I did this trail on a clear beautiful Sunday. The panoramas were spectacular. A nice mix of trails across open prairie, slickrock, a well placed and sturdy ladder,sandy canyon riverbed and shady forest in the back canyons. Some scrambling involved but not difficult. The trail was very easy to follow. Highly recommended to experience the beauty of Canyonlands NP Needles district.
I loved this trail. Some challenge for a 63 year old, but worth it all. Be sure to take bug spray because the mosquitoes were pretty bad along the low places where there was still a lot of water. Much easier than the Squaw Canyon/Big Spring Canyon Loop.
