Colliminas for half hour. The water was in the 70s and calm and we saw many types of fish. Then on to Yalapa which is nestled in a beautiful bay and very picturesque. We walked up to a beautiful waterfall that did not have a huge amount of water as it was the dry season The town has lots of restaurants along the beach and lots of things to buy in the way up to the waterfall. We then had lunch at The Marlin. My girlfriend had fish tacos and I had shrimp tacos and we shared guacamole. The food was good but not fantastic. Mike pointed out several sea going birds(turns, pelicans ) and we also spotted grackles and a beautiful Trogon. My girlfriend was delighted to hold an iguana for a photo(100 pesos). We took some nice pictures at the waterfall. We left at 9 am and returned about 3:30. It was a wonderful day to do something different as we have been in Puerto Vallarta for a month, Ecotours does a great job and Mike and captain Rapheal could not have been better. Highly recommended.

Amazing day out. The guide Fransisco and captain Martin were very knowledgeable. We saw so many fish snorkelling and Fransisco was great at identifying the birds. Martin even found us the rays jumping out of the water. Highly recommend the private boat tour with a small group. On the way back we went close to downtown and Fransisco knew the history of the area

I booked a private snorkel tour with EcoTours Vallarta for myself and my two young kids (ages 7 and 8), and I honestly can’t say enough good things about the experience. From the very first phone call, the team was accommodating, flexible, and incredibly kind. I explained our situation—first-time snorkelers, not the strongest swimmers, and two easily overwhelmed kids—and they immediately made it clear they could create something safe, manageable, and special for us. They absolutely delivered. Our guide, Margarita, was extraordinary. Calm, patient, encouraging, and endlessly kind with my kids (who were… not easy!). They had never snorkeled before, and she handled every little panic, fogged mask, gear adjustment, and mid-ocean meltdown with complete grace and professionalism. She had this amazing ability to make them feel safe and capable without any pressure. She also happens to be a skilled diver, a knowledgeable marine biologist, and just an overall exceptional human being. We also had an excellent captain, Martín, who navigated smoothly and helped with gear and logistics behind the scenes, making the whole experience feel seamless and safe. The tour itself was gorgeous—we snorkeled at Los Arcos and saw a wide variety of fish, including pufferfish, a moray eel, and a beautiful spotted ray. The timing was perfect, the spots were uncrowded, and the boat was clean, shaded, and very comfortable. This trip completely exceeded my expectations. It was easily the highlight of our week in Puerto Vallarta, and I’ll be recommending EcoTours (and especially Margarita and Martín!) to anyone traveling with kids—or anyone who wants a thoughtful, well-run, truly memorable marine experience.

Excellent, you just have to take into account that they are in the open sea, the guides say it is a calm environment and you can actually find all kinds of marine animals, for clasutrophobics

Joined a small group (4 of us) to go snorkelling at 2 locations. Our guide Cynthya was amazing, as well as our Captain (I unfortunately forget his name). We had a lot of fun. Conditions were excellent for seeing fish, and the emphasis of the tour was to go to the spot with the best conditions and least crowds. We were lucky enough to see whales and dolphins on the way. Cynthya spotted a ray and s turtle gor us to see while snorkelling.

We had an amazing trip! Michael, the guide, was fabulous and very knowledgeable. The boat captain and the office staff were great too. Highly recommend this tour. It is well worth the money. It’s also a great way to see the PV coast from Nueva to “where the highway ends” and beyond where the villages are only accessible by boat. We saw many kinds of fish, a sea turtle, spotted rays, and urchins and coral. And all this without the hassles of a large tour group on a cramped boat. The personalization of the tour is a great selling point.

This was scheduled independent of but as part of a cruise that stopped for a day in PV. It was WAY better than a shore excursion through the ship. It was easy to schedule, great communication, very fair pricing, excellent staff. Our guide Michael was amazing. The captain of the boat was really wonderful as well. If you arrive by cruise ship their offices are within walking distance. I would definitely recommend this tour company.

We had a great private tour with Cristina and Rafa to swim through Los Arcos and then on to snorkel in a magical private cove. They made sure we found clear water and pointed out dolphin, lobster, eel, turtle and more! Highly recommend this smaller company rather than one of the big tours. Very professional, friendly and knowledgeable!

This was such an awesome hike. Maggie was a fantastic guide and knew so much about the area. The path you walk along isn't terribly steep but you will want to be in decent shape. The snorkeling is beautiful and we even saw a turtle and heard whales!!!
