The Dolomites have some of the finest landscapes anywhere in the world. The Passo Gardena is part of what is generally known as the Sellaronda Loop, which includes the Campolongo Pass, Sella Pass, Passo Pordoi as well as the Passo Gardena, also known as the Grodnerjoch. 
The Sellaronda is arguably the world's most beautiful cycling route and host to the Sellaronda Bikeday and the short course of the Maratona dles Dolomites sportive.
