Bagging It!

We currently know very little about this peak in Western Sumbawa except that it is also known by local people as Puncak Ngenges or Puncak Ngengas. One report states that it takes ten hours to reach the top from Desa Tepal and that there is a large trig pillar at the top. The Bakosurtanal map calls the mountain range Pegunungan Puncak Ngengas, but the highest peak is not labelled and the name ‘Olet Sangenges’ probably comes from ‘Olat Sangengas’ a lower peak at 1,683m around 3 kilometres away to the east.

UPDATE 2017: Ega Satria Anugrah and friends climbed this in August 2017. He suggests the height may be as much as 1871m – the figure on the Bakosurtanal map – and this needs confirming with a GPS device.

You need 4 or 5 days in total. Starting point is Marente/Marenteh which lies to the north of the mountain range.

A vague itinerary may be along the following lines….

Day 1: arrive in Sumbawa Besar on first flight from Lombok (Wings Air). Proceed to Marente and hike to Pos 3 (up to 10 hours total).

Day 2: Pos 3 to Pos 5 (9 hours).

Day 3: Pos 5 to summit (2.5 hours) and back down to Pos 3 (a full day of 12 hours possible).

Day 4: Return to Marente and on to a hotel.

Day 5: Fly out from Sumbawa Besar.

We hope to hike Olet Sangenges in 2020…….

  1. I bagged it in December 2019, published a video on YouTube.

    I wrote a full report on how to get there and our preparations, 200 pages of it, hiked from Tepal to Marente (crossed the whole Puncak Ngengas mountains).
    Feel free to send an email if you wanna ask, I can also accompany you if you want to make the cross, in late 2021.
    I hope the mountain receive more recognition as the vegetation there is still very thick.

      Videonya hebat. Sangat professional. Prestasi naik dari Tepal ke puncak dan turun ke Marente sangat lmpressif. Aku ke Tepal naik motor tahun 2015. Kawasan itu indah sekali. Orang setempat sangat ramah tamah. Thanks for posting and congratulations on your trek.

  2. I was planning to hike this mountain as my final trek of summer 2018, but after the multiple and ongoing earthquakes in nearby Lombok (some with epicentre only 50km away) it seemed sensible to postpone indefinitely.
    There is no ordinary trail, and we had planned for 3 nights in the forest. I was then hoping to stay on the Gilis for 2 nights but many of the buildings there have collapsed and there could be further devastation and earthquakes. SO best steer clear for the time being.
    If anyone gets round to this, good contacts are Bang Jale (08234 1162314) in the village of Marente and Yudi (0823 4149 4671) in Sumbawa Besar where the nearest airport is.
