Ugrikivi is a nicely formed boulder with pretty good rock quality and some nice holds on it. It's got some highish problems and some low stuff as well, and the routes vary from low overhang to highish slabs and vertical routes, so there's something to do for everyone here. And overall quality of the routes is pretty good too!
Height of the problems vary between 2-5 metres and the landings are safe. So there are plenty of problems for beginners and those scared of heights as well.
It's on a partially harvested nice forest. The rock dries relatively quickly. A lot of the routes are hiding from the direct sunshine, making it a good choice for summertime bouldering as well.
Specially recommended routes are:
"Natsiromanssi", one of the highest routes here - really nice!
"Bestiario" and "Kimmostoliitto", both really nice short overhangs!
"Vähäsen Muhkumpi", an easier sibling to Natsiromanssi, nice technical climbing.
"Metsien Kim Kardashian", low but really nice piece of rock.
