From Zelda Legends Wiki
This mini dungeon is in The Legend of Zelda: Oracle of Ages. It is the only way to gain acces to the Maku Tree at the beginning of the game. There are two versions of this dungeon.
The present version of the Maku Road is the first one to be entered in this game. It is quite a straight forward dungeon and has no turningings. On the ingame map it looks like a straight path, but there are several puzzles involved, although none of them are difficult.
In the past it is slightly more complex, although not much. I has slighly more puzzles, a locked door and a key.
As you can see from the two images above, the changes to this mini dungeon are not that great. There are 4 rooms in the past version of the dungeon that are unaccessable in the present. All of the signs in the present version say "Danger!!"
