About Spiezwand
Spiezwand is a boat-access freshwater wall dive on Lake Thun above Spiez, known for a dramatic drop lined with submerged trees. The site is most rewarding in winter, when colder water usually brings clearer visibility and makes the tree-covered wall easier to read. Divers come here for the scenery and structure first, with pike and eels near the trees and much lighter fish life in the cold season.
