Bay Area Rides
Bay Area Rides is a website of (mostly) mountain bike ride descriptions around the San Francisco Bay Area. The site uses Google Maps to display the locations of all rides and to show detailed ride routes.
Users of Bay Area Rides can browse for rides via a Google Map showing all the trails or search by specific bay area. Once you select an individual bike trail you will be taken to a dedicated page with a Google Map of the route, an elevation chart and a detailed description of the ride's length and difficulty.
Users of Bay Area Rides can download the GPX track for each bike trail.
