  description: Ghost Trees is Pebble Beach's secret big wave—a right-hand slab named for the white, ghostly Monterey Cypress trees that frame the break. The Carmel Canyon focuses swells to produce waves in the 40-60 foot range on rare winter days. The spot is controversial: jet-ski bans limit access, and the exclusive Pebble Beach community has mixed feelings about the surfers. When conditions align, Ghost Trees produces some of California's most photogenic big wave barrels.
