Breakfast at the hotel. Al-Hofuf is the main city of Al-Ahsa a region in the Eastern Province of Saudi Arabia. Al-Ahsa is the largest oasis in the world with an area of around 85.4 km2 (33.0 sq. mi), more than 2.5 million palm trees that are fed from a huge underground aquifer which allows agriculture all year round in a region that is otherwise desert. Al-Ahsa also hosts an ancient secret: the Greek geographer Strabo described an ancient Arab kingdom whose capital Gerrha had "fancy tools made out of gold and silver, such as the family gold, right triangles, and their drinking glass, let alone their large homes which have their doors, walls, roofs filled with colours, gold, silver, and holy stones". Until today this site has not been found by archaeologists but one of the candidates is the modern city of Al-Hofuf where we will start our exploration of Al-Ahsa. You will be able to visit the Ibrahim Fort and its mosque, then the Jebel Qarah, a limestone outcrop with caves and canyons and that offers overlooking viewpoint on the huge palm tree cultivations. You can finish this first day in Al-Ahsa at the historical mosque of Jawatha. Overnight in Al-Hofuf.

Breakfast at the hotel. Today you can opt to explore the desert of Al-Ahsa, starting with a stunning viewpoint on one of the lakes located just few kilometres east of Al-Hofuf that reveal the vast water resources of the grounds of Al-Ahsa. This special one is called the Yellow Lake because of the colour of the surrounding dunes. This landscape made of flat grounds rich with water in between dunes is typical of the Eastern Province and is called sabkha. They are particularly impressive 500 kilometres to the south in the vastest sand dune desert in the world called the Rub’ Al-Khali. After the Yellow Lake, if you have opted for a 4x4 car, you can go for a special drive through those dunes and sabkhas. In the afternoon you will drive back for your departure. You can return the car, go to the car rental RETURN parking , and direct yourself to the train station or return the car in Riyadh or Dammam Airports.
