What park has a rough bicycle path in Los Angeles best for adventurous type of bikers
The path at West Fork, San Gabriel contains a rough part but it's quite doable. The path is not exclusively for mountain bikers for there are a lot of paved path that contains a lot of great scenery. But the path along its western ends is rough and difficult for regular bikers. You well surely enjoy the Los Angeles National Forest in taking this route.

If you should decide to try out these routes make sure that you can handle the rough path and make sure that your bike can also handle it. Check every piece of equipment you are about to use before taking the path. And make sure that you bring a first aid kit just in case something will happen while taking the rough path.
