Warmup Loop (1.5 miles): From the Staging Area at the very end of Bollinger Canyon Road, follow Bollinger Canyon Creek Trail going north (0.8 miles + 0.7 miles) to return to the Staging Area. Half of the loop is in the open, amid green rolling hills. Half of the loop is adjacent to a creek and is shaded by trees. The warmup loop is helpful for preparing ourselves for the steep climb that lies ahead.

- Starting from the Staging Area, Rocky Ridge View Trail climbs up 900 ft in about one mile, making it one of the steepest trails in the bay area.
