The Gigerwaldsee and Saint Martin Switzerland

Saint Martin is only accessable in the summertime through a series of one way tunnels. Every 20 minutes, the traffic direction changes as there is barely enough room in the tunnels for one car...a small car. The sign above tells you what time you are allowed to travel which direction. This is a beautiful area west of Bad Ragaz, mountainous with thousands of waterfalls. http://www.sengers.ch/stgallen/gigerwaldsee/gigerwaldsee.asp
