The stunning Tò Vò Gate, a natural volcanic arch on Ly Son Island, is a testament to millions of years of geological activity. Formed by ancient volcanic eruptions and sculpted by the relentless ocean, this unique landmark is now at the center of a significant proposal. The People’s Committee of Quang Ngai province has officially submitted a request to the Ministry of Culture, Sports and Tourism to classify Tò Vò Gate as a national monument, recognizing its exceptional beauty and scientific value.
The Ancient Origins of Tò Vò Gate

The Ancient Origins of Tò Vò Gate
The Tò Vò Gate, nestled in Tay An Vinh village, Ly Son district, is a geological masterpiece sculpted by the powerful eruptions of the Gieng Tien volcano millions of years ago. These ancient volcanic events deposited thick layers of basalt rock, which were then subjected to millennia of erosion by the relentless ocean waves. The sea gradually eroded the softer rock in the middle, skillfully carving out the distinctive hollow archway. This unique formation bears a striking resemblance to a wasp’s nest, hence bestowing upon the gate its distinctive name. The geological processes that birthed Tò Vò Gate offer a fascinating glimpse into the island’s dynamic past.
A Natural Wonder’s Unique Features
Measuring approximately 20 meters in length, Tò Vò Gate’s peak rises about 4 meters above the eroded sea surface. At its narrowest point, the arch spans roughly 2 meters, presenting a captivating display of nature’s artistry. Its untamed, distinctive, and singular appearance has cemented its status as one of the most renowned scenic spots in Quang Ngai province and Vietnam. The gate’s allure extends beyond the visible arch, as evidenced by the discovery of another similar volcanic arch offshore of Be Island in 2014. This submerged arch stretches nearly 100 meters, with a 20-meter-long arch roof, further underscoring the region’s profound geological heritage.

Tò Vò Gate’s dimensions offer a glimpse into the scale of nature’s artistry. Stretching approximately 20 meters in length, the arch’s peak ascends 4 meters above the wave-cut platform, showcasing its resilience against the ceaseless marine environment. Its narrowest span, measuring a mere 2 meters, accentuates the arch’s delicate balance and precarious beauty. This unique formation has cemented its place as a celebrated landmark, drawing visitors from across Quang Ngai province and beyond, eager to witness its singular allure.
The discovery of a submerged volcanic arch off Be Island in 2014 adds another layer to the geological narrative. This underwater marvel, extending nearly 100 meters with a 20-meter arch roof, mirrors its terrestrial counterpart, reinforcing the region’s volcanic legacy. The existence of this submerged arch highlights the dynamic geological processes that have shaped the Ly Son archipelago, offering further insights into the island’s formation.
Ly Son Island: A Hub of Volcanic Heritage and Tourism

Ly Son Island: A Hub of Volcanic Heritage and Tourism
Ly Son Island, an idyllic district of Quang Ngai province, is more than just a remote locale; it’s a living museum of volcanic activity and a burgeoning tourist destination. Situated 17 nautical miles offshore, this island district, encompassing Big Island and Small Island, spans roughly 10 square kilometers and supports a community of around 22,000 inhabitants. What sets Ly Son apart is its dramatic geological history, evidenced by the remnants of 10 ancient volcanic craters, three of which are submerged beneath the azure waters.
Beyond its geological significance, Ly Son beckons with pristine beaches and untamed landscapes, offering a unique blend of adventure and tranquility. The island’s allure extends to its culinary offerings, celebrated for fresh seafood and the distinctive Ly Son garlic. Attracting approximately 250,000 tourists annually, Ly Son is a testament to the harmonious coexistence of natural wonders and vibrant local culture, setting the stage for landmarks like Tò Vò Gate to gain national recognition.
The Path to National Recognition

The Path to National Recognition
The formal submission of the proposal on June 27, 2025, marked a pivotal moment in the effort to secure national monument status for Tò Vò Gate. This action followed extensive research and documentation highlighting the gate’s geological importance and cultural significance. The proposal meticulously detailed the formation of the arch, emphasizing its unique volcanic origins and the ongoing impact of marine erosion.
The dossier included comprehensive photographic and cartographic evidence, alongside expert testimonials from geologists and cultural historians. Furthermore, the People’s Committee underscored the potential for sustainable tourism development contingent upon enhanced preservation measures. The national recognition would unlock resources for conservation efforts, including measures to combat erosion and manage visitor impact.
The Ministry of Culture, Sports and Tourism will now undertake a thorough review process, consulting with relevant agencies and experts to assess the merits of the proposal. This evaluation will consider the geological, ecological, and cultural values of Tò Vò Gate, as well as the potential socio-economic benefits of national monument status.
Final thoughts
The proposal to recognize Tò Vò Gate as a national monument underscores its immense value, not just as a tourist attraction but as a significant geological and cultural heritage site. Such recognition would not only boost tourism to Ly Son Island but also ensure the long-term preservation of this extraordinary natural wonder for future generations. It highlights the importance of protecting Vietnam’s unique landscapes and the stories they tell of our planet’s ancient past.
