Our guide was Tammy and she was delightful. We really enjoyed this tour. We were 2 couples from San Francisco mid to late 60s. Walking is easy. Wonderful places to visit, great food, wine, fabulous tea experience, desert, some history of Healdsburg added to the mix plus, we met lovely people along the way. Our group included ages of 20s, 30s, 60s, & 70s. Everyone seemed to loved it. Highly recommend.
