Step 0 We started our journey on the EN2 (National Road nº 2) in the city of Chaves. Since we lived sensibly in the middle of the country and had to ride to one of the "tips", it seemed logical to go to Chaves, where the km 0 is situated. we just started from the beginning! We took advantage of the family home in the city of Coimbra to make the trip lighter, as it situated at half way to Chaves. After a meal at a cousins' house, and to catch up with the talk, the night recharged our batteries for the trip to Chaves, next morning. We arrived in the city of Chaves around 2:00 p.m. and we were anxious to go explore the territory. Chaves, located in the region of Alto Tâmega, near to northern Spain border, is the second largest city in the district of Vila Real. Inhabited since the Palaeolithic, it presents/displays diverse marks of the different cultures that passed here, nevertheless the strongest, are of the Roman civilization. Aquae Flaviae, so denominated in those times, exhibits diverse constructions of that time, like the emblematic Bridge of Trajano or the hot spas. Even today, the hot springs of Chaves play a major role in the city. We had already designated the major landmarks we wanted to visit. So we left the two-wheeled "Suzy" to rest in the hotel and burst through the city streets. None of us knew Chaves (in fact, the north-east of Portugal is a practically new region for us) and we were delighted. Exceeded expectation. From the center, quite lively, with traditional commerce, the tangle of streets with the typical coloured balconies, the castle, or the riverside area, with a very well-preserved leisure park. Chaves really has a lot to offer to visitors. From its history, to the wellness and leisure activities, and of course, its rich gastronomy. Still, we had a general idea of the city and to experience some of the obligatory activities: walk across the Roman bridge, eat a cake of Chaves (cheap and delicious) in the Maria bakery and drink a glass of thermal water. The water runs freely from a fountain in the middle of a square next to the hot springs. At more than 70ºC and has a characteristic... smell... But it has a reputation for being miraculous, as we were there we saw several persons go there to fill their glasses and bottles with the thermal water! The afternoon passed quickly and it was time for dinner. Although the fame and offer of catering were a lot, we ended up eating near our accommodation, which was a little way out of the center. The night was cold and we needed to rest to get up early. We had 3 days to do a total of 738 km, travelling the country from top to bottom. The next day, we would leave Km 0, to go through the first leg of our route along the old Royal Road, the National Road nº 2.
