going to Calaguas Island

Passing by these coconut trees(?) was part of our trip going to Calaguas Island, as well as passing by a bunch of mangroves.. and we passed by this guy who was about to enter this forest in the water.  I don't know what he will do there though.. maybe to collect some woods? or kill some crocodiles?  I don't know.  But he quickly vanished, like in a matter of seconds.  He was eaten by the darkness.

I wonder what it would be like, entering that kind of forest.
