A bucket list item I didn’t know I had

Very well organized but in a friendly, helpful way. Was not as cold in the water as I expected. Just amazing

Best Experience Ever!

Our snorkel guide was Jenny, she was absolutely amazing and took care of every single need we had during this experience. She made sure our gear was on correctly and that our masks and snorkel were fitted properly! This was a big deal for me because nothing ever fits me right and she took the time to make me feel at ease with the whole process of dry suit and wetsuit! My daughter is a geologist/teacher and this has been on her bucket list for over 20 years! She and her husband and I had the best time and would highly recommend it! Thank you, thank you!

Once in a lifetime

Great experience not to be missed. Changing facilities leave a lot to be desired (back of a van). Other than that would I recommend, in a heartbeat.

Wow... incredible...

Wow... incredible experience. Once in a lifetime. You did not need any snorkeling experience or even know how to swim. You float very easily. They pick you up in a warm bus, drive you to the place, you get fitted for your dry suit and they help you put it on, then you waddle down to the water. Even with the dry suit, it was FREEZING so definitely wear WARM layers underneath and thick socks. My suit did not leak anywhere except around my head but not enough for it to be a problem. The water is incredibly clear and calm. No fish or anything but you can see forever. It is very cool. You have an area inside the bus to change out of your wet clothes if needed and bundle up and it is heated. They served hot chocolate afterwards and the pictures turned out SO cool. Loved the experience.

Do it!!!

Wow! What an incredible experience! The staff was friendly, professional, and helpful from pick up to drop off. We were given all the equipment needed and received excellent safety guidance prior to entering the water. Shout out to Quim, our snorkeling guide. One guy in our group of 6 was struggling/panicking a bit. Quim was so patient, reassuring and kind. He problem solved on the fly and gave us all an experience we’ll never forget. Quim also took some outstanding pictures that I’ve shared with anyone who will look!!
