Cradle Mountain, Tasmania Activities Hike at Waldheim Chalet Nestled among the myrtles and King Billy pines at Cradle Valley, Waldheim Chalet takes you back to the time when the Weindorfers first offered their renowned hospitality to their guests. Having fallen in love with what is now Cradle Mountain -- Lake St Clair National Park, Gustav and Kate Weindorfer built the rustic home and guest chalet in 1912.
