Buntu Rantemario, Mountain summit in South Sulawesi, Indonesia.

Buntu Rantemario is the highest summit of the Latimojong range in Tana Toraja, South Sulawesi, Indonesia, sitting at around 3,478 meters (11,410 feet) above sea level. It rises through forested highland terrain crossed by several climbing routes that link a number of basecamp locations.

The Latimojong range appears in colonial-era records as a forested highland between Enrekang and Luwu, with Rantemario noted as its highest point. The name Latimojong is used locally for both the range and the peak, while Rantemario is the summit name. The mountain is climbed from Karangan village, and eight staging points have been designated along the route, some with water and camping.

The mountain sits within lands connected to the Toraja people, who continue their traditional ways in surrounding villages. Local communities view this highland region as integral to their cultural identity and daily connection to the land.

The climb starts from Karangan village, where marked trails lead up the mountain. Water sources are available at set rest points along the way, so carrying a refillable container makes the ascent more manageable.

The area near the summit is covered with moss-laden trees that grow in this highland climate, giving the top a distinctly different look from the forested slopes below. On clear days, the coastlines of both South and West Sulawesi are visible from here.
