In my opinion, the Taroko Cross-Island Highway is a more challenging road than the Su'ao-Hualien Highway, but the experience is great. The most enjoyable part of my 8-day trip in Taiwan was the mountain road to Hehuanshan, followed by the Cross-Island Highway.

The day I drove was not a weekend, so there were few cars on the road, which was good. There were many turns on the single-lane road, so you had to drive carefully. The drivers in Taiwan drive fast, so I always drove at the limit. The passengers were easy to get carsick. There were just too many turns.

For people with experience on the mountain road, it's not a big problem, but be sure to pass in the morning, in the afternoon there is dense fog, afraid it's not safe, the speed can only be around 40, so it's also quite tiring.

I am in Taipei now, and last year I crossed the Central Cross-Island Highway, and it was at night! It will be unforgettable in this lifetime, not because of the beautiful scenery, but because it was so thrilling! It's not just the winding road, that's just the surface! The most exciting part is the high altitude and frequent heavy fog, the kind of fog where you can't see even 5 meters ahead! This time from Sun Moon Lake to Alishan, I encountered the same situation, so I can conclude: this route is not only an exciting experience, but also thrilling! It's rare to see such beautiful scenery!
