When the first small drop of water falls over the edge of the dam, its foaming journey towards more spacious waters, towards the great lake of Ladoga begins. It first foams in the Imatrankoski Rapids and tries to escape the great water masses that follow. The drop swims under the old lanterns at Koskisilta Bridge. It spins past the idyllic Pavillion. It passes the venerable Valtionhotelli hotel and a rock cliff that in the past held a squeaky ropeway. It sprays some moisture on the guests standing at the viewing terrace and surges towards the centuries old rock engravings, the royal graffiti.

And this is how the water masses accumulate. They fill the rugged channel; they spin, agitate, thunder. 

Visitor to Imatrankoski: If you have never heard the thunder of the rapids, experienced its magnificent force, now is the time. For a moment, you feel you are held tightly in the violent embrace of nature. For a moment, you feel you are one with history, with the ancient river bed. 

That experience is just as large as the smallest drop of the foaming rapids.

The Rapids shows in 2024:

  • June 26 - August 31 from Wednesday to Sunday at 6 PM

The Rapids show lasts approx. 16 minutes. Eight minutes after the flood gates are opened, the foams reach their peak with an average of 400 cubic metres of water per second flowing in the stream. In the summer rapid shows will be accompanied by music of Jean Sibelius and on Saturdays the Whitewater Symphony by the Osmo's Cosmos band. 

The best places to watch the Rapids shows are Koskisilta Bridge and Koskipuisto Park.

During the summer season, guided tours are organized in the Kruununpuisto (the park surrounding Imatrankoski). You can inquire about your own guide for groups from Imatra Tours.
