In the mid-part of Korouoma, below the surrounding terrain, the fracture valley forms a gorge, whose cliffs are steep and, in places, vertical and dozens of metres high. Areas formed by huge boulders of rock and rock have remained open from vegetation and are an impressive sight at the bottom of the valley.

Many attractions are along the Korouoma hiking trails, Koronjää and Piippukallion pihaus day hiking trails.

Koivuköngäs Rapids

Koivuköngäs rapids is a four-meter waterfall in the northern part of Korouoma. The Koivuköngäs rapids is gently sloping and the water descends gradually, but with a stir. At the time of spring floods and the effect of rainfall in summer and autumn, the hoof looks impressive. Koivukönkgäs can be reached from Kurtankaltiontie, which is near Rovaniementie.

Saukko-oja Rapids

The height of the Saukko-oja rapids, located right along the Korouoma route, is 8 meters. The waterfall is steep, so the water is bubbling and the noise is loud.

There are also more rapids in Korouoma area.

Piippukallio Rock

Piippuköngäs Rock on the western slope of the Korouoma Valley offers a magnificent view over the valley.

In addition to the Piippukallio Rock, there are several observation decks on the western slope, from which it is worth stopping to admire the opening scenery.

Frozen Waterfalls

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:


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


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


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
