The Costa Cálida extends from El Mojon in the north near the province of Alicante, to near the municipality of Aguuilas in the south bordering on the region of Almeria Province.

The northern end of this coastline includes the Mar Menor ("Little Sea"), a coastal saltwater lagoon which at around 170 km2 is Europe's largest. The Mar Menor is separated from the Mediterranean by a 22km-long spit of land called La Manga, on which most of the tourism development for the region has been constructed.

Cartagena and Mazarron are two other important coastal towns in the region.

Golf is a huge pastime for visitors & residents alike with plenty of golf courses to choose from. There are many PGA championship courses such as El Valle which hosted the PGA European Seniors Tour in June 2011, Hacienda del Alamo which is the longest golf course in Spain and of course the famous La Manga Club.  The Costa Calida is second home to many Spanish Property buyers.
