Aviapolis is a small crag consists of two areas, one being Pyhtäänvuori and the other being Karhumäenkallio. This is not the greatesr bouldering spot, but it has some decent problems. The best thing about this place is it's ease of access.
The Pyhtäänvuori area is what I would call the "Main sector", and it contains a single long sector, with mostly good rock quality and varying landing quality. Mostly overhanging and vertical problems, but a few slabs as well. The walls are quite short, the tallest part being only around 2.5m tall. Some problems are surprisingly good nonetheless. This sector is a hundred meters into a forest, and thus is more private and has shade.
Karhumäenkallio consists of multiple smaller walls and rocks. Walls are mostly vertical and 2-3m in height. The sector is basically in a park and is visible to onlookers. The rock quality is absolutely horrible on most walls, but Näyttämö, Hemomeisseli and Lohkareluola have good rock quality. Not a ton of shade here. The surroudings have some trash due to the urban environment. Part of it was cleaned by first ascentionists, but a lot remain...
