Once the last snow has melted, one of the most enjoyable ways to explore the Alps is on two wheels. The Wilder Kaiser region in Austria features trails for families and daring mountain bikers alike. It’s also home to the world’s largest collection of electric bicycles, with 275 rental bikes and 75 charging stations. Stop by one of the rental shops in Ellmau, Going, Scheffau, or Söll, charge your battery, and then zip down well-built cycling paths, past 45 different villages. Those keen to pedal on their own can opt to explore the area with a guide from GoingBike, a professional outfitter offering tours and training for both children and adults.
