Prior to redevelopment in 2000, this area existed at the site of what is now the Boulder Ridge Golf Club in San Jose and was popular for bouldering. It is listed here for historical purposes only.

The Mezzones was a very cool bouldering area in the South Bay.
It was pretty trashy, with graffiti on the boulders, but the sandstone was wonderful!
It is now a golf course and therefore closed.
