Pena Palace is open daily for visitors. There are fewer tourists around during weekdays than at weekends, making weekdays the best time to visit the palace and its gardens. Also, visit Pena Palace early in the morning or late afternoon due to fewer visitors. You can avoid tours arriving between 10am to 3pm.
July to August is the peak season in Sintra. Pena Palace is also busy during this time, with many tourists covering the palace along with National and Moors palaces between 10am and 4pm. The weather is fantastic and better than hot summers, where walking to the palace and exploring the gardens may feel like a torcher. However, prices are lower during the low season, making it the perfect time for budget-friendly trips
