Climb the 5 publicly accessible peaks in the famous 9 Sisters, also known as the 7 Morros, and even more confusingly often called the 7 Sisters(?). This string of volcanic hills stretches from Morro Bay to San Luis Obispo, California. The 5 peaks in this challenge -- Black Hill, Cerro Cabrillo, Bishop Peak, Cerro San Luis Obisbo, and Islay Hill -- all have trails to their summits. Bishop Peak, the highest of the Nine Sisters, is considered a must-do hike in the SLO region. Note that this challenge includes the east summit of Bishop, reached by a short class 3 scramble, not its highest point, a technical summit block.
