Best hiking routes in Busan.

Highly recommend the Oryukdo Skywalk. It's 5 km long and takes about 2-3 hours to walk, rest, and take photos. The scenery is really nice. PS: There are mosquitoes, so it's best to wear long pants. There are no restrooms or supply points in the middle. You need to climb stairs and go down steep slopes. If you don't usually climb mountains, be careful. Oryukdo Skywalk
