Where Is Cat Ba Island?
Nicknamed the “Pearl of the Gulf of Tonkin,” Cat Ba Island is the largest island in the region and belongs to Hai Phong City, about 150 km east of Hanoi. Nestled among more than 300 smaller islets in Lan Ha Bay, Cat Ba shares the same spectacular limestone karst formations as nearby Halong Bay, yet it retains a far more laid-back and authentic vibe.
The island is a unique blend of dramatic seascapes and lush green hills. Small fishing villages dot its coastline, while jungle-clad peaks rise in the background. Despite being increasingly popular, Cat Ba still feels much less crowded than Halong, making it a perfect escape for travelers who want both natural beauty and cultural immersion.
👉 Fun fact: Both Halong Bay and Cat Ba Island are recognized by UNESCO for their geological, cultural, and ecological importance. Cat Ba is also part of a designated biosphere reserve, thanks to its rare wildlife and pristine forests.
What Does Cat Ba Have in Common with Halong Bay?
Cat Ba is often called Halong Bay’s hidden twin—offering the same breathtaking scenery with a calmer, more local feel.
Here’s what they share:
- 📍 Location – Both lie in the Gulf of Tonkin, surrounded by hundreds of limestone islands.
- 🌍 UNESCO status – Both are part of a World Heritage-listed landscape.
- 🏞️ Scenery – Towering limestone cliffs, emerald-green waters, hidden caves, and floating fishing villages.
But the difference is clear: tourist crowds. While Halong Bay welcomes thousands of visitors daily, Cat Ba and Lan Ha Bay remain relatively peaceful. Around one-third of Cat Ba is protected as Cat Ba National Park, home to rich biodiversity, rare primates such as the golden-headed langur, and untouched rainforest.
If Halong Bay is about grandeur and scale, Cat Ba is about intimacy and authenticity—where nature, culture, and adventure meet.

How to Get to Cat Ba Island
Reaching Cat Ba is easier than ever, thanks to a range of transport options that suit different budgets and travel styles:
- 🚍 From Hanoi or Ninh Binh: The most common way is a bus + speedboat or ferry combo, taking around 3.5–4.5 hours. Many companies offer direct “through-tickets” that include the bus to Hai Phong or Got Pier and a connecting speedboat across to Cat Ba Town.
- 🚗 Private Car or Taxi: Ideal for families or groups who want comfort and flexibility. Travel time is about 3.5 hours from Hanoi, and you can arrange hotel pick-up and drop-off.
- ✈️ From Ho Chi Minh City or Da Nang: Fly into Hai Phong’s Cat Bi Airport, which has daily flights from Vietnam’s major cities. From there, it’s about 45 minutes to Got Pier and another short ferry or speedboat ride to the island.
👉 Tip: If you’re short on time, book a package that includes transport + boat transfer directly to Cat Ba. It saves the hassle of arranging separate tickets.
When Is the Best Time to Visit Cat Ba?
Cat Ba is a year-round destination, but each season brings its own unique atmosphere:
