Urkka is a nice compact crag of 2 boulders side by side. The boulders are shaded by trees, but they are on top of a little windy hill, so they dry relatively quickly. That makes them a good spot for spring and autumn sessions, but it works in the summer as well, due to the shades.
Rock quality is good, and approach is almost as easy as it can get, short walk on gravel and some 20 metres to the woods up the hill. The boulders are surrounded by nice forest.
Even if there aren't that much of problems, the overall quality is good. Try at least these when you're around:
Kannustinloukku assis, a superb overhanging arete
Turbo Muscle, also a really nice overhanging arete, only downside being it is preferred having at least 3 pads for this one.
Tango Delirium, a nice technical and delicate slab
