This is one hike that should be on every Coloradan's bucket list. Yes, it's cliché. Yes, it can be crowded. Yes, you hiked it last year. So what? The 1.2-mile (one-way) trek just outside of Glenwood Springs is so surreally picturesque at the top that we could hike it every month and never get bored. Go early to watch the emerald waters shift to a bright turquoise hue before getting into prime photo position beside the waterfall at Spouting Rock, just a few steps away.
