The 3rd site was water tunnel #9. Like the dams, it was built/dug to supply water for the sugar cane. This is a "fun" tunnel to enter as 75 feet or so into the tunnel it forks and right at the fork water drips down from the ceiling. Here Ibra is entering the tunnel. I'm already farther inside.
Trying to catch up to me Ibra took this picture of me.
