得天獨厚的珊瑚礁生態也讓南方四島成為熱門潛水勝地。每年4～9月期間，東嶼坪海域有大片「海底紫色薰衣草森林」，你可以從東嶼坪向下潛，即可看到大片紫色鹿角珊瑚群。
The unique coral reefs also make the four southern islets a popular diving destination.
From April to September, there is a large “underwater purple lavender forest” in the waters of Dongyuping, from which you can dive down to see large fields of purple staghorn corals.
然而，前往一探秘境前務必注意，潛水時切勿碰觸、避免蛙鞋踢到珊瑚。
Be careful not to touch or kick the coral while diving, however, as the sea living creature is extremely fragile.
