Taipei's basin setting traps humidity and light pollution (Bortle 7–8), but Taiwan's mountainous spine provides quick escapes — Hehuanshan (Hehuan Mountain) at 3,275m is one of Asia's most accessible high-altitude observing sites, reachable by road. Taiwan's subtropical climate means summer thunderstorms are frequent, but autumn and winter bring clearer conditions. The east coast has less light pollution than the western plain. Kenting National Park in the south offers Bortle 3–4 conditions.
