Taiwan in Cycles and another friend, Andrew, and rode a little loop out of Shuili -- up 131 and over to 21, around the corner of Sun Moon Lake to Ita Thao (Dehua Village), then south out of Dehua Village on Nantou 63 back to 16 and Shuili (map).
The picture above I took from a scenic spot on Nantou 63. It utterly fails to do justice to one of the most beautiful moments of my life: after lunch in Dehua Village, we followed the switchbacks up Nantou 63 to 800 meters, surmounted the ridge above Sun Moon Lake as it began to rain, and then beheld the utter glory of Taiwan at its most beautiful, the interplay of gentle light and rainy cloud in the deep mountains framing a classic alpine descent of switchbacks through farm, forest, and field down to Route 16 and the Choshui River. Pure biking heaven.
ADDED: Drew's excellent account.
