Alas Mertajati — Customary Forest Trekking
Alas Mertajati is a 1,298-hectare customary forest that has been protected by the Adat Dalem Tamblingan community for centuries. Located at an altitude of 1,200–1,400 metres above sea level, the area offers a unique trekking experience that is both culturally and spiritually profound. Trekking in Alas Mertajati is not ordinary nature tourism — visitors are guided by members of Brasti (Baga Raksa Alas Mertajati) who share stories of the indigenous community's struggle, the forest's biodiversity, and the philosophical values embedded in every tree and spring. Within the forest lie 17 ancient roofless temples, various medicinal plants, and diverse endemic flora including locally named trees such as kalijee, kejuang, lentoro, pelindo, and gintungan growing naturally throughout the forest.
