We really enjoyed our snorkeling tour. The guide was knowledgeable about different sea species and helped us find good locations and views of fish while snorkeling. It was safe, instructions were good, and a trip was entertaining. Highly recommend.

Thalia’s expertise as a marine biologist was amazing- she was helpful and taught us a lot and has that ecological and nature-based background. A true extra touch was the video she took and offered to send to us along with taking a photo of her laminated sheet of what we (likely) saw. Angel was the captain- he was very nice. Their rapport was amazing. The boat was the perfect size and the small group was fantastic. They also run their own company- Vallarta Natours- and that experience showed!!!

We were so thankful we booked a small group snorkeling tour with Thalia. We beat the crowds and got to soak up so much knowledge from our expert guide.

I really enjoyed this tour in Los Arcos. Comfortable boat ride with its captain Angel. Very knowledgeable tour guide Thalia, happy to answer any questions. We spent plenty of time snorkeling and got to see a lot of beautiful fish. If I ever do another tour in Puerto Vallarta, Vallarta Natours would be my first choice.

This trip was great! On our way we saw some dolphin, and turtles as well as some sting rays. Our biologist explained everything that we might see and how to swim with the currents to prevent us from touching the rocks. She was able to answer all my fish questions and made the trip so enjoyable. I will 100% be booking here again.

This was one of the best snorkeling tours my family has been on. It was great having Thalia (marine biologist) on to answer all questions about Los Arcos and marine life. The snorkeling was not rushed at all. She was absolutely wonderful with our daughter which made for a great trip.
