This article provides essential insights into Kim Quy Cave, covering its location, origins, structure, and the myriad sights and experiences awaiting you. Join us as we explore Kim Quy Cave—a legendary marvel of Halong Bay!
Location and History of Kim Quy Cave
Kim Quy Cave is nestled on Dam Nam Islet within Halong Bay, Quang Ninh Province. Situated at an altitude of 187 meters above sea level, the cave is flanked by Dam Bac Islet to the front and Soi Sim Islet to the rear. Spanning 100 meters in length and ranging from 5 to 10 meters in width, it stretches longitudinally from north to south. The cave was naturally sculpted over millions of years through marine erosion against the limestone mountains.

Kim Quy Cave is also known as Golden Tortoise Cave because it houses a distinctive rock formation resembling a sleeping tortoise. According to legend, this rock represents the Golden Tortoise—a divine spirit that aided King Le Loi in defeating the Mongol-Nguyen invaders before retrieving its sacred sword and returning to the sea. Upon arriving in Halong Bay, the Golden Tortoise sought permission from the Dragon King (Water God) to remain and eradicate the malevolent spirits plaguing the locals. Having successfully completed its mission, the Golden Tortoise sought out this tranquil cavern to rest and petrify into stone.
Beyond its rich historical lore, Kim Quy Cave allures visitors with its staggering natural splendor. The cavern is adorned with pristine, ivory-white stalactites cascading gracefully from the ceiling. These mineral formations take on extraordinary shapes, resembling ancient trees, dragons, or majestic horses. Furthermore, the cave features crystal-clear subterranean pools whose gentle waters ripple throughout the year. Visitors can also admire the exquisite strata lines—masterpieces meticulously crafted by nature upon the stone walls. Notably, the cave features a vivid recreation of the historic Bach Dang battleground, a monumental milestone in Vietnamese history. Here, one can observe over thirty ironwood stakes that were commanded by Hung Dao Dai Vuong to be driven into the Bach Dang River to repel the Mongol-Nguyen invaders.
Structure of Kim Quy Cave
To enter Kim Quy Cave, guests navigate a narrow entrance just one meter wide, discreetly concealed among towering limestone boulders to create an aura of mystery and allure. Upon stepping inside, travelers are immediately embraced by the cool, refreshing atmosphere of the cavern. Natural daylight and thoughtfully placed lighting blend to cast a shimmering, ethereal glow throughout the interior, making one feel as though they have wandered into an enchanting, otherworldly realm of wonder.
Kim Quy Cave comprises three main chambers: the outer chamber, the middle chamber, and the innermost chamber. Each section possesses its own distinct and captivating characteristics:
- The Outer Chamber: A mesmerizing space where pristine, ivory-white stalactites drape softly from the cavern ceiling. These formations evoke whimsical imagery—reminiscent of ancient trees, mythical dragons, or charging horses—allowing visitors to easily conjure up fairy tales and folklore. This chamber also houses the iconic tortoise-shaped boulder, believed to be the petrified remains of the Golden Tortoise after aiding King Le Loi.
- The Middle Chamber: Characterized by pristine, crystal-clear water pools that murmur softly year-round. Here, guests can marvel at the magnificent mineral veins bestowed by nature. These striking grey-and-white striped patterns on the limestone layers formed over millions of years through the decomposition of marine organisms, lending the cave a vibrant and richly textured aesthetic.
- The Innermost Chamber: A chamber that vividly recreates the historic Bach Dang stake battlefield. Visitors will discover over thirty ironwood-like formations reminiscent of the stakes deployed by Grand Commander Tran Hung Dao along the Bach Dang River. In reality, these structures are exceptionally durable and resilient stalagmites. Not only do they imbue the cave with a heroic and majestic ambiance, but they also serve as enduring symbols of Vietnamese patriotism and unwavering resilience.
