Diving in Lake Zug

Lake Zug, nestled in the heart of Switzerland, offers divers a unique freshwater experience. Among its highlights is the wreck of the Hirslanden, a fascinating site for those interested in underwater history. This dive is particularly captivating due to the preserved state of the wreckage, providing divers with a glimpse into the past.

For those who prefer shore dives, Lake Zug does not disappoint. The shore dive at Chiemen is a favorite, offering easy access and stunning underwater landscapes. While liveaboard options are limited due to the lake's size, divers can enjoy night dives that reveal the lake's elusive nocturnal marine life. This balance of shore and limited liveaboard experiences makes Lake Zug an intriguing destination for both novice and experienced divers.
