The city of Abu Dhabi is on the northeastern part of the Persian Gulf in the Arabian Peninsula. It is on an island less than 250 metres (820 ft) from the mainland and is joined to the mainland by the Maqta and Mussafah Bridges. A third, Sheikh Zayed Bridge, designed by Zaha Hadid, opened in late 2010. Abu Dhabi Island is also connected to Saadiyat Island by a five-lane motorway bridge. Al-Mafraq bridge connects the city to Reem Island and was completed in early 2011. This is a multilayer interchange bridge and it has 27 lanes which allow roughly 25,000 automobiles to move per hour. There are three major bridges of the project, the largest has eight lanes, four leaving Abu Dhabi city and four coming in.

Land cultivation and irrigation for agriculture and forestation over the past decade has increased the size of “green” areas in the emirate to about 5% of the total land area, including parks and roadside plantations. About 1.2% of the total land area is used for agriculture. A small part of the land area is covered by mountains, containing several caves. The coastal area contains pockets of wetland and mangrove colonies.

Abu Dhabi also has dozens of islands, mostly small and uninhabited, some of which have been designated as sanctuaries for wildlife. About 1.2% of the total land area is used for agriculture.

The oasis city of Al Ain, about 150 km away, bordering Oman, regularly records the highest summer temperatures in the country; however, the dry desert air and cooler evenings make it a traditional retreat from the intense summer heat and year-round humidity of the capital city.
