Da Bia Mountain: The Majestic "Thach Bi Son" in the New Dak Lak

Crossing the winding roads of Deo Ca Pass, the eyes of any traveler will be drawn to a colossal rock mass soaring into the clear blue sky. That is Da Bia Mountain – a heritage entity that embodies both the soul of the sea and the spirit of the mountains. From July 1, 2025, when the new era from Resolution 202/2025/QH15 officially comes into effect, this legendary mountain of the former Phu Yen Province will become the "coastal rooftop" of the new Dak Lak Province. This transformation not only changes the administrative name but also opens a new chapter for connecting Vietnam's historical values from the highlands to the East Sea.

Thach Bi Son: A Unique Historical and Geological Formation

From Local Trips' expert perspective, Da Bia Mountain is not merely a mountain, but a "historical witness" carved from Granite over millions of years.

Border Marker of King Le Thanh Tong

The most important feature that made this mountain famous is the colossal rock mass on its peak. According to historical records, in 1471, during his southern expansion campaign, King Le Thanh Tong had characters carved into this rock to mark the sovereignty and delineate the border between Dai Viet and Champa. Although time and weathering have faded the ancient inscriptions, the spirit of the "Heavenly Stele" still endures as a symbol of national pride.

A Masterpiece of Mountain Formation

Geologically, Da Bia Mountain is a rare Granite monolith. Formed from the eruption and intrusion of magma, then weathered by wind and sea rain over millions of years, this rock mass now has a magnificent shape, changing with each viewing angle: sometimes resembling a majestic general, sometimes a lion guarding the bay.

List of Administrative Units and Nearby Connections

The journey to conquer Da Bia Mountain will be complete when you connect with the closely linked entities in the heritage system of the former Phu Yen province:

1. Vung Ro Bay: Located right at the foot of the mountain, preserving the legends of the No-Number ships and pristine blue beaches.
2. Mui Dien (Dai Lanh Cape): The first place to catch the sunrise on the Vietnamese mainland, only about 10km from the foot of Da Bia Mountain.
3. Deo Ca Tunnel: A modern transportation infrastructure connecting trade between the new Dak Lak and Khanh Hoa, making travel safer and more convenient.

Taste Map: The Intersection of Seafood and Forest Delicacies

Conquering Da Bia Peak consumes a lot of energy, and this is when you need to enjoy the culinary quintessence prepared by the local people:

Tourism Economy and Sustainable Development Orientation

Since its merger into the new Dak Lak Province, Da Bia Mountain has been oriented to become a focal point for forest-sea eco-tourism. The application of digital transformation in tourism allows tourists to scan QR codes along the trekking route to learn about the plant ecosystem and the history of Thach Bi Son.

The new provincial government is promoting the conservation of Deo Ca special-use forest, limiting negative impacts on the natural environment. The development of professional trekking routes is creating more jobs for local people, while also boosting the night economy in Tuy Hoa City as tourists return to rest after their journey to conquer the peak.
