The Sicao Green Tunnel (四草綠色隧道), known as the ""Amazon River of Taiwan,"" is a must-visit attraction in Tainan. The highlight of this place is taking a bamboo raft to cruise through the green tunnel, which takes about 30 minutes. Each boat can accommodate around 50 people and travels to the deepest part of the tunnel, where the mangrove forest on both sides becomes even denser, creating a tropical rainforest-like experience.

During the boat ride, there are tour guides who provide explanations about the mangrove ecology along the way. The guides are very professional and use lively language to deepen our understanding of the mangroves. In the summer, there's no need to worry about getting sunburned, as sun hats are provided on-site. Next to the starting point of the boat ride is the Sicao Temple, and nearby, there is a small Bryde's Whale Museum where visitors can enter for free with their ticket stubs to see the specimens of stranded Bryde's whales and their calves.

It is recommended to purchase tickets online and then scan the QR code at the right side entrance of the temple on the day of the visit for convenient self-ticket retrieval.
