Great selection of hikes! I did trail 44 (I think). I took the paved path to the top, where you get killer views of the Valley. In fact, there are killer views the entire way up. The walk up is fairly easy and not very long.
Once at the top, I wanted more of a workout, so I took the rugged way down. This path was super fun. A little more challenging than the paved path, and requires careful stepping. Once I got to the bottom I walked back up, and then back down the paved path. On the way back up the unpaved part, I got a teensy bit off trail, and had to shimmy my way down some loose rocks. It's pretty well marked, but I wasn't paying close attention. It took me a little over an hour to finish up 2x and down 2x. Really fun area!
