Staying in Healdbsburg for 3 nights end of July. What wine tours would you recommend? Something more private than a bus full of people is more our style. There is a wine carriage ride that has great reviews and sounds romantic--any thoughts? Cost is an issue as I don't want to spend more than 400 for 2 of us but we would like someone that has knowledge so we use our time wisely and get the most of out of our time there! thanks for everyone's help!
