The Bamenda Mountains are located in the Cameroonian province of North- East, about 15 km southeast of the provincial capital Bamenda . They form their own volcanic complex in the northeastern extension of the Bambouto massif , which reaches its greatest height on the 2621 meter high Neshele . Its summit area is dominated by two volcanic craters , in whose lower crater is Lake Bambili . The volcanic massif covers an area of ​​approx. 600 km² in the Bamenda highlands and is the fourth highest volcanic complex on the Cameroon line and the sixth highest point in Cameroon .

On the southwest and southeast flanks of the massif are the Santa Mbu (6 × 4 km) and Lefo caldera (4 × 3 km), the crater bottom of which sinks to 550 and 400 meters above sea level, respectively. The massif consists mainly of basalts , trachytes , ignimbrites , rhyolites and phonolites , these are built up in layers of different thicknesses and lie over a bedrock consisting of gneiss and granite . The age of the volcanic rock types could be dated to 27.40 to 18.98 million years by means of radiometric investigations.

The climate in the Bamenda Mountains is called tropical humid, with a main rainy season between March and October. It reaches its peak with the arrival of the West African monsoons from June. From November to February, the massif is influenced by the north-east trade wind , which is called Alizé in the region. Temperatures vary between 21 and 24 ° C all year round.
