The Castle Rock formations are a popular destination for local rock climbers in this scenic canyon along Pine Creek, with Mammoth Rock the largest. The prominent sandstone amid the oak woodlands is a beautiful contrast and a fantastic place to have lunch at one of the many picnic tables. The site is closed annually from February 1 to August 1 to protect nesting peregrine falcons that inhabit the area, so plan accordingly if you wish to explore more here.

Water, wind, and calcite erosion in per-volcanic sandstone formation. Slightly acidic rainwater seeps into the sandstone during winter rains and dissolves some of the calcite. Warm and dry days cause the moisture to pull the dissolved calcium back out of the rock, causing holes and caves to form. Watch for peregrine falcons and other birds of prey nesting high up in the Castle Rock caves. The upper trails are closed Feb-July to avoid disturbing the nesting birds.
