Gunung Rinjani National Park (Taman Nasional Gunung Rinjani) is popular for mountain climbs and trekking and represents an important nature reserve and water catchment area. The park is officially 41,330 hectares within the park boundaries and a further 66,000 hectares of protected forest outside. The mountain and its satellites form the Mount Rinjani National Park (Taman Nasional Gunung Rinjani) - officially 41,000 hectares within the park boundaries and includes a further 66,000 hectares of protected forest outside. In 2008, the Indonesian government proposed to UNESCO that Mount Rinjani be one of the world's official geoparks. If this was approved by UNESCO, Mount Rinjani would become the first such geological park in Indonesia.
