Talassemtane National Park covers 589.5 km² of the western Rif mountains next to Chefchaouen and was created in October 2004 to protect the last of Morocco's threatened fir forests. It holds the country's only native stands of Spanish fir (Abies pinsapo) along with Atlas cedar, more than 1,380 plant species — 47 of them found nowhere else in Morocco — Barbary macaques, Greek tortoises and over 100 bird species including the bearded vulture. BirdLife International lists it as an Important Bird Area, and its best-known walking routes lead to the Akchour waterfalls and the natural arch known as God's Bridge.
