Ride southward along the coastline from the sailstone to the sand island. Sand island is the beach with the highest content of shell sand, reaching 97.7 (%). Although beaches and coastlines can be found everywhere in Kenting, the sand islands are quite special, and the shellfish sand content is very high, which is well protected. There is a shellfish sand exhibition hall beside the sand island, which shows the content of shellfish sand in various beaches of Kenting and the history of shellfish sand formation. It is worth visiting. We should cherish the gifts of nature and treat these natural beauty kindly.
