Kasa Grande is a compact area located in Siuntio only around 30 minutes from Helsinki city centre. The area offers something for everyone, starting with grades at 3 and stretching to 7Cish. Kasa Grande has a large variety of different climbing styles, from overhangs, almost roof like climbing to super sensitive slab climbing, but the most evident style is vertical climbing or slightly overhanging climbing on crimps. The rock quality is mostly typical granite, some better some worse and offers good friction, but there is also one face that is black gneiss.
The area in general is drying fast after rain, with a few exceptions. But most of the crag is usually dry either within hours after rain or at least the next day.
It's hard to recommend single climbs in the area, because it has a lot of gems around.
Follow the recorded paths for easiest approaches and to keep the nature nice.
