Tourist attractions around the world are always expected to be busy, especially when travelling during the summer holidays.
As a part of every holidaymakers bucket-list, it can be hard to avoid some of the popular tourist spots.
However, the worst offenders for the longest queues have recently been revealed.
The worst is much closer to home than many may realise.
The London Eye emerged as the worst tourist attraction for queues, with queues of two and a half hours long, according to new research by TripAdvisor.
However the famous Catacombs in Paris, whilst usually only having a two-hour queue, can have a whopping four-hour wait during peak summer months.
Also in Paris, the Eiffel Tower came in at two hours, the same time as the Colosseum in Rome and the Sistine Chapel in Rome.
Other long waits including the Tower of London, Van Gogh Museum in Amsterdam and the Empire State Building in New York of an hour and a half.
The tourist attraction that came out the best on the list was the Notre Dame Cathedral in Paris, with just an hour wait to go in.
However, if choosing to go up the tower, it then extends to two hours.
Tourists can book with TripAdvisor on tours where they can skip the queues if attempting to do many of the attractions in one day.
Brooke Ferencsik, senior director of communications for TripAdvisor, “By booking skip the line tours on TripAdvisor, travellers can spend more of their time viewing amazing attractions around the world rather than the back of someone’s head in line.”
