Broken Bridge - Out of Bounds

Entrances
Once you're in the northern OOB area, it's easy to get to the east and west sides by heading through the top of the windwall.

Over the wall
Perhaps the easiest way to get into any out of bounds area: fly over the invisible wall north of the Shrine. Easily done through charge boosting.

Cow Sands
An area where the sands have dark spots on them, resembling the spots of a cow.

Floating Chirp
If you travel to the southeast corner of the map without Chirping, you can see your Symbol, floating below the map. The symbol disappears as soon as you release a chirp.
