The cache is hidden between two lakes, Suuri-Kohi and Kohmavesi. Suuri-Kohi is three meters above the level of Kohmavesi, so there is a small stream between the lakes. If you're coming for a picnic, there is a nice campsite just by the lake at coordinates N 62° 47.410 E 28° 14.084.
You can get pretty close to the cache by car from the direction of Kohma village. If you come by boat, you can leave it close to the campsite.
The box is a normal film container and has pretty much nothing but a logbook and a pencil. It should be possible to find it also in wintertime.
