TripAdvisor is launching a new partnership with UNESCO to solicit opinions and feedback on nearly 900 World Heritage sites across the globe.
Many of UNESCO's World Heritage designations — Ecuador's Galapagos Islands, Arizona's Grand Canyon National Park, and Venice, Italy, among them are no strangers to visitor scrutiny. But others, from Southern Illinois Cahokia Mounds archaeological site to Australia's Lord Howe Island Group, aren't as well-known. Using customized review forms, travelers can submit comments on the condition of the sites and find out more on how to protect them.
