Guadiaro River Estuary and Torreguadiaro Lagoon are two of the most relevant nature spots in the borough of San Roque. The river estuary is located at the rivermouth, in the heart of Sotogrande Costa. Torreguadiaro Lagoon is situated between Sotogrande Marina and the village of Torreguadiaro. Both nature areas are wetland areas of great importance for many species of birds and excellent points of observation for ornithologists interested in the Strait of Gibraltar as a migratory route between Europe and Africa.
The Arca Mountains, situated north of the Alcaidesa residential area and the A-7 dual carriageway, is one of the Gibraltar Area’s most attractive geological formations. The mountain range covers a 200 hectare surface area of Mediterranean scrubland, with cork oak and pine trees.
San Roque has a collection of listed historical buildings that are the oldest and best preserved in the Campo de Gibraltar area. The most important monuments in the City of Gibraltar in Exile are Saint Mary the Crowned Parish Church, the Governer's Palace and the Bullring.
The Carteia Archeological Site dates from the 7th century BC and includes remains from the Phoenician, Carthaginian, Roman, Visigothic, Byzantine, Moorish and Christian eras. This ancient city was the most important in the Campo de Gibraltar area and became the first Free Latin Colony outside of present-day Italy in 171 BC.
