Great reef, beautiful fish - Very fun afternoon. The reef was amazing, lots of fish! Quite choppy and cold but well worth it. Candace was so encouraging and patient with all the inexperienced snorkelers- if that’s you this is the trip to book

Amazing Experience - First time snorkeling and my son and I had a blast. Great place if you’re looking for a beautiful location for snorkeling. Captain Pip’s provides an awesome experience, genuine hospitality, even free snacks and drinks! Highly recommend!

Great sea life - This destination is one of the better snorkeling areas for variety and quantity of sea life. It's not far from shore so the trip there and back is just right.

Go directly to snorkle company not Viatot - Lack of communication from Viator or from Snorkle company. Text from one company reservation was with another. Almost missed it. Trip was great. Price through Viator was double what I would have paid going directly to company. I had good experiences throughout Greece Malta and Italy. Disappointmened this time.

I was over charged for... - I was over charged for the trip by booking through Viator. The price was double compared to booking straight through the snorkeling vendor.

Scammed and out of money - Would have given it zero stars if I could. We were scammed. Given a pin on Google maps, no address, no one there when we arrived. No answer on the phone number. It was behind the City building. They were very sweet and said they've never heard of any tours there. So sad. Last day of vacation. Too late to get another tour. Reputable companies were sold out and very sweet. They said that they have never heard of this buisness. Zero contact information. Says based out of NY. Do NOT get tricked. After looking further, says 3 hour snorkeling cruise as title THEN, no snorkeling, 2 hour cruise- comes with snorkeling equipment! Haha. Out $178 for me and my 8 year old daughter. Trying to get a refund. Viator was easy to get on the phone and tried to call the company as well, no luck. Scammed, sad, and out a lot of money:(
