Many people believe that only Algarve or Lisbon are nice locations to visit
in Portugal. In fact the interior of Portugal has more history and fun that you can possible imagine...and guess what? Many of those interior locations are less expensive to go in Holidays.
You can discover great Castels of Portugal like " O Castelo de Gimarães"or enjoy the less poluted river in all europe " Rio olô" In Amarante. And because the nature is green and precious in this part of the country you can make many radical sports like kayak, body jumping in " Marão".
If you are a traveller and if you enjoy the unknown and rich historical places you should visit the only part of the world where " vinho verde" is made.
