We researched dozens of options for Napa tours and we're so thankful that we chose Green Hills! Aloys is extremely knowledgeable about the area, wines, restaurants, everything you could need. 4 of us were picked up at our inn in San Francisco in a very comfortable luxury SUV and he went out of his way to show us so many awesome sights on our way to wine country. He assisted in choosing wineries based on our personal likes and dislikes, as well as helping us choose the perfect place for lunch. By the end of the day we were looking for ways to cancel our larger group tour to Sonoma so that we could have Aloys take us! From beginning to end, the best experience. We will definitely be calling Green Hills back!
