This hike was unique and a lot of fun! From start to finish, this hike definitely met the strenuous title it had earned. Beginning at the siphon draw parking lot, I took the corresponding detour to get to the siphon trail, which was a steady incline that gradually got more steep as I ascended up toward the basin. Lots of loose rock, so good sturdy footwear is a must, and take your time to gain proper foot placement, as there is plenty of loose aggregate to slide and slip on throughout your hike. At about mile two you reach the basin and it was definitely interesting to ascend and see how water once shaped and formed the rock structure on all sides. Very cool! Just beyond the basin you go through a trail sprawling with large rock and thick foliage, but the path was clear enough to follow. Fellow hikers were pleasant and the trail wasn't too crowded at all. Once you reach the top of this strenuous trail there is about a ten foot rock climb/straight up incline, to maneuver, but is made easy enough by the natural foot holds and jagged rock to latch onto and pull yourself up. Once to the top you will see a clear path to the Flatiron, and it doesn't disappoint! Beautiful three-sixty views and the squirrels were hanging out, seeing who had come to visit them. I really enjoyed this hike and the weather was perfect! definitely suggest solid footwear and plenty of water. Enjoy this hike a lot and will recommend to family/ friends!
