The Sicao Green Tunnel is a short boat ride through mangroves in Tainan's Annan District, where branches lean over the water to form a natural canopy. The attraction is simple but memorable: slow water, reflections, birds, and green shade close to the coast.
It pairs well with the wider Taijiang wetland area and Anping's historic sights. The ride is popular and can feel busy, but it gives urban Tainan a clear link to the marshes, salt fields, and coastal ecology that shaped the old lagoon landscape.
