Sights at Korouoma Nature Reserve

28.11.2018
At Korouoma the route between Pirunkirkko and Julmakallio is now closed from visitors. The stairs at the route are in very bad condition. We will inform later about the repair schedule.

In the winter, the small streams pouring down the cliffs become frozen waterfalls. They remain frozen until late spring. Precipitation and sub-zero temperatures determine the number and shape of frozen waterfalls. Most people are happy to just admire the frozen waterfalls, but enthusiastic ice climbers climb up the frozen waterfalls to the top, despite the intensely cold weather.

You can see the frozen waterfalls at Korouoma by hiking the Koronjää Day Hiking Trail clockwise:

Revontuliputous

The ice in Revontuliputous (the Northern Light Fall) is often flaky and the ice layer thin, as the water usually only runs in late autumn.

  • Height of the wall: about 40 metres
  • Width of the wall: 5-10 metres
  • Steepness of the wall: 80-90 degrees
     

Tuulen tie

Sections of short frozen waterfalls on the cliff, trees are growing on top of the cliff. There are snow-covered stones at the foot of the cliff.

Tuulen tie (the Winds Way) has thin, finger-like formations of ice, most of them vertical. It is not suitable for climbing every winter.

  • Height of the wall: about 40 metres
  • Width of the wall: 80-100 metres
  • Steepness of the wall: 85 degrees
     

Jaska Jokunen

A tall and wide uniformly frozen waterfall on the cliff. There is snow and trees in the surroundings.

The water usually only runs to the Jaska Jokunen (Charlie Brown) icefall in late autumn, and the ice is thin and flaky most years. Some winters, the middle section of the wall turns into an ice cave that lends itself to an adventurous overnight stay.

  • Height of the wall: about 50 metres
  • Width of the wall: 20-60 metres
  • Steepness of the wall: 50-90 degrees
     

Onnekas

A narrow frozen waterfall on the low cliff face There are trees in the surrounding and snow-covered rocks in the foreground.

The Onnekas (Lucky One) icefall forms infrequently. It is located about 100 metres upstream along the River Korojoki from Mammuttiputous (the Mammoth Fall). 

  • Height of the wall: about 50 metres
  • Width of the wall: 20-25 metres
  • Steepness of the wall: 80-90 degrees
     

Mammuttiputous

A wide and tall frozen waterfall on a tall cliff. There are trees on top of the cliff, trees can also be seen in the snow in front of the cliff.

Mammuttiputous (the Mammoth Fall) is one of the most popular climbing spots at Korouoma. The wide frozen fall offers several climbing routes of various levels of difficulty. The right side of the icefall is some 50 metres high, and the width varies from year to year. The brook that creates the ice originates on the slopes of Yli-Voho Hill. Most of the brook's clear water comes from a spring, which gives the ice sheet its distinct blue colour.

  • Height of the wall: about 35-50 metres
  • Width of the wall: 40 metres
  • Steepness of the wall: 50-90 degrees
     

Ruskea virta

An ice wall in the middle of an uneven cliff face. There are trees both on top and at the foot of the cliff.

Ruskea virta (Brown River) at Piippukallio is Korouoma's largest and highest icefall. As the highest frozen waterfall at Korouoma, it poses a challenge even for more experienced ice climbers. The middle area routes rise to about 60 metres. The water flow is strong all through the winter, and if the frost sets in early, you can go climbing at the turn of October and November. The last pieces of ice usually disappear at the turn of May and June.

  • Height of the wall: about 35-60 metres
  • Width of the wall: 40 metres
  • Steepness of the wall: 70-90 degrees
