Woods Treescape is a natural maze protected by the Sage’s magic.
Unless you leave the map via the “Main Entrance” or the Sage’s Hamlet entrance, you will end up at the same Mila Shrine. (You can find some Mana Herbs here as always.)
From here, you can head north, east, south or west, where you will emerge from the opposite entrance (eg. going north from the Mila Shrine will take you to the South Entrance).
