Hendy Woods State Park, less than three hours from the bustling San Francisco Bay Area, protects two magnificent ancient redwood forests. Eighty-acre Big Hendy and twenty-acre Little Hendy groves offer peaceful surroundings and serenity broken only by the sounds of nature. The beautiful Navarro River plays a soothing counterpoint to the distant tapping of woodpeckers and the gentle wind in the trees. Hendy Woods is located in one of the most scenic areas of southwestern Mendocino County. Located inland, about eight miles northwest of Boonville in the middle of the Anderson Valley, the park is warmer and less foggy than redwood parks along the coast. High and low temperatures between November and March can range from the high 50s to the low 30s at night. From April through October, daytime temperatures range from the low 60s to low 100s, and from the low 40s to the low 50s at night. Layered clothing is recommended year round.
While your visiting the wine country (and feeling like you need to metabolize some wine off), why would you not stop at Hendy Woods State Park? This loop includes Big Hendy Grove and the Discovery Trail. It's almost as good as Montgomery Woods in the same vicinity. It's grand "coastal" Redwood Trees.
