Given their close proximity to the huge Gunung Rinjani, the grassy mountains to the east of Sembalun are easy to overlook. However, these pleasant ridges provide some outstanding views to both Rinjani and eastwards to the ocean and the island of Sumbawa and are well worth a hike in their own right.
Gunung Sempana (‘Montongkeliun, 2,326m’ on the Bakosurtanal map) is the highest and for that reason arguably the finest viewpoint. Just a few years ago, nobody had heard of this and only the lower Pergasingan Hill was trekked by those looking for something much easier and shorter than Rinjani. But in 2021, Sempana is a popular camp spot with locals on weekends and what a fabulous viewpoint it is in the early morning.
From Sembalun Bumbung (south of Sembalun Lawang where the Rinjani trailhead is), a farm track leads from the simple wooden ticket office and warung (1,204m) into the heart of the hills. You can take your bike or go with a guide to save perhaps 30 minutes of walking. A small parking area (1,266m) and sign pointing across a bamboo bridge mark the formal trailhead.
The trail then leads through farmland, past a wooden hut (1,310m) before entering forest. There is a pleasant rest area (1,459m) before the trail emerges from the forest (1,502m) and onto a grassy ridge that gets steeper and steeper as the path zig-zags up the mountainside. At one point there are some simple wooden steps to help you (1,888m).
After a total of less than 3 hours you will be up on the ridge, which has some lovely cemara trees on it and is a popular spot for camping (2,239m). On the other side of the Sembalun valley is, of course, Rinjani itself, framed beautifully by the cemara trees. If you head to the left (north) for just two minutes, you will reach the highest point of the ridge here (labelled Atas Timuk, 2,255m on the Bakosurtanal map but not popularly known by that name). Over to the east is the coastline and two flat islands Gili Lawang and Gili Sulat. Further east is Sumbawa, and you may be lucky enough to see Gunung Tambora in the distance.
Those wanting to reach the true summit of Gunung Sempana have another 40 minutes or so of hiking ahead of them, following the ridge southwards via some more good camping spots and then a little bit of forest (2,196m) before the col (2,170m). The trail then rises up past a transmitter of some sort (2,269m) which is another popular camp spot before reaching the true summit of Sempana and the highest top of all of these eastern hills.
To descend to the trailhead takes less time, so the entire hike can be accomplished in 6 hours or so by most.
Gunung Sempana is also one of the ‘Seven Summits of Sembalun’, a list created recently that includes Rinjani, Sempana and five other tops to the east of Rinjani. There is a challenge to reach all seven peaks in the shortest time possible, and at least one runner has done it in under 24 hours though most teams require 4 days!
The other five on the list are Gedong Lembah, 2,200m (‘G. Lembah, 2,194m’ on the Bakosurtanal map), Kondo, 1,934m (‘G. Seribu, 1,934m’ on the Bakosurtanal map), Anak Dara, 1,923m (‘G. Dara, 1,921m’ on the Bakosurtanal map), Pergasingan, 1,806m (‘G. Pegasingan, 1,793m’ on the Bakosurtanal map) and Bao Ritip, 1,500m (‘G. Sengkor, 1,495m’ on the Bakosurtanal map). Quite why some of the names on the Bakosurtanal map seem to have been updated or ignored or were simply wrong at the time the map was made is not clear, but Bakosurtanal are usually very accurate so perhaps some of these new names have simply been invented recently!
Indeed, there are several others peaks in the area, namely Bukit Nanggi (G. Iyasa, 2,039m on the Bakosurtanal map) which lies south of the Sempana ridge. Bukit Suwarna (G. Adas, 1,899m on the Bakosurtanal map) and Bukit Pal Jepang (G. Tanakiabang, 2,259m on the Bakosurtanal map) are between Sempana summit and the highest point of the road running north-south between the mountains (known as Pusuk Sembalun and roughly 1,635 metres above sea level).
To the west of the road, on the Rinjani side, Gunung Kanji (2,065m) lies north of Gedong Lembah and south of the popular Savana Dandaun. A second savana to the west of the main road lies just north of Kondo and is called Savana Propok. There are also hot springs (Sebau) a short walk to the east of the main road.
