Wulai is a pretty little town in Taipei county. It's picturesque and famous for its hot springs (they are wonderful!) and its aboriginal history.
Many locals and tourists alike flock to Wulai to bathe in the springs and take a dip in waterfalls which cascade down lush backdrops of mountains. Though many people also come to hike and picnic in the area, the waterfalls are a huge draw.
There also is a gondola available in the area for people to take in the beauty of Wulai's waterfalls from up in the air.
