Yovel Cave
Yovel Cave (Mearat HaYovel, lit. 'Jubilee Cave') is a massive karst cave located near the Israeli settlement of Ofra in the Benjamin region. It is recognized as the largest natural underground site in Israel. The cave was named "Yovel" (Jubilee) because it was revealed at the time the settlement of Ofra marked its 50th anniversary.
