Hi John!
Courses in Spain.. where to start... there are many courses in Spain!
The most famous is Valderrama in The Costa del Sol, but there are many great courses all over the country.
There are great golf courses in the North of Spain, for example, "Real Club de Golf de la Coruña", "Pedreña", and many others.. there are also great golf courses in Madrid like, "Club de golf Villa de Madrid" and in Barcelona (Catalonia), like "Real Club de golf El Prat".
But also in the South, In la Rioja (winery regions).. and the islands! "Canary Islands" and " Balearic Islands", specially in Palma de Mallorca.
Well, maybe is too much information!. If you tell me which part of Spain you would like to visit, I will recomend you the best golf courses in the area.
