Two hours before sunset (please check sunset time), you will be picked up by car at Sintra's train station. On your way to where this evening walk will start you'll be able to see in the distance Sintra's Castle, Pena Palace, and the forest gradually beginning to surround you. Once you have  arrived in the western part of Sintra's Mountains, your walk will begin. The walk will be about 5 kilometers, spanning around 4 hours, on regular and soft irregular terrain. The effort implied is equivalent to spending a whole afternoon strolling around Sintra, with its various ups and downs. You'll travel under the black arc of the night sky, dotted with a thousand stars, to discover a hidden past that's almost impossible to imagine. Watch the sun falling over the Atlantic Ocean. After sunset you will enter the forest and learn about the wolves, wild boars, and friars who once roamed these paths. Your historian guide will tell you about the religious orders and unusual stories from the area's history.
