Sihcao Green Tunnel is right beside and under management of Sihcao Dajhong Temple. There are two raft routes provided, the Sihcao Green Tunnel and Taijiang Boat Ride. Taijiang boat ride takes you out to the shore to explore the coastline of the wetland. The Sihcao Green Tunnel takes you into the canal to examine closely to the plants and the species along the way. The 30 minute raft ride through the well preserved mangrove with greeneries covering the sides and rare species resting randomly in the woods is very relaxing. With a professional guide explaining the history and ecological facts, the ride is also very educational.
Even though the ride through the Sihcao Green Tunnel is only around 30 minutes, but most visitors find it romantic and compelling. It is an interesting experience to raft through a natural green tunnel. And you can always take the other Taijiang Boat ride out to the shores after the canal. The beautiful green tunnel has become more and more popular; it is now one of the most recommended attractions in Tainan.
