Monte Buio is a mountain in Liguria, northern Italy, part of the Ligurian Apennines.

[2] The mountain has grassy slopes and on its summit stands a large cross.

[3] There are several hiking paths reaching the summit of Monte Buio, starting from Alpe and Vallenzona (two villages of the comune of Vobbia), from Tonno (Valbrevenna) and from the mountain passes of the Incisa and San Fermo.

[4] The summit offers a good point of view on the nearby valleys and from it also the Ligurian Sea and a large stretch of the Western Alps can be seen.

[5] The Ligurian side of the mountain since 1989 is included in the Parco naturale regionale dell'Antola[6] while the Piedmontese one is part of the Parco naturale dell'Alta val Borbera.
