For travelers looking to go off the beaten path in Israel, there are several secret underground tunnels to discover, granting visitors a peek into life during ancient times.
Hezekiah’s Tunnels (aka Siloam Tunnels)
Beneath the ancient City of David, travelers can explore the underground mysteries of Hezekiah’s Tunnel, where water has flowed since the time of the prophets. When Jerusalem was preparing defenses against the approaching Assyrian army in the eighth century B.C.E., King Hezekiah decided to protect the water source by diverting its flow deep into the city with a tunnel system.
Today, guests can still trek through Hezekiah’s Tunnel in knee-high water to peak into the world of Herod and the Second Temple period in Jerusalem.
Western Wall Tunnels
First discovered in the 19th century and uncovered after 1967, the tunnels allows visitors to travel back to the first century CE to discover ancient Jerusalem during its glory days. The underground tunnels can be accessed by a guided tour where guests can walk subterranean spaces with archeological findings such as large stone arches, water pits, an underground synagogue, an ancient water aqueduct that ends at the Struthion Pool, and more.
Herodium National Park
In the first century BCE, King Herod created the structure, Herodium. The manmade hill is located southeast of Jerusalem in the Judean desert and served as King Herod’s luxurious summer palace and his burial site. Guests can visit the fortress to explore the underground systems which include remains of a water tunnel from the time of the Great Revolt and escape tunnels from the Bar Kokhba Revolt.
Rosh HaNikra Grottoes
Located in the Upper-Galilee, Rosh HaNikra Grottoes are characterized by their beauty and turquoise color that changes during the day and seasons. The grottoes are cavernous tunnels that formed as a result of a geological and biological process that has been going on for thousands of years due to the power of the sea.
This attraction became accessible to the general public in 1968, when a tunnel was excavated to the natural grottoes, slightly above the sea surface. Visitors can explore the grottoes and caves by themselves by following a trail.
