TripAdvisor has announced it has finalised the acquisition of Viator, a leading resource for researching and booking destination activities around the world.

Viator features more than 20,000 bookable tours and attractions and more than 600,000 reviews, photos and videos submitted by travellers.

“We’re thrilled to add Viator to the TripAdvisor family and to grow in the attractions and activities space,” said Stephen Kaufer, president, TripAdvisor.

“TripAdvisor’s scale combined with Viator’s strong network of global activities and attractions will allow us to help even more travellers plan and have the perfect trip.

“Along with the acquisition of online restaurant booking site lafourchette earlier this summer, we’re eager to leverage these powerful booking assets to provide the most comprehensive travel-planning experience for our global community of millions of travellers, both online and via mobile.”

Viator works with the best local operators to provide travellers with access to tours and activities in popular destinations worldwide.

Bookable in ten languages and in ten currencies, travellers can book online in advance, and in destination via the Viator Tours & Activities App.

In addition to its consumer-direct business, Viator also provides local experiences to more than 3,000 affiliate partners, including some of the world’s top airlines, hotels and travel agencies.

“Now that Viator is officially part of the TripAdvisor family, we’re excited to help even more travellers explore their destination like an insider, powering advance and last-minute access to thousands of amazing travel experiences worldwide,” said Barrie Seidenberg, president of Viator.

“Our teams and goals are highly compatible, and as we move ahead leveraging our shared focus on speed, agility and innovation, we look forward to developing the resources and products travellers need to make every trip unforgettable – anytime they travel, just about everywhere in the world.”

Viator has more than 250 employees who will continue to work at the company’s headquarters in San Francisco and offices in Las Vegas, London and Sydney.

The company will continue to operate under the leadership of Seidenberg.

Viator is TripAdvisor’s fourth acquisition in 2014, following lafourchette, Tripbod, and Vacation Home Rentals.

The purchase price for the transaction is approximately $200 million, subject to adjustment, and will be payable substantially in the form of cash.
