Yes, you can absolutely take an Uber from central Lisbon to Pena Palace in Sintra, and it remains a popular choice for those who want to skip the train. In 2026, a one-way UberX ride typically costs between €35 and €60, though surge pricing during peak tourist hours or summer weekends can push the fare closer to €80 or €100. The drive usually takes 40 to 50 minutes. However, travelers should be aware that Uber drivers are often restricted from driving all the way up the narrow, steep hill to the Palace gates due to local traffic management. They will likely drop you at the Sintra town center or the entrance to the Pena Park, where you may still need to walk or take the dedicated 434 tourist bus or a smaller "tuk-tuk" for the final leg of the ascent to the actual palace entrance.
