Some people have asked about public bus services to Wuling Farm - the base for hiking the main peak of Snow Mountain. From Yilan City: buses leave at 7am and 12:40 and take about 3 hours. From Taichung (remember a major part of the Central Cross Island highway is still impassable): Fengyuan bus company has a bus leaving at 8am arriving at Wuling at 4:30. A long ride but traveling the highest road in Taiwan.
Driving from Taipei only takes about 3 hours through the 13km Hsuehshan (Snow Mountain) tunnel via Yilan. For those of us in the South/Center the journey is torcherous; whether we travel the shortest windiest way via Puli/Hehuan shan, across the almost as bendy and foggy North Cross Island Highway, or just stick to the long boring freeway via Taipei and Yilan.
