Caving in Finland

Finland is hardly a country known for its caves

Unisvuoren Susiluola, Nousiainen. (C) Jan Nyström, 2014

The bedrock comprises mostly granite and other insoluble stones and there are no major karst regions suitable for cave formation.

A handful of limestone caves do exist, but they are small. The longest accessible limestone cave, Torholan luola (Torhola cave, on Karkalinniemi near Lohja), is only 83 meters long.

In addition, there are countless glacial boulder caves and tectonic-glacial crevice caves and rock shelters, over one thousand in total, although these tend to be pretty small. SRT is probably not usefull in any but possibly one crevice cave (Olhavan vuoren luola, ten metres down) and diveable caves we do not have. The longest boulder cave in the country, Repouuro (260-280m surveyed length) near the Koli mountain is our only “showcave”: guided tours are operated by Koli Activ. Free entry if you find it though – but it’s a maze too. The likewise confined Korkberget boulder cave in Kirkkonummi near Helsinki also boasts nearly 300m of surveyed passages. In the city of Turku there is a cozy (dark) little boulder cave, Luolavuoren luola, offering crawling and optional committing squeezes for those so aligned. It is conveniently accessible by city bus and located on the slopes of a wooded hill next to and amidst residential areas. We recommend the blog as the first source of information.

A cave that fits two or three people comfortably is fairly sizeable by Finnish caving standards.

Finnish caves can typically be visited with a minimal amount of equipment: helmet, head torch, and durable clothes are typically sufficient. It is not unusual to spend more time looking for the cave than actually exploring it.

Suomen luolaseura / Finlands grottförening / Finnish Caving Society

Finnish Caving Society is the one and only Finnish club focusing primarily on dry caves. The club was founded in 2010 and has been publishing a printed annual journal Luola since 2013. We neither organise nor train cave diving, but some of our members dive sumps and caves in general on some of our trips abroad.

For cave divers there are other organisations centered around a number of lovely diveable mines with bustling activity: Haveri mine (Tampere), Montola mine (Montola, Pieksämäki, Central Finland) and Ojamo mine (Lohja, South Finland).

The aim of our society is to promote cave-related activities and to increase public knowledge of caves and caving. The club has around 60 members, including both people who mainly visit, explore and catalogue Finnish caves and those who spend their vacations visiting large cave systems abroad.

The society organizes trips to both Finnish and foreign caves, offers training courses, provides online information on Finnish caves and caving, maintains a discussion forum, promotes cave surveying, publishes an annual printed journal, acts as a liaison between Finnish cavers and foreign clubs, and represents Finland in the European Speleological Federation.
