Hard to escape summertime daytime heat in Taiwan even in mountains. People that can just stay indoors.
Mountains towns will be slow, sleep at dark, maybe a chain convenience store, maybe just grandpa shop.
Maybe
- Alishan, 2500m, nothing
- Chingjing, 1700m, dull
- Duona 多納, 1500m, nothing, aboriginal
- 奮起湖 Fengqihu, 1400m, tourists on weekends and train station
- Lalashan, 拉拉山, 2000m, nothing
- Lishan, 2000m, nothing
- Puli, dull
- Ruili, flat area in the mountains,
- 日月潭, Sun Moon Lake
- Wutai, 1000m, aboriginal
No place, no mountain, no beach, in Taiwan is easy to escape summertime heat. Good idea to find places that you like and make the best of it.
