Not sketchy, well kept trails along the river, a few waterfalls, educational stuff about salmon breeding. If you go in the spring you can see the tiny salmon hatchlings before they leave the human made breeding grounds, in the fall you can see the adult salmon finishing their journey upriver (and up waterfalls) to reach the place of their birth. It's an awesome sight to behold (though a little sad because they are close to the end of their life at this stage)
