Flagship guide · Saudi Arabia
Al-Ahsa is the largest oasis on Earth, over two and a half million date palms rising out of desert that stretches unbroken in every direction. UNESCO recognised the whole thing in 2018, springs, canals, gardens and all.
The oasis isn't the only strange, beautiful thing here. Al-Qarah Mountain has been hollowed by wind into mushroom-shaped caves you can walk straight into, the Al-Qaisariya Souq has been trading since 1822 under the same covered alleys, and Al Asfar Lake sits naturally, unmistakably yellow, ringed by sand dunes on every side.
This is a first glimpse of what your time in Al-Ahsa could hold. Tell us your dates and who's travelling, and we'll shape the rest around you.
