UNESCO World Heritage limestone karsts and emerald waters
Updated
Ha Long Bay is one of Vietnam's most iconic natural landmarks, a UNESCO World Heritage Site since 1994 and recognised again in 2000 for its outstanding natural values. Spread across roughly 1,553 square kilometres of the Gulf of Tonkin in Quang Ninh Province, the bay contains an estimated 1,969 limestone islands and islets rising dramatically from calm, emerald-green waters.
Ha Long Bay is in Vietnam, Southeast Asia, about 140 km east of Hanoi in a straight line. Its coordinates are 20.9101° N, 107.1839° E.

Over millennia, rain and sea erosion have sculpted the karst formations into arches, grottoes, and hollow caves, creating a landscape that feels otherworldly at every turn.
The name Ha Long translates loosely as 'where the dragon descends into the sea', a reference to the Vietnamese legend that a great dragon and her young descended here, their bodies forming the islands that protect the coast. Today, the bay draws around eight million visitors annually who come to experience its extraordinary scenery, explore its cave systems, and cruise overnight among the towers of rock.
The most popular way to experience Ha Long Bay is on a multi-day cruise aboard a traditional junk boat or a modern luxury vessel. Overnight cruises depart from Tuan Chau Marina or Cai Rong Harbour and typically include guided cave tours, kayaking through hidden lagoons, and stops at floating fishing villages. Sung Sot (Surprise) Cave, Thien Cung (Heavenly Palace) Cave, and the iconic Titop Island viewpoint are among the most visited spots. Shorter day cruises operate from Ha Long City for visitors with limited time.
Beyond the water, the gateway city of Ha Long (formerly known as Hon Gai) has developed a solid tourism infrastructure with international hotels, seafood restaurants, and the Sun World Ha Long Park entertainment complex. The adjacent Cat Ba Island offers national park trekking, rock climbing, and a more rugged experience for independent travellers.
The best time to visit Ha Long Bay is from October to April, when skies are clearer and temperatures are comfortable. May to September brings warmer weather but also the risk of typhoons and reduced visibility. Travel is possible year-round, though rough seas can occasionally suspend cruise operations between November and March. Ha Long City is served by Van Don International Airport, and high-speed trains and buses connect the region to Hanoi in approximately three hours.
When to go
Ha Long Bay's emerald waters and 1,600 limestone islands look magical year-round, but the weather makes or breaks an overnight cruise. The dry, cool season from October to April is the sweet spot - calmer seas, low humidity and clear(ish) skies that show off the karst silhouettes. This is peak season for good reason.
Attractions
The headline experience is the overnight cruise - waking up to mist drifting between the karsts is unforgettable. But the bay rewards exploration beyond the boat deck: sea caves, hidden lagoons, a floating village and a surprisingly good beach. Most travellers pair it with Hanoi and a side trip to Sapa or Hoi An. For the deep dive, see our Ha Long Bay cruise guide.
The bay's largest and most spectacular cave, set across three vast chambers on Bo Hon Island. Stalactites, natural skylights and surreal rock formations lit by coloured lights - a 45-minute walk up steps and through the mountain. Almost every cruise stops here.
Included on most cruises; ~20-minute climb, wear non-slip shoes.
The only way into the hidden “emerald” lagoons enclosed by karst walls - paddle through low cave tunnels into mirror-still pools where monkeys sometimes climb the cliffs. Luon Cave and the area around Cong Dam are favourites. No experience needed; double kayaks are standard.
Often free on cruises; ~100,000-200,000 VND ($4-8) if you rent independently.
A postcard island with a sweeping viewpoint reached by 400-plus stone steps, plus a tidy swimming beach at its base named for cosmonaut Gherman Titov. The climb is steep but the panorama of the bay is the classic shot.
Beach free; viewpoints open daily. Avoid the midday crowd - go early.
One of the last of the bay's traditional fishing villages, where families live in houseboats moored among the karsts. Row a bamboo boat through the village and floating school - a quieter, more cultural alternative to the busy beaches. The bamboo-boat row is usually included on cruises.
The quieter, lesser-known sister of Ha Long Bay - same limestone karsts and beaches but far fewer boats. Many mid-range and luxury cruises now route here. If you want to stay on land, Cat Ba Island offers hiking, monkey-spotting and a laid-back base.
For the wow factor, a 25- or 40-minute scenic seaplane flight from Hanoi reveals the full scale of the bay's 1,600 islands from above. It also doubles as the transfer - you land directly on the water. A splurge, but the single best way to grasp how vast the archipelago is.
From ~4,000,000 VND ($160) for a 25-minute scenic flight.
Transport
Ha Long Bay itself is a body of water - you explore it on a cruise, and everything else is about getting to and from the port. Most travellers come from Hanoi; the new highway has cut the drive dramatically. Once your cruise ends, Bai Chay (Ha Long City) is walkable, but you'll want transport for anything further.
Ha Long Bay pairs perfectly with a northern Vietnam loop - Hanoi for the Old Quarter, the rice terraces of Sapa, and the karst valleys of Ninh Binh. See our 5 days in Vietnam itinerary for a ready-made route.
Accommodation
For most travellers the boat is the stay - an overnight cruise is the defining Ha Long Bay experience. If you prefer dry land, the bay, Cat Ba and nearby Da Nang-style beach towns have solid options at every budget.
The classic experience. Budget day boats from ~$40; mid-range 2-day/1-night cruises $90-180; luxury (Aston, Stellar, Paradise) $250-500+. Book by route (Ha Long vs the quieter Lan Ha Bay) and cabin type.
The main tourist hub closest to Tuan Chau pier. High-rise hotels, the Sun World complex, beaches and seafood - practical but not atmospheric. Best for a night before or after your cruise.
The largest island, a laid-back base for exploring Lan Ha Bay on day boats. Cheap guesthouses, a national park with hiking and monkey-spotting, and a fraction of the crowds. The backpacker favourite.
The gated resort island and main cruise departure point. Upscale hotels, villa complexes and theme-park attractions - convenient if your cruise leaves from here and you want a splurge night.
Food & drink
Your meals are largely dictated by where you sleep - cruises include set menus and seafood feasts, while Ha Long City's restaurants and Bai Chay market serve northern Vietnamese staples at low prices. Don't leave without trying the local seafood.
Ha Long squid sausage (cha muc) - the signature local snack, ground squid steamed or fried into springy patties, best dipped in chilli salt. Fresh seafood - grilled prawns, crab and geoduck sold by weight at Bai Chay's seafood street. Bun beo - tiny flower-shaped rice-flour cakes with dried shrimp and crispy pork skin, a regional specialty.
On the cruise, expect multi-course Vietnamese and international set dinners and a sunset happy hour. Vegetarian options are standard if you request them when booking.
Plan your trip
UK and most EU passports get 45 days visa-free; US, Australian and Canadian passports need an e-visa ($25, up to 90 days, as of November 2026) - see our Vietnam visa guide. The currency is the Vietnamese dong (VND). English is spoken on cruises and in hotels. Pack layers - the bay can be cool and misty even in summer - and bring motion-sickness tablets if you're prone.
