hiking
Ulsan is the gateway to Gajisan National Park and is accessible from Eonyang, a suburb of Ulsan. Take a bus to the Eonyang terminal and change for a bus heading to Seongnamsa. Hiking in the numerous mountains around the city is very popular, especially among the Koreans. Just about any wooded area will be flush with hiking trails.
The city has a fabulous river park with walking, running and biking trails. Flowers are plentiful and make for pleasant journeys along the river.
