Dun Beag Broch
There are about 50 brochs on Skye but Dun Beag is a good example and fairly easy to find, park at and access. Brochs date back some 2000-2500 years so being able to see an example this good is an opportunity not to be missed. It can be found on the Dunvegan to Sligachan road and is worth looking out for if you are in the area to see Talisker Distillery or the Fairy Pools for instance.
It has a small car park and can be seen from the road and it’s an easy walk up the hill to it. Probably best mind you to wear good walking shoes as it can be a bit muddy at times. There is a brilliant view from the Broch itself.
