I started this walk from Siaogang KMRT station. The coastal route would have led through restricted-access port facilities, so I hoofed it from Siogang station to Kaohsiung harbor, a journey of a couple of hours, and finally got to see the sea again. I was pretty impressed with the harbor. I love harbors and ships, and this one was world class.
Cijing island is an interesting place. It's a long, thin island, roughly 10 km in length and one in width, that forms a natural barrier protecting Kaohsiung's harbor. In fact, it is one of the reason why Kaohsiung has a great harbor, as Cijin shelters it from wind and wave, including fierce seasonal typhoons.
Because of its position, it has a dual nature: the western side is open to the ocean and is fresh and natural; the eastern side faces the harbor and is more gritty and polluted.
