Kerinkallio is excellent urban crag that hosts many types of climbing. Access to all sectors is quite easy and there is even children's playground next to main wall, so being parent is no excuse. Walking from train station takes about 20 mins or you can get a bus number 32 and hop off at Lepikonkatu bus stop front of YogaRocks. Those coming with car can find free parking area at crossing of Kerinkallionkatu and Kerintie.
At main wall of Kerinkallio, which is mostly slab, containing crags and small roof, there is sport routes from 5+ to 6c+. Also there is trad routes graded 4+ to 5+, some of them being partially bolted. One more sport route is waiting to be bolted and one trad route is not yet included into topo. Other sectors contains only boulder problems and those can be found in all angles and styles. Boulders are graded from 4 to 7B.
Main face and boulder slabs next to it are exposed to sun, so in hottest days of summer you may want to go more shady sectors like Isokivi, Pikkukivi, Rakokivi, Pikkuseinämä and Alaboulder, hänkki.
