Hidden Secrets of Halong Bay and Beyond: Islands and Caves Few People Know

Soi Sim Island – A Pristine Gem in Central Halong

Soi Sim Island retains its wild, untouched charm with powdery white sand, crystal-clear water, and a rich ecosystem of birds and monkeys. Unlike the popular Titop Island, Soi Sim is far less crowded. Climb over 400 steps to reach its summit for a panoramic view of the bay—ideal for unique travel photos few tourists have.

Ba Ham Lake – The Hidden Lagoon of Lan Ha Bay

Located on Dau Be Island in Lan Ha Bay, Ba Ham Lake is a serene lagoon accessible only by kayak or small boat through cave tunnels. Encircled by vertical cliffs and lush rainforest, it offers a tranquil atmosphere for swimming and discovering marine life. Though geographically beyond Halong proper, it’s part of the wider UNESCO-recognized heritage seascape shared between Halong and Cat Ba.

Thien Canh Son Cave – Bai Tu Long’s Best-Kept Secret

Nestled in Bai Tu Long Bay, Thien Canh Son is a captivating alternative to the busy Sung Sot Cave. Located on Cong Do Island, this hidden marvel features three limestone chambers with naturally formed stalactites that resemble lotus flowers and seals. The hike through a forest path adds to its peaceful, untouched charm.

Ban Chan Beach – A Secluded Paradise for in Bai Tu Long (Currently Unavailable)

Accessible only by small boat, Ban Chan Beach is a peaceful stretch of sand surrounded by dramatic cliffs and green forest. However, as of June 2025, Ban Chan Beach is not officially licensed to serve tourists in Halong Bay. While it remains a picturesque and memorable location, it is not currently open for tourism activities pending regulatory updates.

Currently, only Titop Beach is approved for tourist use in Halong Bay. Plans are underway to reopen additional beaches, including Soi Sim Island, Hang Co (Thien Canh Son area), and Hang Trinh Nu, in 2025 as part of an expanded conservation and tourism strategy.

Sung Sot Cave – Discovering New Angles of a Classic Site

While Sung Sot Cave on Bo Hon Island is one of the most visited caves in Halong Bay, it still holds surprises. The two main chambers are home to fascinating stalactites and stalagmites shaped like elephants, dinosaurs, and other creatures—all changing form with the play of natural light. With an observant eye, each visit offers something new.

Floating Villages and Secret Islands – A Cultural Side of the Bay

Vung Vieng and Cua Van are two of the last remaining floating villages in the region. Visiting these communities offers insight into traditional fishing culture and the daily rhythm of coastal life. Beyond the villages, less-traveled islands like Ngoc Vung, Quan Lan, and Cai Tai invite exploration, local seafood feasts, and quiet moments of connection with nature.

Kayaking Adventures – Accessing the Inaccessible

One of the best ways to uncover hidden gems in the Halong - Cat Ba seascape is by kayak. Paddle through narrow passageways, under limestone arches, and into secluded lagoons that larger boats can’t reach. It’s the most intimate way to encounter the serenity and mystery of the bay’s lesser-known corners.
