A thin Atlantic mist lifts as the van slips out of Lisbon, hugging the Estoril coast where palms and pastel villas lean toward the sea. Windows down, you taste salt and roast coffee; the road unspools with cliff-top views, fishermen’s nets, and the occasional flash of a white-sailed yacht. By mid-morning the Moorish ramparts and candy-colored turrets of Pena Palace appear like a painted dream above the pines—your day unfolds as a sequence of dramatic viewpoints: Cascais’ sheltered bay, the roar at Boca do Inferno, the wind-buffed promontory of Cabo da Roca, and Sintra’s cobbled lanes offering custard pastries called travesseiros.
