To the north of the county lies Conca de Barberà, to the northeast lies Anoia, to the east and southeast lie Alt Penedès and Baix Penedès, to the south lies Tarragonès and to the southwest and west lies Baix Camp.[1] Alt Camp has an area of 544.69 square kilometres (210.31 sq mi) and the capital of the county is Valls.
The county is divided into two main topographical areas. The northeastern part is mountainous and is in the Catalan Pre-Coastal Range while the southwestern part is a lowland plain in the Catalan Coastal Depression.[1] The lowland plains of Alt Camp are predominantly used for agriculture.[2] In the valley of the River Gaia, cherries, vines, olives and almonds are grown, and on irrigated land, vegetables, hazelnuts and various fruit trees. The municipality of Bràfim in this valley has a small industrial area.[3] The mountain slopes are covered in maquis, an evergreen Mediterranean scrub with bushes and small trees, including many aromatic shrubs.[4] The olives and grapevines that used to grow on terraces there have been abandoned. Among the scrub there are patches of poplar, elm, white pine, Portuguese oak and holm oak. Frequent wildfires prevent the establishment of permanent forests.[2]
