my kids, dogs, and I walk this Trail all of the time. They love to hunt for painted rocks here, and dinosaurs. ;-) there is a nice creek and waterfall. I would not recommend getting in the water. I believe they even have signs up about it. But there is a cool bridge and it is far more than a loop. It's more of a maze. Going any direction will pretty much lead you to the same place because all ends except for the front are blocked off. however, this is spanaway. So bring some sort of protection, just in case some weirdo is hiding back there. I've never had anything happen, but I've heard some stories.
