Sitges, situated just south of Barcelona, belongs to the Garraf region and is surrounded by sea and mountains, along 18 km of Mediterranean coast, most of which is made up of beaches. Its Passeig Marítim, or seafront Esplanade, is more than 3 km long, from the Baluard (Bastion), a spectacular natural viewpoint, to the Terramar residential area.
Sitges has a surface area of 43.7 km2, stands at an altitude of 10 meters and lies 35 kilometers south of Barcelona, which is in easy reach by highway, motorway and train. The Barcelona Prat International Airport is just 15 km away.
Sitges’ situation at the southern edge of the Garraf Massif, a calcareous rock mountain range that constitutes a natural barrier, blocks the cold northern winds. This exceptional location makes it possible for the town to enjoy its very own microclimate, with mild summers and winters, an average temperature of 18.7ºC (65.7ºF) and more that 300 sunny days a year.
