The cache is hidden in the forest nearby a public playground. It's available at all times. But mind the ice in the winter, it may get slippery!
The name comes from the nearby roads Kuurutie and Piilotie (kuurupiilo=hide and seek), and the playground (leikki=play).
No need to enter private areas.
UPDATE THE COORDINATES/GEOCACHE, SINCE IT SHOWS THE OLD COORDINATES INSTEAD OF THE NEW ONES!!
