For this last bit, a floppy hat and mint tea in the water bottle is a requirement.
Some of the areas of the mangroves and shallow waters, kayaking is the only way to go.
For our guests, there is a kona kayak, made by hobiecat that can be rented. You can go their website and see directly.

It is a tandem- for two. However, we have had three people- one on the front catching a ride! IT is a very stable boat and so great for beginners. However, anyone renting our boat, must sign a release and have some boating/kayaking experience. Of course for obvious reasons.
Ours is the brilliant caribbean blue. We still need to come up with a good name!
