No. It's in the desert, all the way to the right of the map (left on Wii version). It's the part where this bridge is standing vertically in the ground, and Midna has to warp it to the east of Hyrule Town (west on Wii version). After Midna has warped it to another location, you can go in the tunnel where the part of the bridge was. Prepare yourself and don't go without enough supplies (healths, arrows, bombs, other items).
Finished it....
It was trippy... but I made it without getting myself killed.
