3 Days / 2 Nights
Lan Ha Bay & Cat Ba3 Days / 2 Nights aboard the Diana Cruise.
The three-day Diana itinerary takes the same 6-star superyacht deeper into the bay, adding a day among the quieter reaches of Lan Ha Bay and Cat Ba Island. Alongside the Bright Cave, kayaking and swimming, you'll cycle through Viet Hai Village and explore the landscapes around Cat Ba National Park, with more time for the infinity pool, sky bar and spa. It's the most complete way to experience the newest and most luxurious cruise on the water.

The cabins

Top decks
A four-season infinity pool, a rooftop sky bar, a panoramic restaurant and a gym looking out on the karsts.
The bay
Two days in Lan Ha Bay taking in Duck Islet, Tra Bau and the Bright Cave, reached by bamboo boat.

Two days or three, on this boat.
2 days, 1 night
An afternoon and evening on the water, a night at anchor and a morning sail out. The length most travellers choose.
3 days, 2 nights
Day two is when the fleets disperse and you reach the further coves - the bay at its most peaceful.

Our experience of
We've hosted guests aboard the Diana and been over her ourselves. She's a new six-star superyacht, and the cabins are the headline - private balconies, a jacuzzi looking over Lan Ha Bay, and interiors that guests describe as among the nicest rooms they've stayed in, at sea or ashore.
On the water it's an easy, relaxed rhythm: kayaking and swimming stops, a cooking class that guests single out, and quieter touches like tai chi, a cocktail class and live music in the evening. The service is the other thing people raise with us - attentive and warm without being formal. She sails the calmer Lan Ha and Ha Long routes, so there's room to slow down.
What we've found: choose the Diana if a private balcony jacuzzi and a genuinely lovely cabin matter to you. It suits couples and families who want comfort and a soft pace over a packed itinerary.

About this boat, and about cruising the bay.
There are 6 cabin grades aboard Diana Cruise: Diana Junior Balcony, Diana Senior Balcony, Diana Executive Balcony, Diana Royal Family Suites, Diana Halong Suite and Diana Lan Ha Suite. Sizes run from 34m² to 65m². The full table of sizes, beds and outlook is on this page.
Diana Cruise sails Lan Ha Bay & Cat Ba. If you are still deciding between the bays, our comparison of Ha Long, Lan Ha and Bai Tu Long sets out how they differ in traffic, scenery and how far you travel to reach them.
Embarkation is at Tuan Chau. Boarding starts around 08:20-08:50. The hour-by-hour itinerary above gives the timings for the day.
Both run the same boat and the same cabins. The 3 days / 2 nights adds a second full day, which is when the day boats have gone and the itinerary reaches the quieter water. The 2 days / 1 night covers the headline sights and gets you back to Hanoi a day sooner.
Road transfer from Hanoi takes roughly two and a half to four hours depending on which harbour the boat uses. We arrange the transfer with the cruise as one booking, so the timings match the boarding window rather than leaving you to work them out.
Overnight cruises in Ha Long normally include the cabin, all meals on board, the guided activities in the itinerary above and the bay entrance fees. Drinks, spa treatments and the transfer are the items that vary most between boats. We confirm exactly what is and is not included for this boat in writing before you pay, because it differs by operator and by season.
Ha Long Bay closes to cruise traffic when the harbour authority says so, usually for storms. If that happens we move the date or refund the cruise - you are never held to a sailing that cannot run. Our refund policy sets out the detail.
Yes. Most boats take children of any age and price them in bands rather than as adults, and many have family cabins or connecting rooms. Tell us the ages when you enquire and we will say which boats suit and what each one charges.
Vegetarian, vegan, gluten-free and allergy requirements are all workable, but they need to be given at booking rather than on the day - the boat provisions before it leaves harbour and cannot restock at sea.
October to April is the settled season, with clear air and cool mornings. May to September is warmer and better for swimming, with a higher chance of a storm closing the bay. Our guide to Ha Long Bay goes into the months in more detail.
We'll build the Diana Cruise into a complete, private Northern Vietnam itinerary, planned and run for you, with the right cabin and every transfer handled.
