Charge up your electric car, your e-bike and your appetite - Lucerne and Central Switzerland are primed for high-voltage, low impact summer fun. Jeff hikes high into the pristine Alps, bicycles around a breathtaking mountain lake, goes panning for gold in a gorgeous gorge, and relaxes in a spa-like nature preserve. He strolls the colorful murals of Lucerne's beautiful old town and glides its azure lake in the country's first climate-neutral cruise ship. In the bucolic farmland of Entlebuch, Jeff follows the clues on the Marbach food trail, sampling organic local specialties at every stop.
