Grab your helmets, headlamps, and a spelunking friend for a cave diving adventure in the Swiss Alps for this Geocache of the Week. With high peaks and the beautiful Walensee it’s easy to see why people come to this location, but cache owner, tuxracer, had their eyes set on something else. Deep below the skyscraping mountains and glimmering alpine lake is a vast underground cave formerly used for mining. A perfect opportunity for an ambitious D5/T4 geocache with an Indiana Jones feel.
