Sembalun is a highland area on the eastern slopes of Mount Rinjani, on the island of Lombok in West Nusa Tenggara. It lies in Sembalun District, East Lombok Regency, in a wide valley surrounded by hills. The drive from Mataram typically takes a few hours, depending on the route and road conditions.
Because of its elevation, Sembalun is noticeably cooler than Lombok's coast, and many visitors come for the mountain air and the views. Mount Rinjani is an active volcano, and its fertile volcanic soil supports the forests, fields and farms that can be seen from the surrounding hills.
Several hills around the valley are popular with walkers, and they vary in difficulty. Trails such as those up Bukit Pergasingan and Bukit Nanggi are steep in sections and can be tiring. Walking times depend on fitness, weather and the chosen route, so allow plenty of time and start early.
Easier options are also available. Bukit Selong, for example, is a lower viewpoint with steps that help visitors reach the top and look out over the patchwork of fields in the valley.
Sembalun is also one of the main starting points for treks on Mount Rinjani, whose summit stands at about 3,726 metres. Trekking in Mount Rinjani National Park requires registration with the park authority, and walkers are expected to go with a licensed guide and, for overnight trips, porters. Trails may be closed during the rainy season or for conservation reasons, so check the current status before planning a trip.
Adventure activities such as paragliding have been offered in the Sembalun area from time to time. Availability, safety standards and conditions vary, so anyone interested should only fly with a licensed, insured operator and confirm arrangements locally in advance.
Some visitors camp on the hilltops to watch the sunrise or sunset. Nights at this altitude can be cold, so bring warm clothing and suitable gear. It is sensible to go with a local guide or residents who know the terrain, follow any rules set by the village or park, and take all rubbish back down with you.
Farming is central to life in Sembalun. The valley is known for vegetables such as potatoes, carrots, cabbage, shallots and tomatoes, and for strawberries, which some farms let visitors pick themselves. Harvest times depend on the season and the weather, so ask locally about what is available when you visit.
Sembalun also has a traditional settlement where houses are built in the local style using natural materials such as wood, bamboo and thatch. These houses reflect the building traditions of the Sasak people, Lombok's indigenous community, and give visitors an insight into the area's history. When visiting, ask permission before entering homes or taking photographs of people.
Some community events may include traditional music or dance. Visitors who show polite interest in local culture and history, dress modestly and follow local customs help keep visits respectful for everyone.
