Ávila (Spanish: [ˈaβila] ⓘ) is a province of central-western Spain, in the southern part of the autonomous community of Castile and León.

The northern portion is generally level; the soil is of indifferent quality, strong and marly in a few places, but rocky in all the valleys of the Sierra de Ávila; and the climate alternates from severe cold in winter to extreme heat in summer.

The southern division, however, is one mass of rugged granitic sierras, interspersed with sheltered and well-watered valleys, abounding with rich vegetation.

The ridges which ramify from the Paramera are covered with valuable forests of beeches, oaks and firs, presenting a striking contrast to the bare peaks of the Sierra de Gredos.

Meanwhile, the Adaja, another Douro tributary whose source lies at the cut-off point of the Sierra de Ávila and La Serrota, carries little water in the Summer.
