Dolmen de Kergavat is a chambered tomb that sites largely forgotten next to a busy main road - so close, in fact, that the road dissects the tomb's entrance corridor, which would have approached from the south east. A single chamber is contained within, and a large capstone is supported by a number of smaller stones below.

Despite the unfortunate location, this is a decent little monument and worth stopping to see on the way to or from Carnac.
