Abu Dhabi is located in the central-western UAE on the Persian Gulf, and it is a T-shaped island city. It is the capital of the UAE.
This modern city still maintains a strong Islamic traditional atmosphere, with excellent greenery, earning it the reputation as an oasis in the desert.
Abu Dhabi is more chill, relaxed, and has a stronger vacation vibe than Dubai. If Dubai is about "tourism," then Abu Dhabi is about "unwinding."
