It is located in the middle of mountain with a very nice skyscraper view of the center of Busan, but you can get up there by 30 minutes walk from nearest subway station. It has fairy small space like 3m high X 7m wide and also has a outdoor artificial wall approximately 10m high X 7m wide, which opens from March to October. Usually you'll be able to enjoy the whole gym alone like a private gym- I myself like this kind of surroundings the most!
Indoor gym hours are 09:00 to 18:00, closed every Monday. Open on weekends.
Free of charge all year around.
Take the subway to Jeonpo station on number 2 line and walk out exit 6 and walk straight about 3m and turn left to the alley follow this alley till 동성고교(Dong sung high school) upon passing by this school cross street and you will see an arch saying Hwang Ryeong Mt Reports Park. Pass through the arch and walk up about 100m towards mountain. Gym is on third floor of a big three story building. By bus take the bus 82 or the community mini bus number 12 and get off at Jeonpo 3 street(전포 삼거리) right next to the arch where you can see the building on the mountain.
