Discover the mystical Dau Go Cave in the heart of Ha Long Bay

1 An overview of Dau Go Cave

Dau Go Cave is one of the most magnificent limestone caves in Ha Long Bay, often likened to a "wonder within a wonder." Located about 3km from Tuan Chau Island and 6km from the Bai Chay tourist area, this place captivates visitors with its pristine and mystical beauty. The diverse shapes of stalagmites and stalactites inside the cave create a setting akin to a natural palace nestled deep inside the rocky mountain.

Perched at an elevation of 27m above sea level, the cave covers an area of nearly 5,000m², with an entrance 17m wide and 12m high opening into a splendid interior. According to geologists, Dau Go Cave was formed approximately 2 million years ago, around the same geological era as Thien Cung Cave, located just a few hundred meters away.

Beyond its imposing structure, Dau Go Cave in Quang Ninh also stands out for its rich flora and fauna ecosystem, offering an ambiance that is both majestic and full of life.

2 Legends behind the origin of Dau Go Cave in Quang Ninh

Right from its name, Dau Go Cave evokes a sense of mystery among visitors. Over the centuries, that name has been passed down by local bay residents through various stories, each steeped in legendary allure.

According to the first legend, the cave is associated with the glorious exploits of General Tran Hung Dao during the resistance against the Mongol-Yuan invaders in the 13th century. Legend has it that he ordered troops to plant large wooden stakes to thwart enemy warships, contributing to the resounding Bach Dang victory. After the battle, numerous wooden pieces remained scattered inside the cave, prompting locals to call it Giấu Gỗ Cave (Hidden Wood Cave), which was later corrupted over time into Dau Go.

The second legend has a more everyday connection. In front of the cave entrance lies an arc-shaped chain of islands creating a wind-sheltered inlet where fishermen could anchor and take refuge during storms. While staying there, they often repaired and built boats, leaving behind numerous pieces of wood scattered around the area. From then on, the name Dau Go was coined, serving as a rustic reminder of a working life at sea.

According to the third legend, bay locals recount that viewed from afar, Dau Go Island resembles a massive log with two circular holes drilled into either end as if meant for threading ropes. That peculiar shape led people to name the spot Dau Go (Wooden Log), a name that is both straightforward and evocative.

Though no one knows the exact origin of this name, it is perhaps these oral legends that have shrouded Dau Go Cave in a mystical haze, making it all the more captivating to travelers.

Notably, in 1938, the renowned French travel magazine Merveille de Monde published an article praising the cavern and dubbing it the "Grotte des Merveilles," meaning the Cave of Wonders. This title serves as an eloquent testament to the extraordinary, rare beauty of Dau Go Cave.
