Take the track to the W signposted to the cemetery off the B842 about 2.5 miles N of the Carradale junction. This is easily driveable until the signpost to the L for the “Toothie Stane” after which it becomes a little rougher. You may wish to park at the sign.
The site is a Clyde chambered cairn excavated in the early 50s. The main stones of the chamber and the two portal stones are visible. The N portal is nearly 3m high and is known as Carragh an Talaidh (Pillar of the Soothing) or the Toothie Stane- see Folklore.
