Mafra National Palace, a UNESCO World Heritage site in Portugal, offers a grand exploration of royal history, art, and architecture. Visitors can easily navigate the vast complex independently, though guided tours or audio guides are highly recommended to fully appreciate its significance, including the magnificent library, royal apartments, and basilica with its carillons. The palace is generally accessible, though some sections may have stairs; check ahead for specific accessibility needs. It operates year-round, typically with reduced hours or closures on major holidays, and is less crowded during the off-peak season (winter). Expect an entrance fee of approximately €6-€12 per adult, with special exhibitions or private tours potentially incurring additional costs. A typical visit can last between 2 to 4 hours to thoroughly explore its main attractions. It's conveniently located about 40km from Lisbon and accessible by public bus, making it a great day trip.
