I suggest 4 places to go, and a great place to stay
Pinhao, an interesting town on the Douro Valley
Casa de Mateus, this famous estate is near Vila Real
Quinta do Panascal, vineyard and port cellar , 12 minutes from Pinhao
Lamego, a beautiful church and spectacular gardens with its grand stairway
Stay at Casa Dos Barros Villa, Sabrosa not far from Pinhao
see the following posts for details.
Another way to explore is take a tour like this, Wine tours
Just north west of Pinhao, between Vila Real and Constantim, are the stunning gardens and villa
This is one of the small independant producers of Port, they grow their own grapes, stomp on them, make the wine, then blend and age.
They are only 12 minutes down river from Pinhao, and tucked in a beautiful small valley.
A little hard to find, but well worth the effort, south west of Pinhao
Located in the town of Sabosa not far from Vila Real or Pinhao, it has been in the family for 300 years, experience true Portuguese hospitality
Where to go and what to do
Look for the i SITE Visitor Centre in Picton and Blenheim
i-SITE Visitor Centres are part of New Zealand’s official nationwide Visitor Information Network.
In Picton it is on the Foreshore, and in Blenheim it is beside the railway station on the main highway through town.
They are your one stop travel shop for everything to see and do and stay in Marlborough. They are a free advice and bookings service, for all accommodation and adventures in Picton, Marlborough Sounds, and the Marlborough regions.
