The cache is located just off one of the main walking/skiing trails leading into Tillinmäki forest. You will need to take a smaller path to reach the cache site.
You are looking for a standard container. The surroundings may cause the coordinates to spin so do use the hint if you need to narrow down the location a little. There is definite erosion, but this pre-dates the cache. Please ensure that it is well-hidden again after logging.
