It's a tough hike. I carried my son and the water and I was beat. Took an hour down in the afternoon and 1.5 hours back up in the evening. Coming up after the sun is behind the mntn (about 6pm) is recommended. We got back to the 4runner at dark and it was much cooler walking then. You hike the trail cut into the mntn down to the bottom, then it splits at a little dirt open area with some trees and a trash can. Turn back to the left, up into the canyon, not straight. It's just a few minutes from there. I'm going to poke around on the Yahoo map, I'll post a link in a min. There is a shorter way that's steeper, but I'm not sure where.
Bring trashbags, people leave tons of trash, I forgot to bring some, and we couldn't carry any more than we had any way, which is why stuff gets left I guess.
