5.00My boyfriend and I went on an excursion with a group of friends with Eco Explorer while visiting Puerto Vallarta. The experience began with a beautiful one-hour boat ride, and the views along the way were absolutely breathtaking. One of the most exciting parts of the adventure was swimming through a cave while wearing helmets. It was definitely a little scary at first, but it added so much excitement to the experience. The reward at the end was unforgettable—a stunning private circular beach that was one of the most beautiful and unique places we’ve ever seen. It truly felt like a hidden paradise. After exploring the beach, we spent about an hour snorkeling and enjoyed seeing the marine life and crystal-clear waters. The entire excursion was well organized, fun, and filled with adventure. A special thank you to Rodrigo, our instructor, Captain Hector, and Everett for making the day so memorable. They were professional, knowledgeable, friendly, and attentive throughout the entire trip. Their enthusiasm and commitment to safety helped us feel comfortable and confident every step of the way. If you’re looking for a unique and unforgettable adventure in Puerto Vallarta, I highly recommend this excursion. It was easily one of the highlights of our vacation!
Amazing Crew and Experience!

5.00My wife and I went scuba diving for the first time ever. Our diving instructor was Eric and he did a fantastic job explaining the equipment and the process. When we first started decending down the rope when were both having a feeling of panic. Eric helped us through it and we tried again. We ended up going on 2 incredible dives that lasted around 35 mins each. We saw a ton of fish, an eagle ray, a lobster, and a sea turtle! I would recommend this for any beginner.
Great Team! Highly recommend!

5.00I am so happy I chose to go with Vallarta Undersea for my scuba diving trip. The whole team was friendly and kind. From the very beginning Wendy was informative, helpful and great customer service. My dive master was Erik - so kind and patient! I was having hard time going under initially, he was so calm and understanding. He helped me calm down so I could get down and enjoy my dives. It was wonderful thanks to him! The whole team was a pleasure. Highly recommend this company :-)

5.00Excellent small group. Only us 4 men on the dive. Excellent staff knowledgeable about everything Staff knew that three of us had not had a dive for 5-8 years. For experienced people, let them know how much weight you really want. I knew I needed only 18 lbs but he had estimated 24 lbs with me. Otherwise everything else was perfect
