Haaga hosts fair amount of climbing, specially enjoyable climbing around 7a-7b level. The rock quality is solid. SGT sector has very good smooth and solid rock texture, opposite of OIKEA wall where it gets sometimes little sharp. All of the routes above 6c+ in the sector can be considered as highballs. Most popular routes in the last years have been Kemiallinen venyttely, 7a Vekkula 3000 7b, Risuranne 6a + and Jorma 6a+. That being said Jerry and Cosmic Mindfucker should also gain more popularity.
Haaga is a true oldschool bouldering spot in an urban park close to downtown Helsinki. First boulders were developed in mid the late 80´s when crashpads were not even invented. Considering that most of the classic lines on the main wall are pretty high even by todays standards it is quite impressive that they have been climbed with only a towel underneath!
Pioneers of Finnish climbing scene used to train here for "real" climbing. Top picks from the old boulders include Cosmic Mindfucker by Kari Poti, Fakiiri by Henrik Suihkonen and Jerry by Harry Hakomäki.
Unfortunatelly the cliff has seen some minor chipping later on, maybe after 2010. Luckily it seems only one hold is made better making Cosmic Mindfucker and Tigris somewhat easier.
The walls have been partly covered with graffiti as long as climbing has been done, making some of the footholds extra slippery. New layers of paint appear every now and then but the lines should stay the same, so please no chipping in the future.
