Crystal Mountains National Park, National park in Komo Department, Gabon.

Crystal Mountains National Park is a protected area in the mountainous Komo region with peaks reaching nearly 900 meters high. The landscape features dense forests with varied vegetation and forms an important part of the Atlantic coastal forests of West Africa.

In 1985 the IUCN and WWF studied the Monts de Cristal cloud forest, and a 1990 IUCN report by Chris Wilks proposed protecting 410,000 ha around the Mbé sector. Surveys backed by WCS and WWF began in 2001, and the park was created by decree no. 611/PR/MEFEPEPN of 30 August 2002 as two sections, Séni in the north and Mbé in the south, about 40 km apart.

The park's two sections, Mbé in the south and Séni in the north, are separated by a band of about 40 km. Villagers living along the edges and in the buffer zone are mostly elderly, with an average rural age of 31.6, as younger people have moved to nearby towns for school and work.

The park is reachable by car from Libreville airport in a few hours and offers trails through different forest types. The best time to visit is during the drier months when paths are easier to navigate.

The park's two sections, Mbé and Séni, are separated by a band of about 40 km. The 1990 IUCN report, drafted for Gabon by Chris Wilks, proposed a 410,000 ha reserve bounded by the Mbé and Abanga rivers, the Komo river and the Equatorial Guinea border.
