Exactly
As the previous posts mentioned, you can't get close enough to touch the sign. There are several trails; wisdom tree, the Griffith observatory, or the Griffith Park tennis courts. In my opinion the trail from the observatory is the easiest, wisdom tree the hardest.
You can get both in front of it and behind it, but the front view is further away than the view from behind. I've done both; the front makes for a great picture, and behind is a cool view of the city. There are signs along the trail for both.
There is no Direct path to the sign but you can hike behind it .. via the wisdom tree Trail.
You can get to an area behind it
No...its restricted area...
