When I click on the directions from Santa Rosa told me 7hrs and 52 minutes. Yes took me that long. But found out from other family members took them 5hrs from Santa Rosa. Google maps only show you two different directions. After finding out I took the wrong route to the campsite. The faster route is going through Clearlake 29 and then to Hwy 20 E. Then to Hwy 5 North to Redding to Shasta County line. Take exit for the Lake Shasta campground to Hertz Bay Campground. This will take you about 4 to 5 hrs. Not take the directions from google mentioned on the website. And coming back to Santa Rosa. Take Highway 5 south until you see Highway 80. Take you to Vacaville to Vallejo exit West to highway 37 or Highway 12 going to Napa to Sonoma County line. This highway will split to either go towards Petaluma or Sonoma town. I would take going towards Petaluma highway 116 west. Then to adobe Road then to Petaluma Road North to Cotati then to Santa Rosa back roads. For anyone that lives in Santa Rosa. And hasn’t visited this campground. Going for the first time. Don’t make this mistake like I did. No showers at the camp site only two toilets. No bathroom sinks and no soap despensors. No mirrors in the bathroom. There was a black bear came to the site at 4am. Got into the food that was on the table. Place the food in the box lockers when not in use. Bring with you a portable shower cover to take showers. Bring solar chargers and solar lights for night time. Very dark at night. Bring extra lights for the two bathrooms. There is no light in the bathroom if you need to go in the middle of the night. Take main pathway to the lake to swim. Don’t take the steep slope hill like we did. Very dangerous can slide and hurt yourself. Safer ti take the driveway pathway down to the boat dock to swim. The large barbecue hanging one is broken. Need to use rope or other type of item to keep it hanging to place your food to cook. Bring a starter to heat the charcoal like I did. Helps light faster. It does get very hot. Bring a hand towel to keep you cool. I brought a couple of them for my family. Fire pit is there. Love using it. Lots of tables. One of the tables is broken. There is only two faucets to use to wash your self and to wash your dishes. Both only cold water. Bring a large bucket to wash your self and a smaller bucket to wash your hands for the bathroom and leave there for use with hand sanitizer and soap. So people can wash the hands in the small bucket of water. And bring a sprayer for the smell.
