Skyline is a fantastic ride, full of beautiful Santa Ana mountain scenery that begins in Corona and ends at Beek’s point. It is a fire road that climbs and climbs, but is full of singletrack diversions that you can ride all the way down. Some of the singletrack can be a bit steep and rutted so use extra caution when coming down. Or you can come back down the same way (fore road), which is also a fast and fun descent. At one point, Skyline was accessible to motor vehicles, but due to drivers going over the mountain, it has been closed off to the public. You can see the aftermath of the accidents, as some vehicles are visible on the side of the mountains. Still, County work vehicles are permitted so be on the lookout and use caution as you ascend or descend Skyline.
