While you can walk in Sintra, it is a physically demanding choice that requires careful planning due to the town's steep, winding hills and the distance between major sites. The walk from the historic town center up to the Moorish Castle and Pena Palace is a steep uphill trek that takes about 45 to 60 minutes and is only recommended for those with good fitness and comfortable shoes. However, walking down from these monuments back into town is a popular and scenic option. For most travelers in 2026, a hybrid approach is best: take a taxi, rideshare (like Uber), or the 434 tourist bus up to the top of the hill, and then walk between the monuments or take the trail down. Notably, as of 2026, private vehicles are restricted from parking near Pena Palace, making pedestrian paths and public shuttles even more central to the experience. Walking is the best way to explore the interior gardens of Quinta da Regaleira, where the famous Initiation Well is located.
