During the high season (May to September), the castle usually opens at 9:00 am and closes at 7:00 pm. During the low season (October to April), the castle may close earlier, usually at 5:00 pm.

The Castle of Óbidos in Portugal is primarily a historic structure that is now partially a luxury hotel (Pousada de Óbidos), so while you can view the exterior at any time, access to certain areas is restricted. The medieval walls that surround the town are open 24 hours a day and are free to walk, offering spectacular views of the village. For the "castle experience," the interior of the Pousada is generally reserved for guests, though visitors can often enter the courtyard or dine in the restaurant during standard business hours (typically 12:30 PM to 10:00 PM). If you are visiting for the famous Óbidos Medieval Festival in July, the festival grounds (which include the castle's outer wards) typically open at 5:00 PM on weekdays and 11:00 AM on weekends. For the general historic village, shops and museums usually open around 10:00 AM, making the early morning the best time to beat the "day-tripper" crowds from Lisbon.

The opening hours for Óbidos Castle (Castelo de Óbidos) in Portugal can vary by season. Here are the general guidelines:

• Standard Opening Hours: The castle walls and the historic village are generally accessible to the public 24 hours a day, 7 days a week. You can walk the ramparts and explore the charming streets at any time.
• Pousada do Castelo: The castle itself now functions as a luxury hotel, the Pousada do Castelo de Óbidos. Therefore, the interior courtyards and hotel areas are not freely open to the public for touring unless you are a guest.
• Key Museums & Attractions: For specific attractions within the castle walls, you need to check their individual hours. For example:
  • Municipal Museum (Museu Municipal): Typically open from 9:30 AM to 12:30 PM and 2:00 PM to 5:30 PM (hours can extend in summer). It is often closed on Mondays.
  • St. Mary’s Church (Igreja de Santa Maria): Usually open daily from around 9:30 AM to 7:00 PM.

Important Recommendations:

1. Best Time to Visit: To enjoy the atmosphere without the crowds, early morning or late afternoon is ideal. The walls and streets are beautifully lit at night.
2. Always Verify: Schedules can change, especially on holidays and during the off-season (November - March).
3. Official Source: For the most precise and current information, especially for the museum, it’s best to check the official Óbidos tourism website closer to your visit.

In summary: You can visit the castle walls and the historic town of Óbidos at any time. For specific museums and paid attractions, plan for standard opening hours starting around 9:30 AM.
