Even on a tight schedule, Sintra Day-Trip earns the hours.
Allow Full day.
Genuinely magical — a forested microclimate dotted with Romantic palaces, the kind of place you can't believe is a day-trip. The honest catch: it is mobbed, the village and shuttle buses choke in summer, and trying to cram Pena, Regaleira and more into one day is a stressful, queue-filled forced march. Pre-book, go early, pick two sites not five.
