Julma-Ölkky

Julma-Ölkky is the largest of the three canyon lakes in Finland, in a deep crevice. The birth of Julma-Ölkky dates back to more than 2 billion years ago, when the surface of the Earth was formed.

The length of Julma-Ölkky (Ylä-Ölkky on the map) is about 3 km, and it is about 10 m wide at its narrowest point. Its depth is 50 m. At the highest point, the rocks are about 50 m high. After the narrow section, the crevice continues for a further 500+ metres, first as Pikku-Ölkky and then as Ölkynlampi, after which the crevice widens out and the shores become shallower over the course of 2 km. Ölkynpuro-stream flows at the bottom.

You can explore Julma-Ölkky on a guided boat tour, hiking on the trails or by renting a canoe. The surrounding nature is also excellent for winter activities such as snowmobiling, snowshoeing or skiing.
