Climbing
The mountain is described as an easy hike through an alpine landscape unusual for Indonesia, with rolling forest glade and open paddocks before the final climb; from the summit, views extend from Timor-Leste to the north toward the clouds above Darwin to the south.1 The standard route starts from a man-made lake at 1,766 m, 8 km beyond the village of Fatumnasi at 1,527 m, which lies about an hour inland from Soe via Kapan, and reaches the summit in 3 to 4 hours.1
Measurement and naming
Peakbagger records a topographic prominence of 1,970 m with a key col at 447 m and a true isolation of 146.53 km, and lists the peak as an Ultra of the Malay Archipelago and the highest point of Nusa Tenggara Timur province.2
The name Nuaf Nefomasi is also borne by a separate, much lower peak: Nuaf Nifumnasi in North Central Timor Regency has an elevation of 958 m and coordinates about 9°17′S 124°45′E, distinct from the main summit's position.3
