Arrived in Porto yesterday to start Camino coastal Senda Litoral route tomorrow. Picked up metro from airport to Trinidade station in Porto at about Noon. Not very crowded and was super aware (or so I thought). Kept my wallet in zippered pocket of trousers along upper front leg. Just before arriving at Trinidade I noticed my wallet dropped to floor between my feet. Picked it up and put it back in zippered pocket. Later I discovered 150 euros missing. Completely amazed and angry by the situation. Word of caution. From the time your de-plane, put your money, passport, etc in a hidden money belt or waist pouch especially if using public transit. Lesson learned. Hope this helps somebody else!
