The City Skyline Challenge is your opportunity to see what you are made of by rappelling from the roof of a skyscraper in downtown San Francisco.


By volunteering as an individual or a corporate group you will be a part of this energetic and high-profile event while also providing a great service to Outward Bound California.


Our sponsors are an important element of this exciting event, and we would like to appreciate them for their support and commitment to communities in the Bay Area and throughout California.

City Skyline Challenge – Save the Date August 18th and 19th, 2017

Experience this high rise event from downtown San Francisco! Your courage in participating or supporting the City Skyline Challenge creates opportunities for young people to be challenged outdoors. Outward Bound California operates from a basecamp in the High Sierra near iconic Yosemite National Park, in the extreme beauty of Joshua Tree, and in the diverse urban center that is the San Francisco Bay Area. The City Skyline Challenge is a fundraiser to get more students of all ages outdoors to learn important life skills like leadership, a desire to serve the community, and confidence.
