Bortle 2 · Pristine dark sky ｜ Elevation 3275m ｜ SQM ~21.7 ｜ Best view South
The highest point on Taiwan's road network (3,275 m) and the heart of the Hehuanshan International Dark Sky Park. Thin, clean air and very low light pollution make the overhead Milky Way naked-eye visible — the most accessible high-alpine site on the island.
🌌 Tonight the Milky Way core climbs to a shootable altitude around 20:14, sinks back near 03:04, and peaks around 22:54 at roughly 37° in the South.
Drive-up access via Provincial Highway 14A; observe right by the Wuling car park. Mountain roads are cold and fog-prone at night — dress warm and drive carefully.
Car park and public toilets; no food service — bring your own. Crowded on weekends and meteor-shower nights.
Mar–Oct Milky Way season; the dry autumn/winter is clearer and more stable but colder.
