Thoi Loi Mountain is one of the most prominent landmarks on Ly Son Island, Quang Ngai Province. Rising approximately 169 meters above sea level, it is the island’s highest point, offering visitors panoramic views of the sea, sky, villages, and Ly Son’s signature shallot and garlic fields. Beyond its scenic beauty, Thoi Loi serves as a significant geological feature, bearing witness to the island’s volcanic origins.
Overview of Thoi Loi Mountain
Thoi Loi (Vietnamese: Thới Lới) was once a volcanic crater that has long been dormant. Millions of years of geological formation, weathering, and erosion have sculpted the area into towering cliffs and distinctive layers of volcanic rock. On one side, near-vertical cliffs face the sea, creating a dramatic and majestic landscape. A freshwater reservoir now sits atop the crater, supplying water for both daily life and agriculture on the island.

The mountain’s greatest draw is the expansive view from its summit. From the top, visitors can look down upon the patchwork of shallot and garlic fields interspersed with residential areas and the clear blue coastline. On clear days, the blue of the sea blends with the sky to create a vast, open vista, perfect for sightseeing and photography.
The mountain is also home to the Vietnamese Flagpole, a striking landmark facing the sea. It serves as both a tourist attraction and a symbol of national sovereignty over the islands. Access to Thoi Loi is relatively convenient; visitors can travel by motorbike or car to a point near the summit.

The best times to explore Thoi Loi are early morning or late afternoon, when the weather is cool and the sunlight is not too harsh.

With its unique volcanic landscape, panoramic views, and vast expanse of sea and sky, Thoi Loi Mountain is considered one of the most scenic spots on Ly Son Island. It is an ideal destination for visitors to explore nature and learn about geology while fully appreciating the distinctive beauty of this volcanic island set amidst the ocean.
