Why a Week Works Well
Portugal's key heritage sites — Lisbon, Tomar, Belmonte, Trancoso and Castelo de Vide — are spread across roughly 400 kilometres, close enough to link without long transfers but distant enough to reward at least a week. Seven days allows two nights in Lisbon, a night in the Serra da Estrela, and time in the Douro or Alentejo without rushing any single stop.
