[Taiwan] 馬祖，南竿島，北海坑道

北海坑道，由於它的壯麗，成為了南竿島上必去的景點。
The Beihai Tunnel might be the most famous tunnel at Nangan. 

由於它的特殊性，偶爾還是要有運氣才能走路參觀的，若遇到漲潮，人行道是會被淹沒的。
To visit here, you may need to check the tide first. It will be closed at the high tide.

懶惰一點，可以搭船遊一圈，或者走路，大約可以慢慢逛個二三十分鐘，不過我建議用走的，因為晚上應該會再回來尋找藍眼淚，到時候，就一定要搭船了。
If you're lazy to walk through, you can take a boat. In fact, you may come back at night, there are tours for finding sea sparkle here, you will need to take the boat.

在隧道裡走一圈，真心覺得是鬼斧神工，壯觀！
The tunnel is huge and amazing.

晚上回來尋找藍眼淚，這兒的確一定會有藍眼淚，也幸好有這個經驗，稍後成功地找到了野生的藍眼淚！
We came back at night for the sea sparkle. And you will see it here always.
