San Geronimo Ridge Road Professional Review and Guide
"Residential neighborhoods seem to be closing in everywhere, as the squeeze to fit more people into California (the population is expected to top 54 million by 2050) collides with the needs of people to recreate in clean, green open spaces. Marin County is dotted with open spaces, parcels of land where forward-thinking people decided no development would take place. These would instead be left as places where people could ride mountain bikes, stroll with their dogs, or even get out on horseback. The Gary Giacomini Open Space Preserve is one such area—of many— that surrounds the hip town of Fairfax. Here, you’ll gain about 700 feet in elevation for a nice little workout and spectacular views from atop San Geronimo Ridge."
