With breathtaking views and popular destinations, here are 10 of the world's top scenic boat rides.

1. Golden Gate Ferry – San Francisco to Sausalito, California.

The San Francisco Bay is undoubtedly one of the most picturesque vistas on the West Coast, and experiencing it by ferry is both affordable and a perfect way to explore the beautiful towns north of the city's peninsula. Start at the San Francisco Ferry Building, a tourist destination in its own right, with a renowned farmers' market three days a week (Tuesday, Thursday and Saturday) and a great selection of shops. Board the ferry to Sausalito for a 30-minute ride – it sells wine and beer, so enjoy a drink while taking in the views of the Golden Gate Bridge and the bay. Cyclists can bring bikes for free, so VirtualTourist members recommending taking or renting a bike so you can tour Sausalito's quaint town before returning to the big city.

2. Star Ferry – Hong Kong, Hong Kong

The most well-known ferry ride in Asia, the Star Ferry connects Hong Kong Island with Kowloon Peninsula to the north. Ferries leave from both the Central and Wan Chai areas of Hong Kong Island, arriving at Tsim Sha Tsui's Star Ferry Pier on Kowloon. It's a fantastic way to take in Hong Kong's skyline during the day and with ferries departing as late as 10.30pm, it's also a great way to see the city's nightly light display, A Symphony of Lights. The Star Ferry also has a harbour tour option which circles Victoria Harbour and lasts an hour. It offers Single Ride Round Trip tickets during the day, night, and special Symphony of Lights Harbour Cruise.

3. Venice Vaporetto – Venice, Italy

While the most famous boats in this region may be gondolas, few rides in the world will give you the eyeful of a Vaporetto in Venice. Equivalent to a water taxi, these boats are an easy way to admire all the mansions and buildings that overlook the Grand Canal and the lagoon while also being helpful for gaining your bearings when first arriving to the canalled city. Although expensive, every visitor to Venice should ride a vaporetto at least once.

4. Cruising Milford Sound – South Island, New Zealand

Internationally renowned as one of the most beautiful waterways in the world, Milford Sound in New Zealand had to be included. Discovered by the Maori people more than 1000 years ago and located in South Island's Fjordland National Park, the majestic landscape can be accessed by road, but should be experienced on the water. The sound is bounded by steep cliffs and dense rainforest on either side, with Mitre Peak towering 1692m above sea level as the focus of many photographs. There are a number of day cruises available to experience the sound as well as kayaking and nature guides. Sightseeing tours from Queenstown and Te Anau to Milford Sound are popular as well.

5. Washington State Ferries to the San Juan Islands – Anacortes, Washington.

Boasting a great variety of views, the Washington State Ferries from Anacortes, Washington, to the San Juan Islands are a great excursion for visitors to the Pacific Northwest. On a clear day, you can see Mt Baker, some of the North Cascades mountain range and even Mt Rainier to the south of Seattle. While the scenery is beautiful, the real draw to the San Juan Islands is the wildlife in the surrounding waters. Orcas inhabit the waters from mid-April to early October, with the best chance to see them from late May through September.

6. Cruising Ha Long Bay – Quang Ninh Province, Vietnam

If you're headed to Southeast Asia and want to enjoy a few days on the water, make a stop at Ha Long Bay in Vietnam. The bay and its islands are a UNESCO Heritage Site, famous for the bay's jade waters and limestone pillars rising from beneath the water level. You can book two-day/one-night tours from Hanoi, though with more than 1600 islands and islets you could spend much more time in the area. Exploring the natural caves and floating villages by kayak is a great experience.

7. Block Island Ferry – Newport, Rhode Island.

An opportunity to see two of New England's most picturesque harbours, the recently opened Newport-to-Block Island high-speed ferry takes you from downtown Newport to Block Island in about an hour. Perfect for exploring a little bit more of New England for just the day, you can visit either location and catch a late ferry about 5pm back to your origin. Newport was the site of the America's Cup race for many years, while Block Island's free beaches and bluffs are perfect for exploring by bike. It should be noted this high-speed ferry is seasonal and for passengers and bikes only. For vehicles, you'll need to take the ferry from Point Judith.

8. Rhine River Cruises – Throughout Europe

Many assume cruises are for open seas or hopping between islands, but river cruises are a great way to experience European cities as they were meant to be seen – by coming into port. At 1233km long, the Rhine River is perfect for cruising with views that include cliff-top castles, vineyards, and UNESCO heritage sites. Viking River Cruises offers a variety of options from seven-day trips based solely in Germany or an eight-day trip that includes four countries: the Netherlands, Germany, France and Switzerland. For those with serious vacation days saved up, the "European Sojourn" tour from Amsterdam to Bucharest is 23 days long.

9. Ferry from St Thomas to St John – Virgin Islands

Easily accessible for US residents, and particularly affordable in the summer because of hurricane season, the ferry from St Thomas to St John during July to September is recommended by VirtualTourist members. Departing from Red Hook on the far eastern side of St Thomas, the ferry runs to Cruz Bay on St John every hour on the hour starting at 5.30am. The 20-minute ride is incredibly affordable and the crystalline waters are reason alone to make the trip. For only a few dollars one way, visitors to St Thomas can take a day trip to St John where more than two-thirds of the island is a nature preserve with ample hiking and public beaches to explore.

10. Circular Quay to Manly, Australia – Sydney, Australia

And lastly, something closer to home. The ferry ride from Circular Quay to Manly is a tourist destination unto itself for visitors to Sydney. With exceptional views of Sydney Harbour, particularly the Opera House and the Harbour Bridge, multiple VirtualTourist members cited this ride as their favourite ferry ride. While it is often taken just for the views, VirtualTourist members also noted Manly is also a great day trip. The trip from Circular Quay to Manly is only 30 minutes.
