Havukallio is one of the oldest and best rock climbing sites in Finland for a trad climber. Havukallio has many stellar crack lines especially in the middle grades. Havukallio is also very high by Finnish standards with many routes about 20-25 meters of height on it's 200 meters of width.
Havukallio is know for it's vertical cracks which range from 4 to 8a. The most known and distinct of the crack routes is most probably Ee-mäntä (6c+). It is an overhanging challenge with a wide crack in the middle. There are also many other high class routes in the 6a/6b range. The easier routes near Keväthuuma are also of high quality and very popular.
Havukallio faces south and dries quite fast. Some routes such as Snellman tend to drip longer, though. The big trees in front of the cliff make climbing possible also on those hot days.
