Bukit Kaba Natural Hot Spring is a geothermal bathing site on the slopes of Gunung Bukit Kaba, an active stratovolcano in Rejang Lebong Regency in Bengkulu province of Sumatra, Indonesia, where volcanic activity drives naturally heated mineral waters to the surface in a lush equatorial forest setting. The spring is part of a geothermal complex associated with Bukit Kaba's ongoing volcanic activity, and its naturally heated waters provide a dramatic and authentic encounter with Sumatra's living volcanic landscape. Visitors combine geothermal bathing with exploration of the surrounding protected forest reserve, where the biodiversity of Sumatra's equatorial rainforest surrounds the volcanic spring in one of the region's most impressive natural environments.
Insider tip — Bukit Kaba is an active volcanic peak in Bengkulu province, and its lower flanks are dotted with geothermal vents where sulfurous water seeps to the surface through volcanic soil. This natural hot spring requires a short trek through secondary rainforest to reach, and the undisturbed setting rewards the effort with a genuine wilderness bathing experience. The Bukit Barisan mountain scenery at roughly 1,900 m elevation provides a dramatic backdrop. Carry water, as the springs are non-potable and the nearest supply is in Kepahiang town.
