We went on a couple of tours - both involving "nature" - one was an excursion to a sea crocodile sanctuary. This was about 1.5 hours from the hotel.
Apparently the area was home to sea crocs, but they were captured and moved so people could move in. The crocs are in a lagoon and well fed, so there is no real reason for them to leave. I believe we were told there are a few hundred of them at any given time. We saw maybe a dozen, if that. There were lots of birds and a lizard or two.
We also stopped at a turtle sanctuary, so we have pix of turtles.
The second tour was really a "booze cruise" - we were on a boat tour of the bays, stopped to go snorkeling, I saw lots of fish, which I didn't take pix of - our camera is not for under water. But again lots of birds and a few sea turtles.
We also took pix of some interesting vegetation.
I'm afraid the pix aren't necessarily in order - but hope you enjoy looking at them anyway.
Can you see the iguana in the tree?
