Majestic Castle Crags have inspired enduring myths and legends. More than 170 million years old, these 6000-feet tall granite spires in the Castle Crags Wilderness border the northwestern edge of Castle Crags State Park.
Few of California’s State parks display impressive monoliths adorned like a castle with towering spires and few permit rock climbing. Castle Crags State Park is an exception. The scenic beauty is best enjoyed from a distant vantage point where one can see the range of surrounding landforms. The monolith and its surroundings are a microcosm of the Klamath Mountains where many such monoliths intrude and stitch together a crazy quilt of much older rocks. The surrounding rocks include the Trinity ultramafic sheet, the largest exposed body of ultramafic rock in North America. The ultramafic rock is often interpreted to represent an ancient ophiolite – a slice of the oceanic crust.
