The Legend of Trinh Nu cave
Local tradition tells a heartbreaking story of a beautiful girl who refused an arranged marriage by a wealthy mandarin, as she was already engaged to a poor fisherman.
Enraged by her refusal, the mandarin exiled her to this remote island. Exhausted and heartbroken, the girl eventually turned to stone while waiting for her lover to return from the sea. Today, the central stalactite of Trinh Nu cave strikingly resembles a woman with long flowing hair looking desperately out toward the horizon.
Fun Fact: The fisherman, caught in a storm while searching for her, also turned to stone on a nearby island, which is now known as Trong Cave (Drum Cave). This story of unwavering loyalty has made the Virgin Cave a sacred spot for locals and romantic travelers alike.
How to Get to Virgin Cave
Reaching this offshore monument requires a coordinated journey by water, as no land-based infrastructure connects the island to the mainland.
- Public Sightseeing Boat (Route 2): To visit this spot independently, you must purchase a Halong Bay Route 2 sightseeing ticket (approx. 290,000 VND/person, plus boat rental fees). Boats depart daily from Tuan Chau Marina or Halong International Cruise Port. The full Route 2 journey typically takes 5.5 to 6 hours, making stops at Sung Sot Cave, Ti Top Island, and Trinh Nu Cave.
- Private Canoe or Speedboat: For those seeking efficiency and a customized schedule, renting a private high-speed canoe is a premier choice. This method allows for a quick 15-minute transit from the harbor and provides more time for photography at Trinh Nu cave without the pressure of a large group schedule.

Best Things to Do at Trinh Nu cave
The environment surrounding the cave offers a variety of experiences that blend physical exploration with emotional storytelling.
Explore the Cave Interior and Rock Formations
Venturing into the chambers of Trinh Nu cave reveals a complex system of stalactites and stalagmites sculpted over millions of years. The interior is divided into several sections, with narrow passages opening into wider halls where the ceiling is decorated with intricate mineral ripples. Observation of the play between natural light and shadows on the limestone walls provides a fascinating look at the geological evolution of the Virgin Cave.
Relax on the Quiet Trinh Nu Beach
Located at the mouth of the cave is a small, pristine stretch of white sand known as Trinh Nu Beach. This area is exceptionally quiet, as it is shielded from the main boat traffic by high karst walls, providing a peaceful environment for a short rest. The emerald water here is calm and shallow, offering a perfect opportunity for a refreshing dip or a mindful walk along the water’s edge near Trinh Nu cave.
Take Photos with the Virgin Stone Statue
Capturing a photograph of the stalactite that serves as the namesake for the cave is a top priority. This natural sculpture, found deep within the first chamber, possesses a lifelike silhouette of a woman looking out to sea. Finding the correct angle to highlight the “flowing hair” of the stone figure is a highlight for photography enthusiasts visiting Trinh Nu cave.
Listen to the Legendary Love Story
Engaging with professional narration of the local folklore adds a layer of spiritual depth to the visit. The story is often shared while looking out toward Trong Cave, where the lover is said to have also turned to stone. This auditory experience transforms the Virgin Cave from a geological site into a living monument of Vietnamese folk culture and eternal devotion.

Nearby Attractions Trinh Nu cave in Halong Bay
The central position of Trinh Nu cave allows for an efficient Route 2 itinerary, covering several world-class landmarks in a single journey:
Trong Cave (Drum Cave)
Located directly opposite Trinh Nu cave, this is the “male” counterpart in the famous romantic legend. The cave is famous for the natural drumming sound produced when wind echoes through its twin arched entrances. It serves as a majestic architectural twin to the Virgin Cave, and most boats stop at both locations to complete the legendary story for guests.
Sung Sot Cave (Surprise Cave)
Situated nearby on the same Bo Hon Island, this is the largest cavern in the bay, featuring massive chambers that resemble a natural limestone cathedral. The interior is brilliantly illuminated to highlight thousands of intricate stalactites and stalagmites that have formed over millions of years. A visit here provides a grand subterranean contrast to the quiet and poetic atmosphere found at Trinh Nu cave.
Luon Cave
Luon Cave is a natural tunnel archway that leads into a tranquil, enclosed lagoon surrounded by sheer vertical cliffs. It is considered the premier location in the bay for kayaking or taking a traditional bamboo boat ride to experience the scenery from water level. The high cliffs protecting the lagoon are often inhabited by wild golden monkeys, adding a touch of wildlife observation to the Trinh Nu cave itinerary.
Ti Top Island
Ti Top Island is world-famous for its unique crescent-shaped white sand beach and its challenging 400-step hike to a panoramic summit. From the top, visitors are rewarded with a 360-degree vista of the entire bay, including the mountain peaks that house Trinh Nu cave.
