I hiked up Mt Diablo on Saturday! Ok, it was the North Peak, which is the second highest of the four peaks at Mt Diablo (I got to another one of the four peaks as well). The website everytrail.com has this to say about the trail that we took to get to the peak:

My favorite path to North Peak is definitely the hard way: five miles and over 3,000 feet of climb on some of the steepest trails in the Bay Area. The struggle has rewards beyond knowing you've walked from near sea level to one of the highest accessible points in the region. In springtime, the hillsides light up with wildflowers; in winter, rains cleanse the skies so you can see the snow-capped Sierra peaks hundreds of miles away; in autumn, tarantulas prowl the trails in search of mates. Summer's about the only time when it's too hot to attempt this hike.

This hike also has a bonus: a jaunt along the Mount Olympia Trail, notorious as one of the steepest in the Bay Area.

Pics will be on Facebook :D
