The climb over Sineosan hill is a tough one. For the first 2.5 kilometer of this hill, you’ll ride over rocky gravel, rideable with a road bike. When the road kicks up, you’ll have to conquer over a kilometer of concrete road with a grade of over 15%. The next stretch of road is pretty: beautiful new asphalt in the forest takes you – with some ups and downs, twists and turns – over the northern side of Sineosan hill. After one more climb, you return to Busan on the quieter side of the Nakdong river bike path.
