Sintra is a magical UNESCO-protected town nestled in the hills 30 km west of Lisbon — one of the most popular day trips from the Portuguese capital, which often leads visitors to stay longer than planned. Its distinctive microclimate brings unpredictable weather and frequent mists that heighten the mysterious atmosphere — fairy-tale palaces, a medieval Moorish castle, and romantic hilltop villas are steeped in legends and ghost stories. Sintra inspired Portuguese writers of the Romantic period (Eça de Queirós, Almeida Garrett), as well as Lord Byron, who immortalized it in 'Childe Harold's Pilgrimage' in 1812. The most beautiful palaces — Pena, Regaleira, Nacional — are set along steep winding roads, making a combination of bus, walking, and taxi the best way to explore.
