Aviapolis is a small crag consists of two areas, one being Pyhtäänvuori and the other being Karhumäenkallio. This is not a great place for bouldering, 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 with rock quality varying greatly from sharp to decent. 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...
