The unforgettable image of the green Sekau Tunnel is the mangrove forest on both sides extending above the water to form the tunnel. The surface of the standing water reflects the green leaves, creating a dream-like waterway. Because of its dense forests, it has been dubbed the "Little Amazon River". Domestic and international tourists come here to peek into the beautiful tunnel, and bamboo rafts travel up and down the waterway daily. Don't miss the experience of riding on a raft that moves slowly so that sunlight shines through the trees, the sounds of insects and birds surround you and when the boat reaches the end of the tunnel, you will see the remains of the old toll booth. In this quiet, secret part of the city, one can see the beauty of nature in its purest form.
