Florida Keys
From our sun deck, you will have a panoramic offshore view of the Florida Keys and can view the ever-changing colors of the Atlantic Ocean. Once we reach the reef, you will be able to observe the coral reef through our large viewing windows, which are large enough for everyone to observe the reef at the same time and are located along the center of the boat and installed flat so there is no distortion other than what nature creates. Everything you see on our tour is or was alive and the reef itself is built off of many varieties of living coral and teems with an assortment of sea life. Your tour guide will be able to point out all kinds of sea creatures which may include sea fans, sea plumes and hundreds of fish ranging from small tropical to larger species sought after by local fishermen.

Older boat. Dirty windows - couldn’t even see outside clearly. There was a musty smell too, likely because of inside carpeting.

Nice, knowledgeable crew. Clean boat. Good amount of time out there. We had a cold windy day but being inside was nice and it was fun to see all the fish through the glass!

Even though the ocean seemed calm, the boat was rough getting to the reef. Once we were at the reef I was expecting a stilled boat, but instead they kept moving. The flat boat bottom kept rocking rough.

The staff is super friendly and we enjoyed the ride. It is 45 min ride to the reef and 30 min at the reef and 45 back. We saw a shark, sting ray, lots of fish and a turtle.
