Your cruise through Halong Bay wends among otherworldly karst formations and opens up views of one stupendous seascape after another. Be sure to key on the following attractions, as well. Changeable conditions and tides can affect the route, visibility and anchorage, but the following spots should be visible from the sun deck.

Sung Sot GrottoEarly French tourists who wandered among the 10,000 square meters of this cavern dubbed this space "Grotte des Surprises", or Surprise Cave. Sung Sot more than lives up to its name on Bon Ho Island, situated right at the heart of the UNESCO-recognised World Heritage area. From the wharf, 50 steep stone steps lead up to the entrance, but the view is worth the effort. The grotto features thousands of stalactites and stalagmites. Paths, lights and signposts guide you through two caves which continue to offer yet more twists, turns and, yes, surprises throughout.

Cua Van and Vung Vieng Floating VillagesSeven hundred people live at Cua Van in a calm bay surrounded by limestone karsts. Most, not surprisingly, earn their living by fishing and spend almost their entire existence living on the water. The following day you will also pass Vung Vieng Floating Village. Sixteen hundred people live on Halong Bay itself in similar communities.

Hang Trong AnchorageThe Emeraude anchors at Hang Trong. Hang Trong , or Drum Cave, refers to a nearby cave that earned its name as a result of the sound made as the wind blows through its stalagmites and stalactites. The waters here are quiet for swimming and there is lots to explore by kayak. Depending on conditions there are as many as five potential anchorage spots. Though Hang Trong is the most used, conditions may mean the vessel's captain opts for another site.

Titov IslandTitov Island was named after an illustrious visitor, Gherman Stepanovich Titov, who visited the spot on November 22, 1962 alongside President Ho Chi Minh. The Soviet astronaut was the second person to orbit the earth. Titov himself returned some 35 years later on June 27, 1997. The island is noted for a beautiful crescent-shaped beach that's popular with swimmers and water sports enthusiasts. You may also hike 420 steps up to a pavilion at the summit for a panoramic view of Halong Bay.

Transferring from the Emeraude onto our cruising boat you will cruise down through majestic Ha Long Bay into the more intimate and labyrinthine Lan Ha Bay. Spend the morning exploring the astonishing beauty of Lan Ha Bay’s less traveled beaches, archways, and wonderful lagoons. We provide a hearty lunch during which everyone can chat about their own experiences and feelings from the morning’s adventures.

After lunch, you’ll de-board at the amazing Moody’s Island beach. With sea water caressing two shorelines beneath massive limestone cliffs, you’ll have the opportunity to get up close and personal with the beauty of Lan Ha Bay as you're certified climbing guides outfit you with safe and comfortable UIAA standard climbing harnesses and rock climbing gear. Your guides will set up top-rope systems on a number of different climbs (or ‘routes’) and after a short safety and instructional talk you may ascend the rock face safely and worry free. With the coaching of our experienced guides, climb as high as you’d like overlooking the emerald waters of Lan Ha Bay and enjoy a spectacular view unlike any other. Or swimming and lounging may suit some, you are free to take it easy in this spectacular spot if you prefer. Take it as it comes and our guides will be there to help make it happen!

Enjoy the setting sun as you cruise back to The Emeraude for a well deserved evening Dinner under the stars of Ha Long Bay and an astounding day to remember
