In the Bavona Valley, where a large amount of energy is produced (three power plants; three reservoir lakes), there is no electric current, with the exception of Robiei. Therefore, solar cells, gas, small water turbines, candles, petroleum, etc., have to be used instead.
Seerenbach Falls and the Rin Spring
A forest trail leads from Betlis village to a vantage point, opening up a vista to a gigantic water spectacle. The Seerenbach thunders over the vertical cliff face on the northern shore of Lake Walen, cascading 585 m in a series of stages down to Betlis to join the waters of the Rin Spring.
