On the erratic boulder trail

Enormous erratic blocks can be found between Monthey and Collombey. Deposited there a long time ago by giant glaciers, they bear silent testimony to the forces of nature and have been sparking debate among climate researchers for years. Eight information boards relate the history and origins of these protected blocks of stone.
