Armstrong Redwoods State Natural Reserve

Armstrong Redwoods State Natural Reserve is a protected area in Sonoma County about 2 miles (3 km) north of Guerneville, with dense stands of coastal redwood trees that can reach heights above 300 feet (90 m). Between the thick trunks run several level paths and a wider forest road leading deeper into the wooded valley.

Colonel James Armstrong purchased the land in the 1870s to protect the trees from widespread logging that was reducing coastal forests at the time. The State of California later acquired the area from the family and turned it into a public reserve.

Local people often visit the trails early in the morning when the tall trees create a special light and a calm setting. Families from nearby towns come here on weekends to spend time among the old trees and show children the forest.

The main trails are wide and level, making them accessible for wheelchairs and suitable for people who prefer to avoid steep climbs. On cooler days or early in the morning, the shade under the tall trees makes it noticeably colder, so bringing a jacket is a good idea.

Some of the oldest trees in the reserve are over 1400 years old and started growing long before the first European settlers arrived in California. Their bark can be more than 12 inches (30 cm) thick in places and protects the trunks from fire and pests.
