From the most unforgettable 2007 experience thread:
I would love for you to start a thread with more details on this[/quote]
OK, here it is, stu.
There are 2 ways to do this: clockwise, which goes from Taipei to Yilan on the beiyi highway (Rt. 9) on the first day, and then day 2 from Yilan to Wulai via Tonghou and then back to Taipei. Or counter-clockwise, which is the same loop in reverse.
The advantage to the clockwise approach is you can also include the running horse trail (paomagudao), another off-road trail that goes from Rt. 9 down to Jiaoxi, a suburb of Yilan. (You wouldn’t be able to ride paomagudao in the counter-clockwise approach as you’d be going uphill all the way. Unless you’re Lance Armstrong, I wouldn’t recommend it.) Another advantage to the clockwise route is you don’t need to apply for a mountain entry permit as you’ll be entering the trail from Yilan County, which doesn’t have any police outpost at the trailhead like they do in Wulai. And the biggest advantage to the clockwise route is that you’ll be riding downhill on the sweetest offroad sections of Tonghou. And that’s what made the ride so memorable.
Now the disadvantage to the clockwise route is a steep, long heartbreaking climb from Yilan up to the pass where Tonghou begins. But considering all the pluses, it’s well worth it.
