Sicao Green Tunnel refers to the mangrove area in the water channel behind Sicao Dazhong Temple. Native mangrove trees that are over fifty years old grow densely on both banks of the channel, forming a natural tunnel-like waterway. It’s the only green tunnel on the water in Taiwan, and is also known as "Mini Amazonia.”
