The Wind Path is a gimmick that appears in the Sonic the Hedgehog series. It allows its user to move through the air without a solid path.
The Wind Path is, like its name implies, a road created from the fast movements of winds, thus forming an invisible path which is surrounded by swirling leaves all along it.
In Sonic Adventure, and its enhanced port Sonic Adventure DX: Director's Cut, the Wind Path is found exclusively in Windy Valley. Utilizing it in gameplay allows the player to travel through Windy Valley at high speed. The beginning of the Wind Path is marked by a rectangular gateway with several propellers adorning its rims.
To use this gimmick in gameplay, the player has to move into the gate marking the beginning of the Wind Path and hold the control stick forward. Otherwise, Sonic will slow down and fall into a bottomless pit.
