Traveller notes on Cradle Mountain in December
Other months in Cradle Mountain
Cradle Mountain's forum is blunt that January weather is genuinely unpredictable — regulars say to expect all four seasons in a single day regardless of what the calendar says, and to pack layers, a warm jumper and a wind/rainproof shell even in the height of summer. It's even been known to snow in January, so don't assume the forecast holds.
