About 6 routes on a wall near the City Sports Complex and an amusement park!
The bottom holds were missing and the wall was seeping (it had rained the day we went), but wee were told it would be re-opened for the season when the weather improved. When opened the public hours are: Wed-Sat 1:00-10:00; Sunday and holidays 9:00-6:00; the last Tuesday of the month: 9:00-6:00. The wall is also used for special programs and classes. Day use is W1,500 with various membership packages. The back of the wall sports an artificial waterfall!
Several busses, including the 9, 56, & 95 run from Sosa Station to the wall. It's just past the Sports Complex and Stadium, in front of the amusement park.
More than every amenity is available nearby, except perhaps shade! It could get crowded during the peak season, but probably a good way to meet climbers!
