Before 2017, the municipality was located in the Disentis sub-district of the Surselva district (which was, until the end of 2000, the Vorderrhein district). It is the largest of the seven municipalities that make up the Disentis sub-district and is the capital. It consists of the center village of Mustér-Vitg and the neighboring villages of Mompé-Tujetsch, Segnes, Acletta, Funs/Clavaniev, Disla, Cavardiras and Mompé-Medel. Except for the two Mompé villages, all the villages contain multiple scattered settlements. The settlement of Brulf near Disentis village was covered in a rockslide in 1689.
