From the fire station, follow the path around the grass area adjacent to the station to begin the trail at the north end. The trail climbs steeply, staying primarily on or about the ascending/descending ridge. There's not much shade in route but the chaparral is thick and mature.
At about three quarters of a mile the trail crosses over to the west slope and makes its final pitch to the top ridge. This is the section that can be seen clearly from the city below.
At 1.2 miles you reach the ridge and the Glendora Ridge Motorway, a dirt service road closed to public vehicular traffic. Veer right (east), and take the informal path up the slope to Azusa Peak (2081'), about 0.2 more miles. Enjoy the views of Azusa, Glendora, and the San Gabriel Valley beyond. Return the way you came.
