About this audio guide
Trübsee, the alpine lake below Titlis above Engelberg, looks like an ordinary postcard mountain lake. This guide follows the nineteen sixties engineering project that turned it into something else, along with the earlier decades when the same lake was simply a tourist destination, reached by cableway since the nineteen twenties. Best heard standing at the shoreline, looking out across the water toward the mountain behind it.
