Mount Oku
North-West
Mount Oku, also known as Kilum Mountain, is the largest volcano in the Oku Massif within the Cameroon Volcanic Line. Rising to 3,011 metres above sea level, it features a large caldera and diverse geological formations including basaltic, hawaiitic, trachytic, and rhyolitic lavas. The mountain supports the highest sphagnum bog in West Africa near its summit and hosts the largest remaining patch of montane forest in the region, the Kilum-Ijim forest. This forest is a critical habitat for numerous endemic species of flora and fauna, many of which are endangered. Conservation efforts led by BirdLife International and local communities have helped regenerate the forest after significant losses due to human activity. The montane grasslands above the forest support unique endemic wildlife, making Mount Oku an ecological treasure and a vital area for biodiversity in West Africa.

History
Mount Oku's volcanic activity dates back approximately 24.9 to 22.1 million years ago, with more recent eruptions forming pyroclastic cones and explosion craters.
The mountain's geological evolution has shaped its current structure, including a large caldera and Lake Oku within one of its craters.
Over centuries, the surrounding montane forests have been affected by human settlement and agriculture, leading to significant deforestation in the mid-20th century.
Since 1987, conservation projects have been implemented to restore and protect the Kilum-Ijim forest, involving local communities in sustainable management practices.
