"The SF 100". The ultimate peak challenge for the San Francisco Bay Area. Includes 100 publicly-accessible peaks, from popular, well-known hikes to obscure gems where you'll often have the trail to yourself. An incredible diversity of protected lands ring the Bay Area and this challenge will expose you to the region's many secrets. That it's even possible for motivated adventurers to miraculously find solitude in nature away from the over 7 million people living here is a testament to the work of many who succeeded in protecting these vast lands. Get out there and explore the full reaches of what the late Galen Rowell called "Bay Area Wild". This challenge includes most peaks from the Bay Area Classic Peak Challenge, the Marin 25 Peak Challenge, and the San Francisco 7 Peak Challenge, plus many others.
