Great views into the Russian River estuary. Just before the Bridge on the south side is a store for resupply and food. The small Willow Creek Road before the bridge to the north follows the river's south side with great views and access to trails up the mountain.

Willow Creek Fire Road is perhaps one of the greatest gravel roads for biking in the area. Whether you are looking to rip on a gravel bike or just cruise on your hard tail, this road fits the bill for just about any rider. There are numerous trail and road intersections where you can turn and loop back, or you can just do an out and back from either end. Note that while this is a smooth gravel road, it's completely closed to car traffic, so you'll be the fastest thing on the trail.
