Stadikka is a very small crag smack dab in the middle of Helsinki, in the Eläintarha area. It has 11 routes, ranging from grade 3 - 5. Do not let the grades fool you though - the climbing is extremely good despite of the grades being relatively low. This is mostly because of the rock quality - the absolutely hypnotic, nearly sandstone like wavy quality of it. There's not much like it in Finland, especially in the Southern parts.
The sector is quite tall, around 4-5 meters high. The profile on the right side is quite slabby, while the taller left side is pretty vertical. Stadikka is relatively well shaded, and despite it being located right next to a path the sight-lines are blocked by foliage, so you can most probably climb in relative peace.
The condition of the crag is pretty good for the most part, but the three routes on the right side have grown a heavy layer of moss. Take a brush with you!
