This hike is best done early winter and winter. During the spring and fall, it is PACKED! and since the trail to the flatiron is very narrow and steep, hikers have to be wary of those below so as not to accidentally cause rocks to tumble on them.
we did this hike about 3 weeks ago, all the way to the summit. the siphon draw portion is typical desert hiking, until you reach the slick rock. this is where it gets really interesting. i've heard there's a waterfall there, but it was dry when we went. from here, you can explore some of the lower mesa's, but if you continue on, keep a sharp eye out for the spray painted dots telling you where to go (but you won't really get lost, just a little off trail). it's part scrambling, part hiking, but very cool. trees and narrow slots to scramble over. and then,there's the top! awesome views of the valley. if you go other than summer, bring something warm as it is very windy up there.
we even saw a gila monster our first trip there (a year ago), so you never know what's gonna show up. take a snack and enjoy the summit. it's a great hike. read more
