Altinkum and Didim are located in Aydın Province between the city of İzmir and the resort Bodrum, about a 90-minute car ride either direction.

The Greek holiday island Kos is an hour's boat ride away and Samos, Rhodes and Kusadasi are also in range. The region has developed from a string of small rural fishing villages into a tourist area. Altınkum and Didim were formerly two separate towns, but have grown together with a combined population of approximately 35,000 permanent residents, including about 5000 foreigners, mostly British with some Germans.

Altinkum, or “golden sands”, is the beach and promenade area within the town of Didim. Visitors are predominantly Turkish or British but over recent years tourists from countries such as Hungary, Bulgaria and Romania have been visiting in increasing numbers, mostly families and the older generation. Set on a sandy bay, the resort is relaxed and informal. There are three beaches within easy reach, and all have been awarded the Blue Flag Award.[citation needed] With 55 km (34 miles) of coastline in the immediate area, there are many beaches to explore, including eleven that have been awarded a Blue Flag classification.

The Main (or First) beach in front of the resort is a long wide stretch of sand with sunbathing and water sports. Sun beds and umbrellas are available for rent. Boat trips that tour the nearby coastline depart from the main harbour, serving lunch and afternoon tea on board. Along the length of the beach are cafes, bars and restaurants.

The Second beach area is just to the east of Main beach and Third Beach is to the west. Just beyond Third beach is Didim marina, currently one of the largest in Turkey which opened in September 2009 and has space for 1200 boats.[1] There are café bars and restaurants within the marina.
