A little bit of cold for a once-in-a-lifetime snorkel/dive

Friendly and patient DIVE.IS crew/staff/guide/drivers. They know everything like the back of their hand, and they come ready to equip you with everything you need to get in the water. Hot chocolate and cookies to round it off at the end. Tip: Make sure to use the restroom BEFORE you put on your dry suit, since putting on and taking off the gear is like prepping for a moon walk (bulky and tight!) and requires help. Also your guide will take some photos throughout, and you’ll have the option to purchase them.

Gotta do this

This is a very unique experience. Initially a little chaotic with multipke people at various stages of check in. Go with the flow snd when you connect with your guide use him/her in dessing. Personally, I think some snorkeling experience is best.

Great experience

Unreal experience. I wouldn't advise anyone with new or sensitive ear piercings to go as the hood is very tight and can irritate you ears. Staff are so friendly and helpful

A bucket list experience but not for the faint of heart

Our guide Isabella was so fun and we could tell that she really knew what she was doing. The atmosphere was fun and lively, but since it does require some safety precautions it is not something I'd recommend for people with claustrophobia or those fearful of the ocean. We felt completely safe with our guide and it was exhilarating to have this once-in-a-lifetime experience!
