Maybe the best route in Ristivuori is the steep dihedral Onan Barbaari.
After or before climbing we recommend visiting Kustavin Savipaja, an artisan center with a nice café.

Once upon a time, Ristivuori was visited by the author Voltter Kilpi, who used meditate on the top. In Finland he is famous for his untranslatable massive novel Alastalon Salissa, which is set in the 19th century Kustavi.
Climbing was introduced to Ristivuori during 2019.
