SPA133 - Coming from Martinez, take I-80 W to exit 22 for Pinole Valley Road. Turn left at Pinole Valley Road and then right at Castro Ranch Road. Follow Castro Ranch Road to the intersection with Conestoga Way and turn around there. Park on the north side of the road by the first guardrail and pull-out. Meet at the pull-out. There is a telephone poll there (and should be yellow flagging if it hasn't been removed) marking the path back to the waterfall. *This site has lots of poison oak - Please bring a change of clothes and Technu - If you are very sensitive, you might want to consider not surveying this site*
