Highly recommend, Jana was amazing!

This was absolutely incredible. I was a little worried about the cold but the dry suit worked great and the staff was very knowledgeable about the process and was able to answer all our questions. Our guide Jana was amazing! She has a passion for the outdoors and really helped make the experience. I highly recommend this tour- I can’t put into words how incredible the views are!

No Puffins/But a humpback/ would recommend if had both

Hi First off, no fault of your own. I have booked many times through your company and everything was fantastic. However, today we were promised a puffin tour to puffin island and it was cancelled do to weather. We did still do the whale watch part, some I’m requesting a half refund. Please let me know if that is something you would consider. Thank you.

Fantastic Experience with guide Emilio!

This was such a cool experience made absolutely fabulous by our guide Emilio. Went with my 12 and 15 y/o who have minimal snorkeling experience and they did great. We wore long johns as a base layer and the outfitter provides a thick warm jumpsuit layer that fits under the dry suit. Your lips are really the only thing that get cold but it goes away. Emilio made sure that everyone felt comfortable and at ease, paid attention to little details. It seems like all of the guides are exceptional. We made the mistake of not bringing cash to tip and there were no electronic ways to do so, like venmo, etc. Bring cash! If all guides are as fantastic as Emilio you will want to tip!!

Unable to do as I did not...

Unable to do as I did not have ability to get medical clearance as we booked too close to date . Non negotiating at 60 years old with no health issues this is a ridiculous policy for snorkeling , ageism.

Once in a lifetime experience.

Fantastic time - Alex T was a kind, patient and attentive guide, he made the entire experience calming and more enjoyable. Truly a unique experience for those whom hold a passion for nature and adventure. The scenery was absolutely stunning especially the underwater troll hair.
