The underground city is open to visitors, who can use the same underground tunnels that residents would have used 2,000 years ago. The most notable tunnel in the area is Hezekiah’s Tunnel. He constructed tunnels to bring water to the people within the city walls; this is even quoted in the Bible: “the acts of Hezekiah and all his might, and how he made the pool and conduit and brought water into the city” (2 Kings 20:20). There are two other major underground systems in the area: Solomon's Quarries and Solomon's Stables.
Guided tours take visitors to explore the tunnels of Underground Jerusalem: touring with a guide is the only way to visit and your exact experience will depend upon your selected tour company. For those short on time, a combination tour that includes Underground Jerusalem along with a tour of the city’s above-ground historic sites is a good option.
