Beautiful sunny day, perfect for a spin out looking for some dirty paths. Through a somewhat usual Mustikkamaa -> Herttoniemi -> Viikki route I ended up in Koskela and by complete accident wandered upon some beautiful hills with delicious rocky paths, clearly some of them used for riding. Need to go there again, time was limited this time!
