Korouoma Nature Reserve Trails

During a forest fire warning (ilmatieteenlaitos.fi), fire is only allowed at covered campfire sites that have a flue or in fireplaces at huts, but only with extreme caution. The one who lights the fire is always responsible for its safety. Making a fire at campfire sites can be banned locally.
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.
