Lembah Indah Hot Spring (Beautiful Valley) is a natural sulphurous hot spring in the highland area surrounding Malang in East Java, situated in the volcanic landscape of the Arjuno-Welirang volcanic complex at altitude in a setting of tropical montane forest, tea and coffee plantations, and the cool highland air characteristic of East Java's interior mountain region. The sulphurous thermal waters, heated by the volcanic geology of the Arjuno-Welirang mountains, provide natural mineral bathing valued locally for skin conditions and musculoskeletal relaxation in a forest setting quite removed from the beach and coastal hot spring environments of other Indonesian thermal destinations. Malang's position as East Java's most pleasant highland city — with its Dutch colonial architecture, Singosari Kingdom ancient Hindu temples, the Batu Malang apple and strawberry farms, and access to the extraordinary Bromo-Tengger-Semeru National Park and its moonscape caldera — creates one of Indonesia's most diverse and culturally rich highland city landscapes. Lembah Indah's natural sulphurous bathing in the Malang highlands complements perfectly the extraordinary volcanic and cultural tourism of East Java's most visited interior mountain region.

Insider tip — Lembah Indah, meaning Beautiful Valley in Javanese, sits in the cool agricultural highlands surrounding Batu city at the foot of the Arjuno-Welirang volcanic massif in East Java. The sulfurous spring water at 38°C flows from fumarolic vents associated with Gunung Welirang, an active volcano whose crater vents sulfur just 15 kilometers away. Apple orchards and strawberry farms surround the site, giving the highland air an unusual fragrance that contrasts with the mineral spring smell. The valley floor setting with mountain views makes this one of East Java's most scenic natural bathing spots.
