Bilkheim lies roughly 13 km northeast of Montabaur in a basin, right on the boundary with Hesse.

In 1345, Bilkheim had its first documentary mention by the nobleman Dietrich von Brambach zu Neurod under the name Bullincheym.

From these grave finds there is support for the belief that there must already have been settlers in the Bilkheim area well over 2,000 years ago.

A railway, since converted into a cycling and hiking path, once linked Bilkheim to the rest of the world as of 1910.

The nearest InterCityExpress stop is the railway station at Montabaur on the Cologne-Frankfurt high-speed rail line.
