Introduction
The Cat Ba Archipelago (Quần Đảo Cát Bà) is a cluster of 367 islands located in the Gulf of Tonkin, off the coast of Hai Phong. Its largest island, also named Cat Ba, serves as the primary hub and is home to a national park that constitutes over half of its area. Designated as a UNESCO Man and Biosphere Reserve, the archipelago is a critical center for biodiversity, most notably for the protection of the critically endangered golden-headed langur.
What you'll love about the Cat Ba Archipelago
Kayaking through the silent, emerald waters of Lan Ha Bay, navigating between towering limestone karsts that rise directly from the sea. The feeling of accomplishment and the stunning 360-degree view after a sweaty hike to the top of Ngu Lam Peak in the national park. Ending the day at Cannon Fort, watching the sun dip below the horizon, painting the hundreds of islands in hues of orange and purple.

Tips from locals
🗓️ Avoid weekends and public holidays if possible, especially from June to August. The island becomes extremely crowded with domestic tourists, leading to higher prices and fully booked accommodation and ferries. A weekday visit offers a much more peaceful experience.
⛴️ When booking a Lan Ha Bay tour, clarify every inclusion. Ask specifically if kayaking, national park entrance fees, and all meals are part of the price. Cheaper tours often have hidden costs that add up.
💵 Bring enough cash. While ATMs are available in Cat Ba Town, they can be unreliable or run out of money. Many smaller restaurants, shops, and tour operators do not accept credit cards.
🛵 When renting a motorbike, take detailed photos or a video of the bike in front of the rental agent, pointing out any pre-existing scratches or damage. This prevents potential disputes over "new" damage when you return the vehicle.
🛶 Some boat tours in Lan Ha Bay may try to cut the trip short or take you to crowded areas to save fuel. Use reputable operators recommended by your hotel or established online travel agencies, and confirm the planned route on a map before departing.
