Niagara Falls in Canada topped the list as the most searched for and best-rated adventure holiday destination.
The group of three waterfalls is one of Canada’s top attractions and is usually busiest during the summer.
A trek to Everest Base Camp was the second highest rated adventure holiday in the world but tourists will need to have a minimum level of fitness to attempt it.
The hiking trail is often called ‘the steps to heaven’ and takes in stunning views of glaciers, forest and foothills.
