Lillsjön is the most popular bouldering area around Norrköping. It is located in a beautiful nature reserve around the Lillsjön lake. Its extraordinary location provides to Lillsjön very nice sceneries and the possibility of having a swim after climbing in the hottest days of the summer.
The sectors consist mostly of cliff-walls, but there are also some individual boulders scattered. Most of the problems are vertical walls and slabs but there are some overhang problems too. The rock is fine grained granite of very good quality. Some of the sectors have pretty high boulders but the landings are generally very good.
Most of the sectors are located deep into the forest and are prefect for climbing during the summer but they tend to dry quite slow. Some sectors, like Messias or Vollivoxa, have less trees around and dry faster. Due to the high humidity of the forest, the moss grows pretty fast so it is advisable to bring a brush.
There are problems with all the grades but the most of them are from 5-7a. Some of the most recommended problems are the following:
3 - 5+ : Femman, Höger, Hope you like jamming or Haleluja.
6a - 6c+ : Skrapet sittstart, Erik ditt lilla ollon, Triumfator or På en höft.
7a - 8a : Olles sloop, Relationsrådet, Svenskt stål or Morsans piasava.
