Getting There & Around
How to Get to Nan-an Falls
The falls sit in Taiwan’s eastern highlands; access is usually by car or scooter from the nearest county town. Expect narrow, winding roads and short walking approaches from roadside parking. Public transit is limited-take the regional bus to the nearest village and ask locally for directions or a short taxi from the stop.
Tips for Visiting Nan-an Falls
- Visit early morning when mist hangs in the gorge and light catches the falls' spray-fewer people and better photos.
- Wear sturdy shoes: wet rocks and a short scramble are often required to get a close view.
- Bring a waterproof layer; spray from the falls can chill even in warm weather.
