Can't add much to what is already on here. Seefin is a very handy and direct walk from just south of the entrance to Kilbride Firing Range where the range meets the forest. A flagpole at the entrance indicates whether firing is taking place or not. From the road, it's simply a case of following the well beaten track all the way to the lairge summit cairn/passage-tomb which is something of a mini-Newgrange. Walked as the first top on the Kilbride circuit but I'd suggest leaving it until last on this circuit as it definitely is the most interesting of the passage tombs.
