Castalla (Valencian and Spanish: [kasˈtaʎa]) is a town located in the comarca of L'Alcoià, in the province of Alicante, Spain. Castalla is located in a mountainous area, 35 km from Alicante.

Castalla Castle sits on a hill overlooking the valley and the town is around, at the foot of the hill, 680 m above sea level. Castalla La Hoya, whose history is Castalla capital, is a broad valley in the form of T oriented to the southeast and sandwiched between various mountain formations. Castalla occupies the west and southwest of La Hoya which interlock like Maigmó mountains (1296 m), Cati (1260 m) or Argenya (1230 m). The climate of the area can be locked in a mid-mountain Mediterranean climate. The average annual temperature is around 17 degrees. The rains are not abundant, around 400mm per year, but mountain ranges favor the formation of cloudiness and local rainfall, increasing these with altitude. Snowfall is common in winter days of January and February. Communicates with Alicante and Valencia along the A-7.
