On duckboards you will walk through the reed. Once you are deep in the reed you could forget that you are in Helsinki. It is like a little trip somewhere else.
Come prepared: depending on the water level you might need rubber boots. Sometimes the duckboards are flooded. Sometimes it might be impossible to get to the cache from every direction. The entrance closest to the cache is recommended.
Be careful: the first version of the cache disappeared quickly after publication. Please make sure you are not being watched as your search might appear suspicious for muggles. The area is relatively frequented by people jogging or walking their dogs.
The cache is a micro container that can be reached without leaving the tracks. Please put it back carefully.
