The Allah Valley (at times also spelled Alah) is a large valley of the Allah River in the provinces of South Cotabato and Sultan Kudarat on the island of Mindanao, Philippines. It is formed by the Roxas-Matulas Range in the north and the Daguma Mountain Range in the south.
The valley is known for its natural environment, such as Lake Sebu, Lake Holon, Baras Bird Sanctuary, and Esperanza Hot and Cold Springs. On the other hand, it is adversely affected by flooding, siltation, riverbank migration, unstable agriculture production, and upland degradation, as well as illegal logging.
The entire valley was declared a watershed forest reserve in 1985 through the signing of Proclamation No. 2455. The 102,350-hectare (252,900-acre) protected area also includes Lake Sebu, the Tasaday-Manobo Special Forest Reserve, the Datu Ma Falen Civil Reservation, and the National Cultural Minorities Settlement Reservation located within the valley.
The bestselling Lonely Planet described Lake Sebu as a place located in a “bowl of forests and mountains.” The 42,450-hectare landscape consisting the domains of the Allah Valley is recognized by United Nations Educational, Scientific and Cultural Organization (UNESCO) as a cultural landscape in Mindanao.
It is a well populated valley with fertile soil, bisected by the Allah and Banga Rivers (tributaries of the Pulangi River). The placid lake of Lake Sebu can be found in the upper part of the Allah Valley. Its elevation ranges from 439 to 1,814 feet (134 to 553 m).
Municipalities in the valley
Companies are starting to invest to build factories in the area especially in the municipalities of Surallah and Tboli. Especially eco-tourism is being promoted as a means to boost the region's economy.
