A green wall across Queensferry Road marks the start of the hike. Beyond the gate, the road descends for another quarter-mile, leaving Brentwood’s affluence for nature’s riches. When the pavement ends, turn right and cross a wide swatch of gravel with a seasonal creek flowing down the center. Concrete mats installed by the Gas Company allow easy travel up the canyon. The dirt and gravel trail heads north on a gentile grade running parallel to and overlapping the small seasonal creek. Yellow posts every few hundred feet serve as a reminder that The Gas Company has a pipeline running through the canyon.
