Clettraval consists of an unusually long five-compartment chamber facing E and a straight facade of fallen stones running N/S (best preserved in the S). An Iron Age wheel house, not very well preserved, has been built in the W end of the cairn. It was excavated in 1934 (see Link).
The views from here are splendid - even on a cloudy day. The cairn sits on he 100m contour and, to the S, are the low-lying Lochs Bhaghasaraidh and Steaphain.
Access is very easy. Drive up the metalled military road which runs E from the crossroads at NF718722 until you reach the first radio mast where there is parking. The cairn can be seen in the field opposite.
