I won't go all the way to Gorman from the Redlands area, but I've been there (Hungry Valley SVRA) and can tell you it's fairly noob-friendly. A lot of the trails are very soft, though so it's like riding in sand. The trails up through the hills are pretty cool though. They're marked according to difficulty, so just pay attention to that and you'll be fine. If I was going to go to Gorman, though, I would bring my ATV. But at 12 mpg and traffic, and a 2+ hour drive each way, I'll have to pass. :)
