2. Legend of Kim Giao Forest
Amidst the wild beauty of Cat Ba National Park, Kim Giao Forest is not only a natural wonder but also a land associated with legends and love. According to local legend, the name “Kim Giao” originates from the tragic but immortal love story between Princess Kim Ngan, a beautiful woman, and General Ngoc Giao, a talented and kind warrior. Because they were prevented from being together, the lovers chose to transform into forest trees so that their souls could be together forever. Since then, the forest has been called Kim Giao, a symbol of faithful and immortal love, passed down through generations of Cat Ba people. More than just a legend, the Kim Giao tree holds a special place in Vietnamese history. Its wood was once used to make chopsticks for kings, as ancient people believed it had the ability to detect poison changing color or showing unusual signs when exposed to toxins. This belief has turned the Kim Giao forest into a sacred space, where nature, culture and tradition intersect
Today, as you walk beneath the emerald green canopy, you can almost hear the whispers of fairy tales carried by the wind. The legend of Kim Ngan and Ngoc Giao has breathed life into Kim Giao Forest transforming it from a simple trekking trail into a vivid story of love, heritage and harmony with nature.
For those seeking more than a beach holiday, this mystical forest offers a deeper connection to the cultural and ecological richness of Cat Ba Island.
