Very varied trail through different parts of the sandy dunes, pine forest, along a bog... Lots of information boards (in Finnish and Swedish only). Marked with green diamonds and sticks painted green (or just white) at the top, but only in counterclockwise direction.
There is one diamond mark that looks like it's going off the dirt track (that's parallel to the main road) into the forest - keep following the track instead, then turn into Ruukintie.
