This hike has an amazing variety of sites and smells including strange geologic formations, frothy streambeds, tar pits and many different plant communities. The Tataviam Indians used the naturally occurring asphalt for healing purposes and to seal their basketry. At about the 0.9 mile you will encounter a slot like canyon called the Narrows which contains layers of nearly vertical rock formations. After the passage through the narrows stay left, then after another 200 yards stay left again and climb the switchbacks to the left that is called the Towsley Canyon Loop Trail. Topping out at 2450 feet, the trail begins a steep winding descent and includes breathtaking views of lush hillsides and canyons as it heads into Wiley Canyon. Joining a dirt road turn left and head down the canyon. After almost a mile of hiking take the Canyon View Loop Trail to the left which traverses over a summit and takes you back down to Ed Davis Park by the ranger station.
