Yes, you can leave the airport during a transit in Qatar, provided your layover is at least 5 to 6 hours long. As of 2026, citizens of over 100 countries (including the US, UK, Canada, and most of Europe) can enter Qatar visa-free or obtain a free waiver upon arrival at Hamad International Airport (DOH). If your layover is longer, you can also apply for a 96-hour Transit Visa in advance if you are flying with Qatar Airways. The airport is only about 15-20 minutes from downtown Doha via the clean and efficient Doha Metro, making it very easy to visit the Souq Waqif or the Museum of Islamic Art and return in time for your flight. However, you must pass through immigration and security again upon your return, so it is recommended to only attempt an "exit" if you have a comfortable time cushion. In 2026, Qatar Airways also offers popular "Stopover Packages" that include discounted luxury hotel stays, encouraging travelers to turn a long layover into a 24-hour mini-vacation in the desert.
