My husband and I have 4 days in Barcelona and 4 days in Madrid and were thinking of hiring a car and driving from barcelona to La Rioja and stay there for say 2 nights and explore the regions - wine tasting and walking and trying resturants, before driving to Madrid. Is this recommended? is it a nice drive from barcelona, and then to madrid? Are the wineries welcoming and can we sample wines there? All advice would be very welcome.
