Transported back to the time of Kings and Queens, we were exhilarated to climb up steep stairs to the top of the castle walls. They are walkable all the way around town but no bannisters make very courageous tourists step carefully over crumbly rock and brick. Adventurous and brave we witnessed amazing views of the surrounding lands and the Aqueductos do Óbidos, that carry drinking water to the town from a spring in the mountains 3km away.
