Last week I visited hidden Mystic falls which is close to Telluride, Colorado. It is an amazing box canyon waterfall that you have to scramble a bit for to reach. There are many pages on the web that detail how to reach it. The best is probably found here. I rode to the trailhead in my little Subaru without any issue but I might be a lot less careful than most so hiking the last part is not a big deal if you need to especially since the descent to the falls is really quite short. I have three favorite images to share that were taken at different angles and focal lengths.
My favorite is the tighter composition at the end but it does omit some of the context. I am guessing this place is going to be awesome in fall! Lastly as a bonus, here is a 360 degrees panorama of the place. Follow the "view on google maps link to see it in full screen glory and don't forget to look all around!
