Located in Tay Village, An Vinh Commune on Ly Son Island (Quang Ngai Province), Cổng Tò Vò is one of Vietnam’s most iconic natural landmarks. This striking basalt arch, formed entirely by nature, rises proudly on the edge of the sea and has become a symbol of Ly Son’s wild beauty.
With its unique silhouette resembling a “stone gate” opening toward the East Sea, Cổng Tò Vò is a must-visit destination for anyone setting foot on Ly Son Island.
A Natural Basalt Arch Sculpted by Ancient Volcanoes
Cổng Tò Vò is a natural basalt arch measuring nearly 8 meters long and 5–6 meters high depending on the tide. It was formed thousands of years ago from the eruption of the Gieng Tien volcano, which created thick layers of basalt along the shoreline.
Over time, coastal erosion and the Flandrian transgression gradually carved away the softer rock in the center, leaving behind the solid upper structure. This natural sculpting process created an extraordinary arch that resembles the nest of a “tò vò” (a type of mud wasp), giving the landmark its name.
This rare geological formation is considered one of the most unique volcanic relics in Vietnam—a true masterpiece shaped by nature.

Officially Recognized as a National Scenic Monument
On September 9, Vietnam’s Ministry of Culture, Sports and Tourism officially designated Cổng Tò Vò as a National Scenic Monument.
The recognition affirms the site’s outstanding values:
