Islet Trung, also known as Hon Phu Tho or Hon Da Bac, is a small islet whose shape resembles a giant white egg—covered entirely in a layer of bird droppings, giving it a striking pale color. It is one of the major seabird nesting grounds in southern Vietnam, with a total area of 0.100 km².
From a distance, the island looks like a hippopotamus quietly soaking in the sea. As you circle around by boat, the islet reveals two distinct sections: a smaller rocky peak with a vertical stone pillar, and a larger rocky mass covered with sparse vegetation. Its cliffs are smooth and slightly slanted, while several massive boulders rest precariously at the summit, leaning toward the ocean as if ready to fall.
Hon Trung Lon is completely uninhabited. Its vegetation consists mainly of wild pineapple, Morinda trees, various climbing vines, and hardy coastal grasses—plants well adapted to the harsh, windswept environment of Con Dao’s outer islands.
