Couldn't recommend this trip more, our guide Kim, was super friendly, fun and knowledgeable. We had a small group of 12 of us. We managed to go to 4 different wineries, didn't feel too rushed and got to try a good amount of wine in each location. Plenty of wine was flowing all day, all snacks and lunches provided were delicious. A cheese platter was given mid morning and then a lovely picnic lunch was provided at a beautiful location.
We were staying in San Francisco, and the coach can not pick you up from there, so we had to get the boat Vallejo Ferry port. The directions provided and instructions to get there are super easy too follow. We left San Francisco at 8:15am, and we were back there by 6pm, everything went smoothly.
Thanks Platypus for providing a fun filled day, 100% recommend.
