We love this time of year when the leaves change color, drop off and our old hikes becomes something new. Extra points if you knew that carotenoids cause yellows and orange, and anthocyanins cause red, pink, or purple. Try some holiday hiking to see how the experience changes on your favorite trails. The views open up, there's more water in the streams and springs and the chill in the air motivates you to go a little further. Find the trail that's right for you on the Park Finder.
