About
The River Orbe created a fascinating cave system at the Vaudois town of Vallorbe. The tour leads visitors along the subterranean course of the Orbe (an outflow from the Vallée de Joux), passing by stalactites, stalagmites, drip-stone formations, columns and galleries. Once upon a time fairies that charmed young men were supposed to have lived here.
