September is prime time in Napa Valley. From our perspective anytime is a good time to be in the Valley, but right now the grapes are being harvested and the weather is perfect. This September we have a couple of Impresario travellers smart enough to take advantage of this great time of year. One of the trips is staying at the wonderful Calistoga Ranch, recently ranked in the top five in the world by Travel + Leisure's 2017 World's Best awards. The ranch is tucked into a private canyon in the Upper Valley on a 157-acre property marked by ancient oaks, majestic hills, a rock-hewn stream and private lake. This is the way we would suggest doing it!
