We were on a family cruise with 3 divers. I booked online and everything was smooth. Nahum was a fabulous Divemaster, the boat was comfortable and not overly full (Awesome!). Definitely would dive with this shop again.

Our dive master, Nahum, was excellent, as was our boat captain Martin and other tour guide Rodrigo. We have booked different excursions with this group and are always pleased. We left at 9:00 am and returned around 2:00 pm. There were 4 divers and 8 snorkeler's on the boat. They provided all of the equipment and it was in good condition. We only brought our masks, however, they will provide that if you need it. Abundant sea life. We were down for 45 mins each time and went down 40-50 feet. December weather was good water was fine. We were provided a spring suit or shorty.

We had an amazing diving trip to Marietas island. The whole team of Vallarta UnderSea is very efficient, kind and friendly. Our dive master Erick was great. He helped us with everything, gearing up, pointing us to amazing fish and took us to an ubelivable cave diving, taking care of our security and needs. Thank you very much to all the team. We will be back soon.

Thanks to Vallarta Under Sea for a great diving experience! My husband and I dove at Los Arcos with one other diver and our fantastic divemaster, Erick. There was a group of snorkelers and a group working on their diving certification on our boat as well. Erick and the entire crew were very professional, and we felt safe and well cared for. Erick obviously knew the area very well and so was able to find a large variety of sea life to show us, including octopus, eels, lobsters, a sea turtle and a large spotted ray, along with the abundant tropical fish in the area. I highly recommend this dive shop and would dive with them again if I ever returned to Puerto Vallarta.

Bere, Alex, and Javier - our guides for our trip were great! Alex was the scuba dive guide. Bere was the snorkel dive, and Javier was the boat captain. My son and I scuba dived and was guided by Alex. He was very thorough with his pre-dive instructions. The pace of his guiding underwater was perfect. Not too fast, and not too slow. We did two tank dives on this trip, both were 45 minute dives, with an average depth of about 60 to 80 FSW. Bere was the snorkel guide. My wife was one of the snorkelers, and she had all praises for Bere. She said, as small as Bere is, she was very strong pulling other snorkelers through places where they needed to pass. She was very energetic, very charismatic and very informative. Alex, the boat captain was awesome navigating the boat. There were 12 of us in our boat. It was a 30 foot boat. Alex made the extra effort to stop at times so we could see the bottle nose dolphins, and diffferent parts of the Mariettas islands. I would highly recommend this scuba dive and snorkel trip with Vallarta Undersea adventutres.

This was a good experience. I had called a few places (chicos they were a bit unprofessional) and these guys took care of us. Our instructor was amazing. I was the only certified person, and my niece and nephews were in good hands… I greatly recommend using them.

This was my first time going scuba diving and it was truly an amazing experience, I usually don’t leave reviews but I had to come and leave this one. The guide on this tour were very knowledgeable and experienced I felt totally safe the entire time could not recommend enough. Our guides were Nahum/ Erik and Hector.
