October to April for milder, drier weather and clearer skies; May to September is warmer with more rain and higher risk of storms but also lush scenery and calmer seas some weeks.

Tropical monsoon climate: warm and humid year-round. Winter (Nov–Feb) is cooler and sometimes misty; summer (Jun–Aug) is hot, humid and can bring heavy rain and occasional typhoons.

There is no universal UNESCO 'entry fee' for Ha Long Bay itself; visitors typically pay for cruises, boat tickets, and small entrance fees for specific attractions (e.g., caves, Cat Ba National Park). Cruise boarding is scheduled throughout the day; most caves and island attractions are open roughly from early morning to late afternoon (approx. 7:00–17:00), but hours vary by site and operator.

Nearest major airports: Cat Bi International Airport (Hai Phong) ~50–70 km away, and Noi Bai International Airport (Hanoi) ~150–170 km (3.5–4.5 hours by road). Regular shuttle buses, private transfers, trains to Ha Long (limited), and express ferries from Hai Phong/Cat Ba connect the region. Many visitors travel from Hanoi by road or take a combined transfer to the cruise pier (Tuan Chau, Bai Chay, or Hon Gai).

2–3 days for a typical overnight cruise and island visits; 4–5 days if you want to include Cat Ba Island, trekking, and more remote bays (Lan Ha or Bai Tu Long).

Light, breathable clothing, a light rain jacket, swimwear, sturdy sandals or walking shoes, sunhat and sunglasses, reef-safe sunscreen, insect repellent, a small dry bag for electronics, and a power bank.

Try local seafood specialties such as grilled squid, steamed fish, and chả mực (squid cake). Popular souvenirs include cultured pearls, dried seafood, local lacquerware, and handcrafts. Respect sustainable choices—avoid products made from endangered species.
