For those of you who have not been here before, its very easy to find. Head up Arnold dr north from the town of Sonoma. After passing through the Sonoma Development Center, you will cross a bridge, look for parking on the right hand side of the road as the entrance to the park is not far up on the right. A paved walking path heading away from the road. You will most likely see other cars parked there. If you are unsure as to the location, just google "Sonoma Regional Park" its very easy to find. We will take the paved path, then cross over to the trail around Suttonfield lake, then take that path around the lake.
Its an easy 35-45 min hike around the lake... or take some of the trails that go up in the hills.
