Tripadvisor

Tripadvisor is best known as a travel review platform, and for sightseeing its value lies in traveller reviews, photos and rankings of attractions, tours and activities in destinations worldwide. Its Things to Do section lets users compare what other visitors thought of museums, landmarks and tours before deciding, and many experiences can be booked through it, fulfilled by Viator, the Tripadvisor-owned tour marketplace. Travellers' Choice awards highlight attractions and experiences that receive consistently strong reviews. It suits planners who want practical tips from other visitors, such as the best times to visit and how long queues tend to be. Reviews are user-generated, so weigh recent reviews more heavily and look for patterns rather than single comments. Check booking terms with the actual tour operator, which may differ between listings.
