This 11K loop will cover you with some of best views in the park.
Sunol Wilderness is a great weekend escape for people at San Francisco bay area. This 11K loop starts with steep terrain to Flag Hill and continues climbing slowly to the highest point (Cerro Estate Overlook). At the overlook, you'll have great view to the nearby Calaveras reservoir. Along the way, you also have opportunity to see Bald Eagle if you're are really lucky. Cattle are often encountered on the trail. After the highest point you descend gradually back to the trailhead. If warm, plan appropriately, there is little cover along the majority of the trail. The trailhead is located at the bridge near the visitor center.
