Castle Rock is actually "Castle Rocks," to be more accurate. It is the series of post-volcanic rock masses that have formed adjacent to Mount Diablo State Park. From the marked trails, you can see the huge formations towering overhead, but for a better treat, head off trail and go explore the rocks and caves up close.

, New York native, I spent half of my life hibernating indoors, but for the past five years I have basked in the thrilling opportunity to enjoy year round hiking on the many trails of beautiful Northern California. In this blog I will continue in the tradition of trailhead, to recap the hikes I have taken and share the insights of my fellow hikers. Along with day hikes, I am also interested in dog friendly trails, and backpacking trips as well. Please feel free to offer suggestions of where I should hike next, or share tales of where you have explored. . Guest blog entries are extremely welcome as are your photos from your own hikes.
