It is composed of eight villages: Farcaș, Jgheaburi, Piscu Reghiului, Răiuți, Reghiu, Șindrilari, Ursoaia, and Valea Milcovului.

The commune is located in the central-west part of the county, 32 km (20 mi) from the county seat, Focșani, in a hilly area at the foot of the Curvature Carpathians.

It lies on the banks of the Milcov River, the traditional boundary between Wallachia and Moldavia; the Reghiu River flows into the Milcov in the village Reghiu.

It is crossed by the national road DN2M [ro], which connects it to the south with Andreiașu de Jos and Nereju, and to the east with Mera, Broșteni, Odobești, and Focșani (where it ends in DN2D [ro]).
