When to Visit Alishan: Cherry Blossom, Clouds and Cold
The seasons on the mountain — from the mid-March cherry peak to the clear autumn mornings that give the best sunrise odds.

Alishan's most celebrated season is the cherry blossom, and for good reason: the mountain holds Taiwan's largest concentration of Yoshino cherry, roughly 18,000 trees, which turn the forest pink each spring. The 2026 season opened around 10 March, with the Yoshino peak in mid-to-late March and later varieties carrying the display into early April; the festival runs to about 10 April. It is glorious and hugely popular — around 150,000 visitors pass through, trains and lodging fill up, and you'll need to book well ahead. Come for the blossom knowing you're sharing it.
Autumn: the best all-round window
For many visitors, October and November are the sweet spot. The falling temperatures and clear autumn air give the best odds of both a clean sunrise and a dramatic sea of clouds, the crowds are thinner than in cherry season, and the forests take on gold and red tones. If your priority is the classic Alishan spectacle — sun over Jade Mountain, cloud filling the valleys — autumn is the season to aim for.
Winter: crisp cloud-seas
Clear winter mornings, from December into February, can produce the crispest seas of cloud of all, with cold, still air and sharp light. The trade-off is the cold: the sunrise platform can be genuinely freezing, so serious layers are essential. But for a still, clear winter dawn above the clouds, with fewer people around, some seasoned visitors rate winter the finest time of all.
Summer: cool escape, more mist
Summer turns Alishan into a cool refuge from the lowland heat — welcome when Taiwan's cities are sweltering — but it's also the mistiest and wettest season, with frequent afternoon cloud and rain, and the July–September typhoon season can disrupt the railway and roads. It's still a lovely time to walk the forest, but the odds on a clear sunrise are lower, so come for the trees and the cool air rather than banking on the dawn.
Whatever the season, dress warm
One rule holds all year: pack warm layers. Alishan sits about ten degrees cooler than the lowlands, and the pre-dawn viewpoints can approach freezing even in summer. A proper jacket, a warm layer underneath and good shoes for the damp boardwalks will make any season on the mountain far more comfortable — and the difference between enduring the sunrise wait and enjoying it.
