Käärmekallio is a city crag in Vantaa. It has many easy and well protected routes between grades 3+ and 6a. The place is a little noisy due to Kehä III traffic but not insufferable.
There are two sectors: the old "Wanha Käärme" in the forest and the new "Aurinkokäärme" släb. After rain the slab dries almost instantly if it's sunny. The forest sector, however, takes about a day to dry up. Some routes are dripping and may take even longer.
Käärmekallio was developed for Finnish Climbing Association (SKIL) educational purposes in the 1990's. These days you can still see a lot of educational activity but Käärmekallio is also popular among recreational climbers. It's also popular with families since there are many good routes for kids.
Many of the routes were bolted in the summer of 2010. The second batch of progress was during the winter 2019-2020. During the dark days of that winter, nine previously dangerous routes got shiny new bolts. Many new anchors were added as well.
