When you are arriving in Kinmen with a plane, the first thing that you see is this long bridge from your window seat! That's how we saw it during our visit!. It is a 5-kilometer-long bridge connecting Greater Kinmen Island and Lieyu Island in Taiwan.
From there you can get a glimpse of Xiamen, China, which is very cool! Especially during sunset and night time when the lights became very beautiful on the bridge. Recommend watching sunsets there!
