Welcome to Omashu! Located in the Earth Kingdom, this mountain city is world-famous for its stunning vistas, cosmopolitan culture, wacky government, and most of all, its unique mail delivery system. Earthen mail carts are brought up the mountain with earthbending and sent downhill via an impressive network of sloping troughs. These delivery troughs, according to Avatar Aang and Former King Bumi (RIP), double as the world’s greatest superslide!

So if you’d like a varied taste of Omashu’s culture and an adrenaline rush, follow in the King’s footsteps and go for a ride!
