With over 1,900 limestone islands and islets, Halong Bay is a paradise for nature lovers and adventure seekers alike. Each island has its own charm — from golden beaches and panoramic viewpoints to hidden caves and tranquil lagoons.
If you’re planning a cruise or day trip, here are some of the best islands to visit in Halong Bay, from the famous Titop and Soi Sim to lesser-known gems waiting to be discovered.
1. Titop Island – A Perfect View from the Top
Named after the Russian astronaut Gherman Titov, who visited Vietnam in 1962, Titop Island is one of the most iconic spots in Halong Bay.
A short hike up 400 stone steps rewards visitors with a 360-degree panoramic view of the emerald waters and limestone karsts — one of the most breathtaking sights in all of Vietnam.
After the climb, relax on the crescent-shaped sandy beach below, where you can swim, sunbathe, or rent kayaks. The island’s convenient location (just 8 km from Bai Chay Harbor) makes it a must-stop for both day cruises and overnight tours.
Best for: Photography, hiking, and swimming
Travel tip: Visit early in the morning or late afternoon to avoid crowds and enjoy the soft golden light for photos.
2. Soi Sim Island – Nature’s Hidden Retreat
Just across from Titop, Soi Sim Island offers a quieter alternative with lush green hills and calm turquoise waters.
The island’s untouched forest is home to several native plant species, making it a great spot for short nature walks and eco-tourism. Soi Sim Beach is smaller but incredibly peaceful — ideal for travelers seeking relaxation away from the busy cruise routes.
Best for: Relaxation, swimming, and light hiking
Travel tip: Combine your visit to Soi Sim with Titop Island for a balanced mix of adventure and tranquility.
3. Tuan Chau Island – The Gateway to Halong
Tuan Chau Island serves as the main tourist hub and departure point for most Halong cruises. But beyond being a gateway, it’s also a destination in itself.
The island features luxury resorts, water sports, restaurants, and entertainment complexes, making it perfect for those who prefer comfort and convenience. You can enjoy activities such as jet-skiing, kayaking, and cultural shows in the evening.
Best for: Families, couples, and travelers seeking resort-style stays
Travel tip: Stay overnight at Tuan Chau before or after your cruise for a seamless experience.
4. Bo Hon Island – Home of Legends and Caves
If you love exploring caves and myths, Bo Hon Island is a must-visit. It’s home to some of Halong’s most famous caves, including:
- Sung Sot (Surprise) Cave – The largest and most impressive cave in the bay
- Trinh Nu (Virgin) Cave and Trong (Male) Cave – Two connected caverns tied to a touching love legend
Bo Hon is also a paradise for photographers and adventurers, with towering cliffs, hidden lagoons, and crystal-clear waters surrounding it.
Best for: Cave exploration and cultural legends
Travel tip: Wear comfortable shoes for cave visits and bring a flashlight if you want to explore smaller grottoes.
5. Quan Lan Island – Off-the-Beaten-Path Beauty
For those who want to escape the crowds, head to Quan Lan Island, located in Bai Tu Long Bay (northeast of Halong).
With long stretches of white sand beaches, traditional fishing villages, and peaceful countryside, Quan Lan feels like a different world. You can rent a bicycle to explore the island, visit ancient temples, and watch local fishermen bringing in their catch.
Best for: Authentic local experiences and beach lovers
Travel tip: Quan Lan is accessible by speedboat from Cai Rong Port — ideal for a 2-day side trip from Halong City.
6. Cat Ba Island – The Adventure Hub
Technically part of Cat Ba Archipelago in Lan Ha Bay, Cat Ba Island is often included in Halong cruise itineraries.
It’s the largest island in the area, offering hiking, rock climbing, kayaking, and national park exploration. Cat Ba Town also has vibrant nightlife, seafood restaurants, and local markets.
Best for: Adventure seekers and nature enthusiasts
Travel tip: Spend at least one night on Cat Ba to explore both the national park and Lan Ha Bay’s quiet waters.
7. Ngoc Vung Island – The Island of Pearls
Legend has it that Ngoc Vung Island once shimmered with light from countless pearls in its waters. Today, it’s known for its long, unspoiled beach and peaceful atmosphere.
This island offers a glimpse into rural life, with small villages, shrimp farms, and friendly locals. It’s an ideal place for travelers who want to disconnect and enjoy a slower pace.
Best for: Cultural immersion and serenity
Travel tip: Try local seafood dishes — especially grilled squid and steamed clams — freshly caught from the surrounding bay.
From world-famous viewpoints on Titop Island to the quiet charm of Ngoc Vung and Quan Lan, Halong Bay’s islands offer endless diversity. Whether you’re chasing adventure, relaxation, or authentic local life, there’s an island for every kind of traveler.
As you sail through the emerald waters, take time to step ashore — because each island in Halong Bay holds a story waiting to be discovered.
