Practical Tips for Visiting Portugal’s Castles 

Plan your castle visit – particularly if you’re visiting Sintra. I’m a huge fan of guided tours and recommend taking one if possible. Not only to make logistics easier, but guided tours will help you understand the castle’s history and architecture better.

Wear comfortable shoes, as some of these castles of Portugal will involve walking uphill and navigating uneven terrain.

These castles are a history trove; some are UNESCO World Heritage Sites. As such, it’s essential to respect the castles’ rules and regulations, which may include restrictions on photography or touching artefacts.
