We recent took guests to Kayak here, and had a great time! Beautiful passageways through mangroves, an island to paddle out to, lots to see, and a good workout!
Two pieces of advice -- take a good look at the map before starting, and try to keep it in some type of dry bag, as it basically dissolves as you get wet while paddling. Also, ask about the wind and sea conditions out in the bay before starting. The ocean kayaks seemed up to the job for the waves we saw, but it can be a real challenge paddling against the waves, and you can expect to get VERY wet with water coming into the boat. There is a protected cove you can explore, as well as the mangrove trail, if it is too windy to get out to the island.
