Ardtreck Point offers an interesting walk of under 3 kilometres, taking in a fairly well preserved dun and some good views over Loch Bracadale. The going is rough in places, and there are no clear paths.
Beginning from near the end of the Ardtreck road at NG338354, follow the track that runs north past a couple of houses. Just before it reaches a gate, leave the track by turning left, where you will find a pedestrian gate opening onto a patch of boggy moorland. From there it's just a case of following whichever sheep track you choose, always heading north-west, until you reach Dun Ardtreck. The dun is of solid construction, with walls almost 3m thick. In the walls are passageways and stairs, still clearly visible. As with most duns on Skye, it sits in a very easily defended position on the cliff top.
Beyond the dun, sheep tracks continue above the cliffs of the west side of the peninsula. Following these will take you to the lighthouse at the point itself. Even better views can be had by cutting north-east to reach the top of the inland crags at NG336362. From there, perched above the lighthouse, you will have a panorama of Oronsay, Ullinish and the meeting of lochs Bracadale, Harport and Beag. A good spot for a picnic on a clear day.
