Ha Long Bay

Why Visit Ha Long Bay

Ha Long Bay is a UNESCO World Heritage site covering 1,553 square kilometers with 1,600-2,000 limestone karsts and islets rising from emerald water. It's the single most-visited natural attraction in Vietnam, and the boat trips that service it range from luxury junks to cheap day boats.

The Two Bays

There are actually two adjacent bays: Ha Long Bay (the main, most crowded) and Lan Ha Bay (quieter, emptier, equally spectacular). Most luxury cruises now operate in Lan Ha Bay. If your cruise says "Ha Long" but routes through Lan Ha, you're getting the better half.

Types of Cruises

Day Cruise (6-8 hours) — US$30-60. Cheapest option. Leaves from Tuan Chau Marina, visits the main caves (Sung Sot, Thien Canh Son), does kayaking, lunch included. The boat is crowded and the route is the same as everyone else's. Good for budget travelers on a tight schedule.

Overnight Cruise (2 days / 1 night) — US$100-200. This is the sweet spot. You get sunset on the bay, sunrise the next morning, a quieter evening, and a smaller group (20-40 people). Most include a cave visit, kayaking, squid fishing, and a cooking demo.

2-Night Cruise (3 days / 2 nights) — US$200-400. Goes deeper into Lan Ha Bay, visits Cat Ba Island, and includes more kayaking and beach time. The second day is noticeably emptier.

Luxury Junk (2-3 nights) — US$400-1,000+. Wooden junks with private balconies, fine dining, butler service. Paradise Luxury, Au Co Cruises, and Heritage Line are the top operators. Good for honeymoons and celebrations.

What NOT to Book

The US$15 bus + boat combo from Hanoi — you get a bus ride, a crowded boat serving bad food, and 2 hours on the bay. Any cruise that doesn't specify the route — make sure you're going to Ha Long or Lan Ha, not the traffic-jammed Vung Ha area. A cruise that charges extra for kayaking — good ones include it.

When to Go

October to April is the best weather. March and April are the sweet spot — calm seas, clear skies, fewer tourists. May to September is the rainy season with occasional typhoons. December to February is cold (15-20°C) and sometimes foggy, which can obscure the karsts entirely.

How to Book

Book online through Sinh Tourist, Bukit (handles Cat Ba trips well), or your hotel if you trust them. In Hanoi, most hotels in the Old Quarter book cruises — they take a commission, but small operators get you better deals than large agencies. Never pay the "walk-up" price at Tuan Chau Marina.

The Honest Truth

Ha Long Bay is beautiful and extremely touristy. The photos you've seen are cropped to exclude the other 200 boats. Go with realistic expectations — the water is emerald, the karsts are spectacular, but you will not be alone. The magic happens at sunset when the day boats leave. If you can afford one night on the water, do it.
