Rafting, paddling, cruising, sailing or whale watching – no matter the method, many travelers love getting out on the water for some fun in the sun. If your clients’ vacation of a lifetime involves spending time on a boat, we’ve made things easy for you by rounding up five of our favorite experiences on the world’s rivers, oceans and lakes, pulled from our database of thousands of bookable tours and attractions.

Sometimes the request from clients you may get is that they need to rebalance, relax in a different way than they usually do. Recommend them this 45-minute yoga class on the sundeck of the Emperor Dragon Boat. After this invigorating wake-up, your clients can relax over a cup of tea and traditional Hue cakes while enjoying the views of Hue’s scenic Perfume River and its photogenic Trang Tien Bridge.

All the magic and romance of Paris are on full display during this gourmet dinner cruise along the iconic Seine River. Your clients will board the Bateaux Parisiens sightseeing boat beneath the shadow of the Eiffel Tower and sip on a glass of welcome champagne as they set sail, gliding past some of the City of Lights’ top monuments – the Louvre Museum, Notre Dame Cathedral and Musée d’Orsay among them. As your clients gaze out the windows of this luxury riverboat, feast on a three-course French menu.

Iceland is famous for its wildlife, and few places on the planet are better for whale watching than the waters of Faxafloi Bay off the coast of Reykjavik. Your clients will board a rigid inflatable boat for a 2-hour whale watching excursion, where they will look for minke and humpback whales, white-beaked dolphins, porpoises and even seasonal puffin colonies.

A day of fun in the sun doesn’t get much better than one spent in the Whitsunday Islands at Whitehaven Beach. Your clients just have to grab their sunglasses and board a motorized raft at the Airlie Beach marina for a relaxing ride to the islands. Upon arrival, they will be able to dig their toes into the 4 miles (7 kilometers) of sugar white sand or strap on a snorkel to observe the array of colorful marine life among the nearby coral reefs.
