Sicao Green Tunnel(四草綠隧)

Traveler rating:4 230 Reviews

Thursday:08:00 – 16:00





The most memorable image of Sicao Green Tunnel (四草綠隧) is the mangrove forest on either side extending over the water to form a tunnel. The still surface of the water reflects the green leaves, creating a dream-like fantasy waterway, and because of its dense forest it has been given the nickname "Little Amazon River". Domestic and international tourists come here to glimpse the beautiful tunnel, and bamboo rafts travel up and down the waterway daily. Riding on a slowly moving raft, sunshine glints through the trees, the sounds of insects and birds surround you, fiddler crabs wave at you from the water's edge, and mudskippers emerge to look at you with their enormous eyes. When the boat reaches the end of the tunnel, you will see the remains of the old toll booth, before reluctantly drifting back the way you came. In this tranquil, secret part of the city, one can see nature co-existing with the city in harmony.

    Good experience

    Traveler rating:4 2019-10

    The boat ride is 30 minutes. The tunnel formed by the mangroves is beautiful. There are many smalls crabs by the banks as well. The water is clear, but according to the guide, the water is usually murky in summer when there is a lot of rain. Recommended to visit in the morning when it is not so hot. The boat will depart once there are 50 passengers to fill it up. There will be a fixed time which the boat will depart if there are less than 50 passengers.

    I would not have guven this the one dot rating but had to in order to post review. This is a very very short boat ride, approx 10 minutes. You'll stand in line longer and it's Mandarin only. The mangroves are not that special, the tunnel refers to the trees that overhang which is only a brief part of the brief ride. The bus ride to get there was 1 hour. Not worth the almost $7 US price. Go to the tree house in Tainan instead.

    Best boat experience to see a mangrove swamp

    Traveler rating:5 2018-12

    You will need to buy a ticket to take a raft ride into a mangrove swamp. The whole ride is 30 minutes. In the swamp, you will see four kinds of mangrove found in Taiwan and wildlife on both sides of the waterway. The water is very clean and clear, as it is only about 1 meter deep. The highlight is a natural tunnel formed by the trees. The scenery and landscape is spectacular. It gives you a great feeling that you are going through the forest of the Amazon river. Do plan to go there in the morning, otherwise it is very hot and the raft is open air.

    You would only need 1 hour here

    Traveler rating:3 2018-11

    In summary, its a slow, simple and quaint raft ride down a narrow river/canal with mangrove plants and small crabs at the side. The ride that I took was half hour long, with waiting time another half hour. There is a longer ride available but i didnt opt for it. It isn't that much of a wildlife experience I imagined to be honest.
