Magang Observatory, located at 107.7K of Provincial Highway 2, boasts impeccable coastal scenery. It is ideal for exploring geological formations, intertidal zones, and a seamless sky-and-sea. This is even a good place to rest if you take a circular bicycle trip of Old Caoling – there are toilets to use and beautiful oceans to watch. The intertidal zone below the observatory has the most populated green algae in Taiwan, and thus its ecology is highly diverse. All year round, visitors can find a wide range of intertidal-zone creatures.
