Head out for a hike in the heart of the California wine country.
Discover the most magical spots to pitch your tent or park your rig on your next Trione-Annadel State Park adventure.























Situated in the Valley of the Moon, on the edge of Santa Rosa, this 5,500-acre state park offers over 40 miles of trails plus seemingly endless fields, a man-made lake, and a pretty marsh. Trione-Annandel also provides a habitat for all sorts of creatures, from aquatic birds to rare California red-legged frogs. Hiking options abound, with a wide variety of routes that range from easy to challenging, and many of the trails are open to mountain bikes and horses. Anglers are welcome to fish for bluegill and largemouth bass at the lake, provided they obtain licenses in advance.
Trione-Annadel State Park is open daily from sunrise to sunset all year round. The weather is at its most pleasant from May through October, when the temperatures are warm and the chance of rain is low. September and October are ideal if you want to be in the area for the annual wine harvest, and the weather this time of year is ideal for hiking, when high temperatures rarely exceed the upper 70s.
