Hidden along the rocky coast of southern Phu Quoc, there lies a small but extraordinary landmark known as Tien Well (also called Gieng Tien, Gieng Ngu, or Gieng Gia Long). Though nothing more than a shallow pool beside the sea, Tien Well is wrapped in legends, mystery, and the spiritual memory of centuries. This is not only a freshwater source in a place where no freshwater should exist—it is a symbol of hope and survival etched deeply into the cultural history of Phu Quoc.
The Miracle of Tien Well – A Freshwater Source That Never Runs Dry
Located just 2 km from An Thoi town, Tien Well forms from a small underground spring flowing through natural rock. What makes it extraordinary is that no matter how much water is taken, the well never runs dry. Even more miraculous, when the tide rises and seawater reaches the very edge of the pool, the water inside remains clear and sweet, never salty or brackish.
This defiance of natural laws has made local people believe that the well is a blessing from heaven—a sacred gift bestowed upon the island. Many visitors say the water is refreshing, calming, and spiritually purifying. For generations, fishermen have stopped here to wash their face, sip a handful of water, and pray for good fortune before returning to the sea.

The Legend of Emperor Gia Long and the Birth of Tien Well
Tien Well is deeply tied to one of the most well-known legends of Phu Quoc: the journey of Emperor Gia Long (Nguyen Anh) during his flight from the Tay Son forces in the late 18th century. According to folklore, when Nguyen Anh and his soldiers reached the area near today’s An Thoi, they were exhausted, starving, and on the brink of death due to a lack of drinking water.
In despair, Nguyen Anh struck his sword into the rock and prayed:
“If Heaven grants me the throne, then please bless us with fresh water and food.”
Almost immediately, clear freshwater gushed out from the ground, saving his troops. At the same time, schools of anchovies rose from the sea, providing food. Locals believe that this was the moment the anchovy fishery of Phu Quoc—famous today for producing premium fish sauce—was born.
Around Tien Well, people still point out traces believed to be connected to the king: a stone throne, a sword mark, footprints carved naturally into rock, and Ong Doi Cape, named after a loyal general who sacrificed himself to protect the fleeing king.
Tien Well Through Time – A Living Traces of History
Due to centuries of coastal erosion and shifting terrain, Tien Well now lies very close to the shoreline. During monsoon season, waves crash only a few steps away—but the well’s freshwater remains unchanged, adding to its mystery.
The area still retains a rugged, untouched beauty: layers of volcanic rock, windswept landscapes, ancient coastal trees, and the endless sound of waves. Unlike many popular attractions, Tien Well has never been commercialized, making it a quiet and spiritual escape for curious travelers.

Is Tien Well Really Sacred?
For local communities, the answer is undeniably yes. They believe Tien Well brings:
- Health and vitality
- Peace of mind and spiritual clarity
- Good fortune for fishermen and travelers
Visitors often light incense, drink a small amount of water, or wash their face to “receive blessings”. While these beliefs are part of folklore, they contribute to the cultural richness and deep emotional connection locals have with this place.
How to Visit Tien Well in Phu Quoc
Because there is no direct road reaching Tien Well, visitors normally arrive by boat.
Two common routes:
- Hire a motorboat from Bai Khem
- Hire a boat directly from An Thoi pier
Round-trip boat price: 300,000 – 400,000 VND per trip (for 6–8 people).
If you are already visiting the An Thoi archipelago for snorkeling or island-hopping, you can ask the boat operator to stop by Tien Well on the way back.
