My wife and I decided to book Napa Valley Balloons and the companion trip with Platypus wine tours afterwards. Like many reviewers have mentioned, we were not able to launch in Napa Valley because of the weather conditions. However, we were pleased that the alternate location in Yolo was available for us to experience this amazing ride!
For us, the question was not where we flying over, but just the sheer fact that we were flying! Our pilot, Bob, was a wealth of knowledge and experience, and at no time did we feel uneasy about the navigation.
The brunch afterwards was very delicious ("best bacon anywhere per Bob") and we had to agree. The expectations were explained fully once we arrived, and we were not charged until the ride concluded. Whether you see beautiful farm fields or vineyards, the mountains are there either way. We got to watch a crop duster at work and see the beauty of this part of the country.
We were completely pleased and encourage others to not let the specific view of the day dampen the overall experience. It's a 'bucket list' time that you won't want to miss.
