Legolas never once mentioned going that way, which is a little surprising. He would have known where his kindred were hidden as ambushers in Mirkwood, so they may well have received an escort for much of the journey once they went in. Though the Eye of Sauron may well have been fixed on and near to Dol Guldur.
