This road is popular with Portugal local bikers and has some spectacular viewpoints. It passes through a ski resort area, a shock for Portugal, after rising from the town to a flattish mountain top at 2000 metres. There is an interesting diversion to the right, signposted Manteigas or Valley of the Glacier,which after a mile or so gets to the head of a perfectly formed Glacier Valley.Back on the main route there are some good bends and you can finnish in the village of Seia where you can find a number of good restaurants.
Very nice road. Some traffic, but overall excelent ride. Very good and smooth tarmac, protection, some corners might turn the chill factor on. beware of villages
