Portlock Cliffs
This area is also called "Chinawalls" or Kawaihoa. To jump off the cliffs, you hit 25' deep churning water that has cost many people their lives.
Beautiful, breathtking and treacherous, the cliffs on the southwest point of O'ahu, are made of tuff (volcanic ash). With years of erosion, the look of these cliffs is soft, wavy and smooth.
