Mikkelänkallio is a wonderful small crag in a nice surrounding suitable for the entire family.
With a short nice walk less than 5 minutes from the parking you'll reach the first rock. This one is a typical "rapakivi" boulder and therefore isn't really that interesting. But just behind this one, you'll find the main face. It's mostly fast drying, but some spots might be wet for a longer time. The long rock face is divided in two parts for easier climbing guide usage. The rock quality is excellent gneiss and the height of most problems are 3 meters or less with easy topouts. Landings are all good. You can find everything from really easy child friendly slabs to an extremely hard crimp problem most probably in the 8th grade range.
As always, do behave according to good climbing ethics, leave no trash, brush of tick marks, don't play music, etc. Be friendly to other people in the forest. If trash from other people is found, take it with you.
Park on one of the parking spots shown. Remember that the street parking is restricted to 4 hours (until 18 o'clock and usage of parking disc is mandatory). The other parking is 24H. It's about the same walking distance from both.
ps.the approach is not directly stroller friendly. It's a good path in the forest, but can be a bit tricky with a stroller.
