The montane forests occur as low as 500 meters elevation on Mount Cameroon. They also occur above 1500 meters elevation on three peaks on Bioko, Pico Basilé (3,011 meters elevation), Gran Caldera de Luba (2,261 m), and Pico Biao (2,009 m). The montane forests are surrounded at lower elevations by the Cross-Sanaga-Bioko coastal forests ecoregion.
