Deep-water soloing, also known as psicobloc, is a form of solo rock climbing, practiced on sea cliffs at high tide (originally, but also on reservoirs, rivers, swimming pools -indoor, that relies solely upon the presence of water at the base of a climb to protect against injury from fallings from the generally high difficulty routes.

Although this is viewed as a relatively new style of climbing, it probably originated in the late 1960s or early 1970s in Dorset, Southern England or Majorca. Real development of the style began in the mid-late 1990s, and is progressing to this day.

Deep water soloing is practiced nowadays in Lebanon especially on the rocky shore of Chekka and Ras el Chakaa where you can find caves and cliffs.
