A good experience - Matthew was great helping me feel at ease. It was an early tour and I was the only one. So pretty much got a private tour. Matthew took great pics. I didn’t realize they cost extra but I went ahead and got them. I recommend it.

Once In A Lifetime Experience - This excursion was top tier!!! I would highly recommend to anybody!!! Our tour guides were extremely knowledgeable, friendly, and helped us feel safe during the sea trek! It’s a once in a lifetime experience! They take pictures underwater and are available for purchase and we even had a chance to feed the fish. Run, don’t walk to purchase this excursion, you won’t regret it!!!

Non-swimmer - Great experience! As someone that cannot swim, I was able to complete the entire experience. It is nerve racking though, you must be comfortable in tight spaces and be able to stay calm. Deep or hyperventilating breaths will cause the water to rise in the helmet which if you are not expecting, could make you more nervous. Tour guides were great! I felt safe.

Zach & Luis - Our experience was absolutely PHENOMENAL!! We had literally the best 2 guides Zach & Luis. Upon entering the water my gf was very shy and timid because she can’t swim and just doesn’t like being in large bodies of water at all. Luis noticed that and made her feel so comfortable and reassured her that she had nothing worry about & he’d be there every step of the way. Once we were fully under water Luis checked on her multiple times. Zach captured the most amazing pictures and videos while making sure everyone remained safe and calm. These 2 men were so exceptional and great at what they do and you can tell they actually love it as well. We laughed, joked, and played around in and out of the water which also made the experience 10x better. My gf & I couldn’t be more grateful and thankful for such a beautiful & fun experience. I would recommend this experience to anyone BUT not without Zach & Luis!! 🇵🇷💙
