This is truly one of the most beautiful places in the world, this is a remote area and permit require to hike there (to obtain a permit please read this)
only 20 people allowed per day.
The hike itself is not an easy one but defiantly not hard and anyone in reasonable shape can do it, its a 6 miles hike roundtrip but it is hiking in the desert so you must carry a lot of water, wear light clothes and a hat and a lot of sun block.
It is an unmarked hike but you will get a photo guide once you win a permit from the visitor center (@Kanab, UT), we used a gps app on our iphone which tracked our way in and we hiked back out the same way.
the place is amazing and really worth all the efforts of trying to get a permit and hiking in the sun.
