Bishop Peak is the tallest of the Nine Sisters, the picturesque volcanic Morros stretching across San Luis Obispo. The iconic mountain has a rocky crown shaped like a bishop’s miter, which provides panoramic views over the city and nearby peaks. The single-track trail to the 1,559-foot summit is demanding and rewarding – a truly excellent hike. From the trailhead at the top of Highland Drive to the summit of Bishop Peak is 3.5 miles round trip with 950 feet of elevation gain.
