While a lot of areas are off limits now because of the fires, there are some nice areas. I do a lot of riding in the Cleveland national Forest - up Silverado canyon and all the way to Lake Elsinore. If you cross Highway 74 at Elsinore there is a big offroad park and the trail also carries on all the way to Temecula.
I found a book at AAA called Back Country Adventures which gives great detail about many trails in SoCal. it has been a great resource. Another one that can be useful is www.dirtopia.com
. This is a Wiki site and while some of the info is a bit sparse it does at least tell you where trails are.
