Upstream to the right of the crossing under the railroad tracks is the southern entrance to the Kerem Tunnel. The tunnel connects Nahal Refaim and Nahal Sorek. It was excavated as an infrastructure tunnel and was used for the Jerusalem sewer line to transfer sewage to the desalination plant in the lower stream of Nahal Sorek. In 2018, the tunnel became a bicycle tunnel and welcomed the first Jerusalem international bicycle ride. About six and a half thousand cyclists participated in this ride. As of September 2022, the tunnel is open for riding as part of the Jerusalem bicycle Trail. The tunnel is the fifth largest in the world for cycling.
This day trip in the Judean Mountains south of the Jerusalem Mountains reveals hidden wonders surrounding Israel's capital. At the centre of things are Nahal Rafaim and its surroundings. We will start with a spectacular view over Nahal Refaim, go down to Ein Itamar, reach Ein Lavan, cross the stream, and visit Ein Haniya. Then, for dessert, we will go to the highest mountain in the area, Mount Gila, and learn the history and story of the place. The most recommended season is spring, the month of March, when the almond blossoms, primroses and lupines, lavender and Lof blossom, anemones and orchids hide between the rocks. Have a nice trip!
TIP: It is better to travel in two cars in a friendly company, leaving one car in the parking lot of Emek Refaim Park and getting to the start of the route in the other vehicle. Then, having completed the walking part in Ein Haniya, return to the car in the parking lot in Emek Refaim Park, rejoin the first car and climb Mount Gilo together and complete the route. Of course, travelling independently to any point on the road is possible.
