5.00We had a really nice snorkel tour. The boat was tidy and the equipment was well maintained. We saw the crew bleaching the equipment getting it ready for future users. The crew, Liber, Justice and Captain Rick were very safety minded and fun. The water was a little choppy, but it was clear and we saw some amazing fish. We definitely recommend this tour.

Not good for non-swimmers

2.00As we are not swimmers, we were not guided initially when booked. Since I took shallow waters, through we can adjust. Ideally we shouldn’t have taken shallow waters, so that at least we could hang on near the boat and see the reefs. Nobody guided that during booking or on multiple follow up calls.
Fabulous day out on the sea

4.00The Captain and the mate are great the snorkeling I been snorkeling deffernt places this is my top three so so close to the reef, cool fish but why not the 5 stars great question and I was going to rate this lower but the wife told me no 4. Here are the reasons 1. The welcome lady who you first see was rude and condescending. 2. It’s another 3+ mile ride to the boat. A nice couple ask for a ride, they did jot know and had an Uber ride they should say that. 3. I as many read included “Use of snorkel equipment” then detail of the equipment that all I want. Then you arrive you need the Tub as you read on a tub is not included as I stated been snorkeling many times this was a first since I have gear at home this will cost you $15.00 to $25.00 per person. This should be included in the same line item. 4. When we arrived at the boat meeting place 3+ miles away greeted by another lady with the same attitude as the First Lady I told my wife are they twins no just the same attitude. Do I think we got hustled Yes, not like me but I’m getting older so I miss things Thanks Captain John and Mate Carolyne
