Beihai Tunnel (Nangan)
北海坑道
A huge waterway tunnel carved by hand into granite, able to hold more than a hundred small boats. During the blue tears season, visitors can row into the tunnel at night.
The Beihai Tunnel on Nangan is in Ren'ai Village. Soldiers began excavating it by hand and with explosives in 1968. The main waterway is about 700 meters long and about 18 meters high, and it can hold over a hundred landing boats. It is the most impressive wartime engineering project in Matsu. Visitors can walk along the path at low tide, while water levels rise at high tide. During the blue tears season, there are night rowing experiences, which must be booked in advance. The tunnel is generally open from 8 a.m. to 5 p.m. and admission is free. The floor is slippery, so be careful when going inside. It can be combined with Dahan Fort and Iron Fort for a half-day route.
