Maarianmaan puisto has a wealth of boulders and rock faces. The park consists of two valleys. The rock quality ranges from completely smooth to painfully sharp and everything in between. Climbing includes everything from overhangs to slabs.
The park itself is great with kids, and the harder boulders are hidden in a forest on the north side.
It is also very near a local swimming area, Pikkukoski
Note that because of the micro climate in the valleys, it is about 1-3 degrees warmer in Maarianmaa then in the surrounding areas. Also, there is very little wind.
