Such a great and unique...

Such a great and unique experience, highly recommend. The tour guide was great at keeping us informed and accommodating our last minute sign up. As an American on the plus size, I was nervous about the wet suit sizing. I had not read many reviews talking about fits or seeing photos of people similar to my sizing in the various tours I looked at. Luckily, we were able to fit into the suit and I noticed they even had a few that were bigger. (Womens XL fit at home) I’ve never been in a wet suit before. It was a positive experience at keeping you from getting too cold. The team talked us through and helped us put on our gear, it was much needed! Recommendations- make sure to have good quality base layer on. Bring a hairbrush, chapstick, and face moisturizer as they are subject to the water. Book a hot springs that night. Hardest part of the whole event was walking back in the wet suit, it’s manageable though. And your neck will be sore after lugging around your head gear especially if you’ve never experienced a wet suit before, I wish I had brought icy hot. Not sure if this is the same for everyone. Either way — Definitely would recommend!

Great and Unique Experience!!

Exceptional experience for everyone! The tour provider personnel were excellent, handled each guest with kindness, efficiency, humor, and expertise. The equipment was clean and modern, kept us very warm on the snorkel in the fissure, and we were expertly assisted to put it on. Our group guide, Arman, was SO great with a couple of our group that had severe anxiety about the experience and created a safe and supportive environment to enjoy every bit of it!! Thanks to DIVE.IS for a great day and highly recommend this tour!!

MUST DO!!!!

Absolutely astounding experience with Dive.is. The only fault was of my own doing. I have leaned to not just rely on Trip Advisor for the full experience. Please check out their website directly to see their full offerings! I will do this with every experience from here on in, so I don’t miss the above and beyond options.
