About this crag

It sits uphill from Indian Rock rather than sharing that park's hours. The specialist guide identifies some highball problems and a stepped descent. Preserve the Indigenous mortars and other cultural features instead of treating every surface as a climbing hold.

Recommended equipment

Bring equipment appropriate to the climbing style and local conditions. A helmet is strongly recommended.
