Kas is on a hill running down to the sea. The district has a typical Mediterranean climate of hot, dry summers and warm, wet winters, which allows the growth of oranges, lemons and bananas. The lowland areas are also planted with cut flowers and a variety of fruits and vegetables, many are grown all year round under glass. The hillsides produce honey, and almonds, while at high altitudes there are extensive pine forests. The weather is drier at high altitudes. Although agriculture is still important, tourism is the main source of income in the district, which has many hotels and guest houses.

About 2 km (1 mi) off shore from Kas is the Greek island of Kastelórizo (in Turkish Meis Adası) to/from which Turkish vessels ferry from time to time.
