Located near Sanfu Port in western Liuqiu, Sanfu Ecological Path has a uniquely eroded coastal landform with a variety of features such as column-shaped coral formations similar to Vase Rock, small caves and potholes. The column-shaped coral formation looks like a mushroom because its lower part becomes thinner, like Vase Rock, as a result of being eroded by the sea over a long period of time.

The potholes on the eroded platform are formed by being continuously eroded by the waves and salt, so you can see salt crystals around some of them.

In comparison with other scenic spots on the island, Sanfu Ecological Path is richer in geological sights, especially the potholes which can be seen only here.
