The most direct route from where Smithman was seen to this section of the Praia da Luz coastline is past the Dolphin Restaurant (which is opposite Kelly’s Bar where the Smith family had been). However, before getting to the restaurant, Smithman might have turned right up Rus das Salgadeiras. It’s a bit further, but avoids the area around the restaurant and Kelly’s Bar and the greater chance of running into someone.
