When you set sail on a Halong Bay day cruise, the stunning limestone karsts and emerald waters are just the beginning. Beneath this natural wonder lies a world of ancient legends — stories of dragons, warriors, celestial weddings, and mystical guardians passed down through generations.
If you’re planning to visit Halong Bay, these myths aren’t just folklore — they’re woven into the very landscapes you’ll see from your boat. In this article, we explore the top mythical stories that shape the identity of Halong Bay and show you where to experience them during your cruise.
Why Halong Bay Is More Than Just a Scenic Cruise

While Halong Bay’s beauty is undeniable, its cultural and mythological richness offers deeper meaning to each rocky island and cave. These stories:
-
Give symbolic life to natural landmarks
-
Connect travelers with Vietnam’s ancient past
-
Make every stop on your cruise feel magical
Many Halong Bay day cruises now incorporate storytelling or guided narratives to bring these legends alive for visitors.
The Origin Legend: Where Dragons Descended
The name “Hạ Long” means “Descending Dragon”, and its origin lies in the most famous legend of the bay.
The Story of the Mother Dragon and Her Children
Long ago, when Vietnam was being invaded, the Jade Emperor sent a family of dragons from heaven to help protect the land. The Mother Dragon and her children descended upon the bay and spat jewels and jade into the sea. These transformed into the thousands of limestone islands that blocked enemy ships and brought peace to the land.
After the battle, the dragons chose to stay, giving the bay its name: Ha Long Bay — the place where the dragon descended.
Where to Experience This: You’ll pass through these “dragon-made” formations during any standard cruise route, especially around Dinh Huong and Ga Choi Islets.
The Fighting Cock Islets (Hòn Gà Chọi)

You’ll likely recognize these twin rocks — one taller, one shorter — that appear to be sparring in the water. They’ve become the iconic symbol of Halong Bay, printed on postcards, travel brochures, and even Vietnamese currency.
The Tale of Eternal Love and Loyalty
According to legend, these are two fighting roosters sent to guard the bay. Over time, they turned to stone — frozen in their final duel, forever watching over the sea. Others believe they represent a pair of lovers, loyal even through time and tides.
Photography Tip: You’ll see them on most routes within the first hour of cruising from Tuan Chau or Bai Chay Port — cameras ready!
Dau Go Cave (Wooden Stakes Cave)
Dau Go Cave may sound poetic, but its story is rooted in military legend.

The Legend of the Hidden Stakes
In the 13th century, Vietnamese hero Trần Hưng Đạo used wooden stakes planted underwater to defeat invading Mongol forces. He hid these stakes in this very cave. When the tide lowered, the stakes impaled enemy ships, securing a famous victory.
Today, the cave is named “Dau Go” — which translates to “Cave of Wooden Stakes.” You can still see wooden-like rock formations as you explore its chambers.
How to Visit: Included in some longer day cruises and overnight itineraries. Ask for a cultural or historical cruise package.
Thien Cung Cave: The Heavenly Palace

Not all Halong Bay legends are about war — some are filled with fantasy and love.
The Royal Wedding in the Sky
Thien Cung Cave tells the tale of a Dragon Prince who married a mortal girl. Their heavenly wedding took place in this cave, lit by celestial lights and filled with music and dance. The swirling rock formations inside resemble dragons, phoenixes, and dancers, said to be the remnants of the celebration.
Today, the cave is known as “Heavenly Palace Cave” and is one of the most popular stops on luxury and mid-range day cruises.
Other Hidden Legends of the Bay
The Fairy Lake of Bo Hon Island
Tucked within the cliffs is a natural pool known as the Fairy Lake, where fairies would bathe under the moonlight. The secluded feel of the spot gives it an almost ethereal vibe.

Bai Tu Long Bay: The Baby Dragon
According to some variations of the original legend, the Baby Dragon landed nearby and created Bai Tu Long Bay. It’s considered the “younger sibling” of Halong Bay and is part of many off-the-beaten-path cruise routes.
Where These Stories Come Alive on a Halong Bay Day Cruise
Not every cruise is the same. If you want to experience the mythical side of Halong Bay:
-
Choose cruises that include Thien Cung Cave or Dau Go Cave

-
Visit during winter or foggy season (Dec–Feb) for a mystical, “legendary” atmosphere.
