Yes, as of 2026, entry to the Castelo de São Jorge is included for free with the Lisboa Card. For many years, the castle was one of the few major attractions that only offered a small discount, but current card benefits now allow for full complimentary admission. This makes the card significantly more valuable, as the castle is one of Lisbon's most visited sites. In addition to the castle, the card provides free access to over 50 other museums and monuments, including the Jerónimos Monastery and the Belém Tower. A major logistical perk is that the Lisboa Card also includes unlimited free travel on all public transport, including the historic yellow trams (like the famous 28), the Metro, and even the trains to Sintra and Cascais. To make the most of your card, it is best to visit the castle in the early morning to avoid the long queues that often form by midday at the entrance gate.
