Eestari/Eestinkallio is a small, relatively suburban crag with two main sectors and a small additional boulder. The approaches are short, and Eestinkallio is easily accessed with public transport. The main sector, Incredulity, has amazing rock quality and high quality problems. It has x problems ranging from grade 4 - 7A. It is very well shaded, but a decent portion of its' routes don't have a quality landing, so multiple pads are recommended. Sadly, the main sector is quite mossy at the moment, but the problems are well worth the brushing!
The second larger sector, Pommituksen Keskellä, is a ~3 m tall slabby face with good rock and very interesting crack features. It has x problems ranging from grade 3 - 6A+. Climbing is mostly technical slabby stuff on crimps, but there are a few exceptions. The landing there is absolutely perfect. The sector was recently brushed, so most problems are ready to climb! Pommituksen Keskellä is basically right next to some residential buildings, with no trees or anything to block sight-lines, so remember to be cordial, greet the locals and explain yourself when asked.
Firestone is the third sector, located in the forest and requires a bit of bushwacking to access. It is a small freestanding boulder with four short and powerful climbs between the grades of 6A - 6B+. Very sadly a tree has been felled in a way that it partly blocks access to some routes. If you have herculean strength (or a saw), you can help the climbing community by moving some pieces a bit to the side.
Some recommendations on routes:
Incredulity, 7A: A very technical and mental slab, that still looks quite futuristic all these years later.
Purista, 6C: A technical slabby traverse on tiny holds and a scary topout.
Vokatiivi, 6B+: A mental battle and a hard mantle on mostly good holds.
Kodak Fever, 6B: A pumpy endurance testpiece with perfect holds and rock quality.
Hold the Line/sit, 6A/+: A nice crimpy line on perfect holds.
Eestarin Pommi, 5+: An amazing dyno/deadpoint that static enjoyers can static their way through. Same grade both ways!
Kristalliportaat, 4: An easy warmup on unique pockety holds and huge quartz steps at the beginning.
