Huopanankoski

[1] The rapids became famous due to the Finnish author and journalist Juhani Aho, who wrote popular short stories of his flyfishing experiences there.

The rapids consist of a narrow forked stream flowing from Lake Vuosjärvi to Lake Muuruejärvi with a total elevation difference of 6.5 metres (21 ft).

The Huopana village is situated at the lower part of the rapids.

The fishing season runs from January 1 to September 10 and from November 16 to December 31.

The natural catch species are brown trout, ide, grayling and whitefish.
