Gihon Spring feeds the Pool of Siloam, where Jesus cured a blind man with a mud mixture and then told him to wash his eyes. This place has a number of complex water supply systems constructed during the Canaanite and Israelite periods and is the site of Solomon's annointment (1 Kings 1:33-34, 39). The Canaanite tunnel is dry and the Hezekiah tunnel is wet, so be prepared to walk the tunnel with proper shoes and a torch. High recommended to visit.
