My boyfriend and I did a small group Sonoma Valley wine tour with Edge of the World and it was seriously awesome. Marc was knowledgeable, funny, entertaining - an all around fantastic guide. The ride was comfortable, the wine was delicious (all from local, small family-owned wineries too!), and the tour was well-paced. We’ll be booking with Edge of the World tours next time we’re in SF. If you’re looking for a great way to see the Bay Area and drink great wine, this is the way to go!
