Lý Sơn Island in Vietnam Gains Spotlight as ‘Jeju of Vietnam’ for Volcanic Landscape and Tourism Growth

Lý Sơn island, a district of Quảng Ngãi province located about 30 km northeast of the mainland, covers just over 10 km² but is renowned for its ancient volcanic formations. Geological studies show the island was created by eruptions 25‑30 million years ago, leaving basalt layers, lava pillars and a large crater lake at Mount Thới Lới, the highest peak at roughly 170 m.

Key attractions include the 350 m‑wide crater lake, the well‑preserved Giếng Tiền volcanic vent, Hang Câu cave with striking basalt walls, and the natural stone arch at Cổng Tò Vò. The island’s landscape has earned it the nickname “Jeju of Vietnam” and led to its designation as a national historic‑geological site.

Archaeological evidence traces human occupation back 2,500‑3,000 years, with Sa Huỳnh and Cham cultural influences before Vietnamese settlement in the 16th‑17th centuries. The local population is noted for its garlic production and a historic link to the Hải đội Hoàng Sa naval unit that once patrolled the surrounding seas.

Tourism data released by Agoda show a sharp rise in search interest for Lý Sơn in early 2026, indicating growing domestic and international visitor numbers driven by its unique geology and cultural heritage.
