Outside of Bodrum town, the Bodrum Peninsula is home to several beaches, which get crammed full of sunbathers soaking up the heat during the summer months.
The towns of Ortakent (with two strips of sand: Fink beach and Stone beach), Bitez, and Turgetreis all have good beaches on offer, but there are plenty more to search out if you have the time.
The entire peninsula is popular with both domestic and European tourists, so don't expect to find an isolated patch of sand.
