Start and finish at Faro Airport, with one night in Faro, two in Tavira, two in Lagos and one in Silves. This keeps the region’s different landscapes in the same week: Ria Formosa’s island beaches in the east, the rock arches around Lagos, the exposed headlands of Sagres and the wooded Monchique hills. The car connects those places; inside the historic towns, leave it parked and walk. There are three changes of base, a substantial east-to-west motorway crossing and a separate Sagres outing, so this is a touring holiday with beach time rather than a resort stay. April–June or September–October suits the mix of town walks and coast, while ocean conditions still decide whether a boat trip runs. The final Silves night gives the red sandstone castle its own morning before a later flight from Faro.
