This Saturday, take in a different view of the city (although your best friend's rooftop deck isn't so bad either...) and trek San Francisco's 13-mile Peak to Peak walk. Peak 2 Peak (unlike B2B) will give you an incredible perspective of the city's highest peaks and allow you to explore hidden nooks, crannies, and city secrets you never knew existed. And not only will this adventure be beautiful and a chance for you to get out, but Walk SF will be providing lunch, snacks, and a year-long membership to their organization.

Invite your friends on Facebook and Twitter to trek San Francisco with you, and get out in the city this Saturday. Meet at 24th and Mission, and the walk will end at Land's End in the late afternoon.
