Grenada and the Tropics

I arrived in Grenada last Tuesday and its vastly different than any environment I have ever been in. We haven't reached any uninhabited islands yet, as Grenada is relatively developed. Most of the beaches here are privately owned and any of my bushcraft skills I would like to practice here I fear would attract too much attention. Tomorrow we make passage for Curriacou, an island that has a lengthy history with ancient peoples who migrated there from Northern South America. One account I read described "pottery literally falling into the ocean" from the ancient inhabitants.
My plans are to make a series of tropical survival videos with the help of my brother, so if anyone has any advice or suggestions in this area please share, as there appears to be a relatively steep learning curve in the tropics, in my opinion.
