The 17 mile trail that crosses San Francisco from the Bay in the South East corner of the City to Land's End in its' North West Corner,  cuts right through the heart of our 49 square miles of natural beauty.  It traverses urban gardens, solid neighborhoods, the Presidio, Golden Gate Park and leads you to the dramatic cliffs overlooking the Pacific Ocean. The brainchild of Bob Siegel a one time Peace Corps volunteer and college professor, the Crosstown Trail has become a top attraction during Covid gym shutdowns. It's also becoming an inspiration for cities as far afield as New York and Glasgow to create similar trails.
