Armstrong Redwoods State Natural Reserve
Here's your best opportunity in the western Wine Country to wander amid Sequoia sempervirens, also known as coast redwood trees. The oldest example in this 805-acre state park, the Colonel Armstrong Tree, is thought to be more than 1,400 years old. A half mile from the parking lot, the tree is easily accessible, and you can hike a long way into the forest before things get too hilly. During hot summer days, Armstrong Redwoods's tall trees help the park keep its cool.
