Estrada Nacional 103
EN 103Braga to Chaves
Widely called Portugal’s best road, 84 miles Braga to Chaves.
Ask Portuguese drivers for the best road in the country and the EN103 comes up again and again: eighty-odd miles across the top of the land from Braga to the spa town of Chaves, following the Cávado valley east in fast, open sweepers before swinging north into the Barroso highlands and tightening into proper mountain twisties. It strings together a chain of reservoirs, skirts the southern edge of the Peneda-Gerês national park, and crosses the empty Barroso plateau where long-horned cattle graze the open range. Snow can dust the high sections around Montalegre in winter, and the open sweepers tempt overtaking, so read the closing speeds. A genuinely great day’s drive that almost no one outside Portugal knows.
