When to Go
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.
Know Before You Go
- You can pick up snacks and supplies in the nearby city of Santa Rosa, just west of the park.
- You can fill your water bottle at the visitor center or at the main parking lot. Wheelchair-accessible features include two picnic areas and a portable restroom.
- Dogs (on leashes) are allowed in developed areas, but are not allowed on trails or in the backcountry.
- Camping is not allowed at Trione-Annadel State Park. If you're looking to spend the night in the area, look into booking a site at Sugarloaf Ridge State Park, just up the road.
