Yes, Indian citizens generally need a transit visa to leave the airport during a layover in Abu Dhabi in 2026, unless they meet specific exemption criteria. If your layover is longer than 8 hours and you wish to explore the city, you can apply for a 48-hour transit visa (which is often free or has a nominal service fee) or a 96-hour transit visa (approx. AED 50). These must be applied for in advance through your airline, such as Etihad Airways. However, Indian nationals who hold a valid visa or Green Card from the US, UK, or a Schengen country are eligible for a "Visa on Arrival" in the UAE for a stay of up to 14 days, which covers transit needs. If you remain inside the "International Transit Area" of Zayed International Airport and do not clear immigration, no visa is required regardless of your nationality. Always ensure your passport is valid for at least six months and you have a confirmed onward ticket to a third destination to qualify for these transit options.
