Dau Go (Driftwood) Grotto

Dau Go Grotto is found on Driftwood Island, formerly known as Canh Doc Island. The name Driftwood Grotto comes from the popular story of the resistance war against the Nguyen Mong aggressors. In a decisive battle, Tran Hung Dao was given an order to prepare many ironwood stakes to be planted on the riverbed of the Bach Dang River. The remaining wooden pieces were found in the grotto and, as a result, the grotto was given its present name. The entrance is reached via 90 steps up the island. The grotto is divided into three main parts. In the first chamber, many forms can be seen in the rock, depending on the imagination of the observer. In the middle of the chamber, on the top of the pillar, there appears to be a monk draped in a long, dark cloak, with his right hand clasping a cane. Moving into the second chamber, visitors pass through a narrow "door", naturally formed through erosion. The light here is mysterious, and new images appear in the stone. At the end of the grotto is a well of clear water surrounded by four ancient walls.

In this grotto, there remains an engraved stone stele singing the praises of Halong Bay ordered by Emperor Khai Dinh when he came to visit the grotto in 1917. Dau Go is 40 minutes from Bai Chay. Admission is 15,000 VND per person, 5,000 VND for children under 15, and children under 6 are free.

Trinh Nu (Virgin) Grotto-Trong (Male) Grotto

The Virgin Grotto is situated in the island range of Bo Hon, in the system comprised of the Surprise Grotto, Dong Tien Lake, and Luon Grotto. The grotto is 15 km south of Bai Chay Beach. For some fishermen, the Virgin Grotto is home, while for young lovers it is a popular romantic rendezvous site.

According to legend, there once was a beautiful fisherman's daughter, whose family was so poor that they were in service of the rich administrator of the fishing zone, who forced the family to give him their daughter as a concubine. However, the fisherman’s daughter already had a lover and refused to marry the administrator. The administrator got angry and exiled her to a wild island where she suffered from hunger and exhaustion. One frightful night she turned to stone. On this same night, her lover, knowing of her danger, rowed his boat in search of her. However, a tempest destroyed his boat, and he floated to a nearby island. In a flash of lightening, he saw his lover in the distance, but his calls were driven away by the wind. In his final exhaustion, he also turned to stone (today’s Male Grotto).

When visiting the Virgin Grotto, you can still see the petrified girl with her long hair hanging down and eyes looking towards the mainland. Opposite the Virgin Grotto, the Male Grotto is still home to the lover whose his face is turned towards his mate. At times, his passionate calls and blows against the walls of the grotto can still be heard.

Thien Cung (Heavenly Palace) Grotto

This recently discovered grotto is one of the most beautiful in Halong Bay. Thien Cung is situated on the southwest side of the bay, 4 km from the wharf outside of Halong City. It is located in a small range of islands that resemble a throne embracing two superb grottoes at its core. The way to Thien Cung is perilous, covered on both sides by thick forest. After entering a narrow gate, the magnificent, 130 m long grotto opens up.

According to legend, a beautiful young lady named May (cloud) caught the eye of the Dragon Prince and he fell in love with her. They were betrothed and got married in the very center of the grotto. All of the scenes of their wedding, which lasted for seven days and seven nights, have been seemingly fossilized in the grotto.

In the center, there are four large pillars supporting the "roof of heaven". From the base to the top, many strange images seem to exist in the stone, including birds, fish, flowers and even scenes of human life. On the north wall of the grotto, a group of fairies seems to be singing and dancing in honor of the wedding. Under the immeasurably high roof, stalactites form a natural stone curtain. There is also the sound of a beating drum made by the wind blowing through the stone.

In the last chamber of the grotto, a natural gushing stream of water babbles throughout the year. Here there are three small ponds of clear water. One path meanders out of the grotto.

Quang Hanh Grotto

Located 9 km west of Cam Pha, Quang Hanh Grotto is the longest grotto in Halong Bay. It is 1,300 m long, and stretches throughout the stone mountain of Quang Hanh. The French named it "Le Tunnel," or Tunnel Grotto.

Quang Hanh Grotto is accessible by either boat or car, but the entrance only appears when the tide is out. Ba Co Shrine (shrine of three girls) is in the grotto beside a smooth stone block. Legend tells that three girls, who were once journeying on the sea, came to the grotto to take shelter from the rain. They were so engrossed with the beauty of the grotto, that they did not notice the rising tide. They drowned, only to become water goddesses.

Quang Hanh Grotto is extremely beautiful. A small boat will take you through the stone passageway by flashlight, casting magical colors on the hanging stalactites.
