begun in the 1960s, covering thousands of hectares on and around the mountain. Since then, Spil Dağı National Park has attracted many foreign and domestic tourists. The famous "Weeping Rock" is still widely visited. The mountain as a whole presents an area of dense forests and is known for its wild tulips. The mountain is also a common spot for camping, parachuting, hiking and other mountain sports. The motorway connecting the two regional metropolitan centers, İzmir and Manisa, crosses between the two neighboring masses of Mount Sipylus and Mount Yamanlar through the Sabuncubeli Pass, which was much described by ancient travellers and writers and which descends from an altitude of 600 m to sea-level in only a few kilometers. The highest point of the pass corresponds to a point near the boundary between İzmir Province and Manisa Province. To bypass the steep and twisted Sabuncubeli Pass, the -long Sabuncubeli Tunnel was built from 2011 to 2018.
