A vast gravel desert plain covers most of central Oman, with mountain ranges along the north (Al Hajar Mountains) and southeast coast, where the country's main cities are also located: the capital city Muscat, Sohar and Sur in the north, and Salalah in the south.
Coast of Sur, Oman.
Oman's climate is hot and dry in the interior and humid along the coast. During past epochs Oman was covered by ocean. Fossilized shells exist in great numbers in areas of the desert away from the modern coastline.
The peninsula of Musandam (Musandem), which has a strategic location on the Strait of Hormuz, is separated from the rest of Oman by the United Arab Emirates and is thus an exclave. The series of small towns known collectively as Dibba are the gateway to the Musandam peninsula on land and the fishing villages of Musandam by sea. Boats may be hired at Khasab for trips into the Musandam peninsula by sea.
Oman has another exclave, inside UAE territory, known as Madha. It is located halfway between the Musandam Peninsula and the rest of Oman. Belonging to Musandam governorate, it covers approximately 75 km2 (29 sq mi). The boundary was settled in 1969. The north-east corner of Madha is closest to the Fujairah road, barely 10 m (32.8 ft) away. Within the exclave is a UAE enclave called Nahwa, belonging to the Emirate of Sharjah. It is about 8 km (5 mi) on a dirt track west of the town of New Madha. It consists of about forty houses with its own clinic and telephone exchange.

It was named Isle de Palmes by explorer Lazare Picault in 1744. During that time it was used as a hideaway by pirates and Arab merchants. In 1768 it was renamed Praslin in honor of French diplomat César Gabriel de Choiseul, duc de Praslin.
Praslin is known as a tourist destination with several hotels and resorts, as well as a number of beaches such as Anse Lazio and Anse Georgette. It also has substantial tracts of tropical forests with birds such as the endemic Seychelles Bulbul and the Seychelles Black Parrot. The beautiful Vallée de Mai Nature Preserve is known for the unique coco de mer and vanilla orchids. It has been reported that General Charles George Gordon of Khartoum (1833-1885) was convinced that Vallée de Mai was the Biblical "Garden of Eden".
Praslin is home to Praslin Island Airport, while surrounding islands include Curieuse Island, La Digue, Cousin Island, Cousine Island and Aride Island. There are also a few near offshore islets including Round Island (.193 km²) and Chauve Souris (.007 km²); both of which have hotel accommodations.
