Ruthven Barracks sits high on a hilltop with a commanding view of the surrounding area. Free parking and free entry, with a short walk up a hill to the ruins. There is some interpretative signage showing the use of many of the rooms, although it would be nice to have some more detailed plaques for those who wish to learn more about those times. I would suggest 20-30 minutes for the tour and a few more for some photos. Wheelchair /handicap access would be a little tough, however if you can walk 200 yards uphill you can get to the ruins.
