The Dead Tree of Ranchiuna (HP)

After unlocking the Drizzly Path achievement, it will be 16-18 more minutes of walking until the train appears. After spending some time in a cave (back up a bit and wait for some boards to fall when it seems you have reached a dead end). Next comes more walking. When you see a watch tower ahead, go towards it if you are interested in the colorful ghosts story, otherwise go left. You will come to another large make-shift shack. Take the path uphill to the left and pass a lonely cow. Not too much farther now! Be looking slightly up or you might miss the train! (but not the achievement).
