In the Hedge Maze once again, you will find that the guards are now gone from the maze. This will allow you to collect the rupees you skipped earlier, and collect the Maiamais and Heart Piece as well if necessary. Our next destination will be in the northwest area of the map. So, use Irene's Bell and return to Thieves' Town.
Thieves' Town
Here again, use the fissure portal in the hollowed out house to return to Hyrule. Once you do, go to Sahasrahla's House and use the fissure portal behind it to return to Lorule. Once you return, go east and north one screen each, past where the Fortune Teller's tent was in Hyrule (in Lorule, it is behind the Blacksmith's Shop), and enter Skull Woods.
Skull Woods
In the forest, you will quickly find that it's more of a maze than the Hyrule version for sure. Go north and you will reach a weather vane to activate/save at. Do so, then enter the nearby giant skull head to start the next dungeon.
