If you have the standard sized Zelda Symbol Dog Tag, a compass, and a map you'll be able to get to the 5th Dungeon there towards the upper right of the map! You know...where you have to move that left block in that diamond of rocks. Yeah, I can tell by that gleam in your eye you know what I'm talking about! Based on the Skyward Sword installment, the Zelda Symbol Dog Tag is an essential part of your equipment.
