Mount Rinjani National Park lies on the Wallace Line, a transitional zone between Asian and Australian ecosystems. This unique position has created a rich tapestry of flora and fauna. The park’s terrain ranges from lush tropical rainforests on the lower slopes to windswept alpine meadows and savannas near the summit.

• Flora: The park is home to a variety of plant life, including the iconic Javanese Edelweiss (Anaphalis javanica), which thrives at high altitudes, as well as orchids, towering fig trees, and casuarinas.

• Fauna: Trekkers may encounter diverse wildlife, such as the long-tailed macaque, the rare and shy ebony leaf monkey (lutung), barking deer, and numerous bird species, including the endemic Rinjani scops owl and various honeyeaters.
