Paddle to this cache location. There's a bit of a lagoon formed by the ravine, so you can pull out without the current taking your watercraft.
Because I want people to have success with this one if they bothered to paddle to it, I'm going to describe just where the cache is located. If you don't want that much information, stop reading now.
The cache is located up to your left as you paddle into the lagoon. It's on the southeast side of the cement structure that's there. You can actually see it before you paddle into the lagoon. (Leaves could block your view if you're out too far.) It's near the base of some trees growing up adjacent to the cement structure. Unless you're tall, you will have to climb the bank to reach it, so be careful.
