For those familiar with the Arastradero Preserve, the first thing you may think of regarding the area is its hills of ornate, golden grass. However, this is not all it has to offer. When you traverse further down through the path, you will reach the Acorn trail. Aptly named, the Acorn trail is known for its plethora of trees, something notably missing in other parts of the trail. During the fall season, the landscape is filled with russet foliage and tumbling fir-cones.
