The Borson's area contains some of the best moderate and most easily accessible bouldering at Rubidoux. All the problems are located no more than a few yards from the access road that is situated just to the East of the summit cross.
Walk up the access road towards the summit. Close to the summit on the East side you'll see the obvious bridge and tower. This is located at the north end of the area.
