Mount Rinjani : The True Beautiful of Nature

Mount Rinjani (Gunung Rinjani) is an active volcano in Lombok, Indonesia.

At 3,726 m, Rinjani is the second highest volcano in Indonesia, second only to Mount Kerinci on Sumatra, and it dominates the landscape of the relatively small island of Lombok.

Within its huge 50 km² caldera sits the crater lake Segara Anak (Child of the Sea). Eruptions within the caldera have formed a new small cone called appropriately enough, Gunung Baru (New Mountain). Segara Anak has a natural hot spring.

The mountain and its satellites form the Mount Rinjani National Park (Taman Nasional Gunung Rinjani)- officially 41,000 hectares within the park boundaries and a further 66,000 hectares of protected forest outside.

In 2008, the Indonesian government proposed to UNESCO that Mount Rinjani be one of the world's official geoparks. If this was approved by UNESCO, Mount Rinjani would become the first such geological park in Indonesia.

Things must See :

• Segara Anak, the crater lake

• Aik Kalak hot springs, at the crater rim

• The Mulang Pakelem. This annual Hindu ceremony at the crater lake dates from the 18th century invasion of Lombok by Balinese from the kingdom of Karangasem and attracts hundreds of participants. The lake is sacred to Hindus and the sight of hundreds of white clad Hindu pilgrims sitting and praying here is a wonderfully uplifting experience.

• Gua Susu (Susu Cave). One of the three famous caves (Gua Susu, Gua Payung, dan Gua Manik) at Rinjani

Climbing Mount Rinjani

The Basic

At 3,726 m, Rinjani is the second highest volcano in Indonesia after Sumatra's Gunung Kerinci. It is very climbable by visitors with a high level of physical fitness. Critical is to understand and respect this great mountain: sadly, visitors have died here through failing to follow sensible procedures and make all necessary preparations.

Few actually make the very strenuous effort required to reach the actual summit but instead stop at the crater rim (approx 2,700 m) where the views of the crater lake are mind blowing. To make the extra 1,000 m ascent to the very top requires a considerably higher level of fitness, not to mention strength of spirit and sense of adventure.
 
Typically, a trek to the crater rim involves two days and one night on the mountain. The longer ascent to the summit can be done with just one night's camping but is often part of a longer trek of 3-4 days and two or three nights.

The current park entrance fee is Rp 150,000. Of this 13% is allocated to the Gunung Rinjani National Park, 62% to the Rinjani Trek Ecotourism Program and 25% to support the Rinjani Trek operation and maintenance program. 
 
An organised trek is by far the easiest, safest and most popular option but it is also quite possible to make all of your own arrangements and just hire a guide and equipment from one of the trekking centres on the mountain. Rinjani Park regulations stipulate the use of a certified guide so even the most experienced and well prepared mountaineers will still need to climb Rinjani with the services of a professional guide. The mountains Licensed Guide Association (HPI) issues certification to the Rinjani guides and porters but it should be understood that the certification standards and required training are no where near as rigorous as would be expected in many other countries. Serious accidents including fatalities do occur on Rinjani treks when led by these accredited guides.

Proper sturdy climbing/hiking boots are an absolute necessity as is a substantial waterproof, windproof jacket, and a head lamp. If you are going to the top, use of poles (walking sticks) for getting through the scree (loose rock) at the top are also highly recommended. By 2,000 m, you will feel like you are not in the tropics any more as rising wet, hot air loses its temperature and may fall as rain. If inappropriate clothing becomes wet difficulties will set in as air temperatures towards the summit are as low as 4⁰C, often with a significant extra wind chill factor. You must prepare accordingly.

Guides and trekking providers

At times it seems that everyone in Lombok is a trekking guide for Mount Rinjani, especially on the main tourist strip in Senggigi.

Take most of what you are told with a pinch of salt and you will find the most experienced and reputable guides at the main trekking centres at Senaru and Sembalun Lawang. It does happen that tourists who are highly experienced hikers or climbers may find themselves far better prepared and skilled for mountain conditions than the local guides. Codes of conduct have been developed for the local trekking support community that include climbing safety, environmental awareness and responsible use. Some of the guides and trekking organisations are better than others at respecting these agreements and guidelines. It is also a good idea to independently check for any volcanic alerts that may have been issued for Mount Rinjani.

Many visitors have found it is preferable to avoid package deals purchased away from Senaru, and instead negotiate either with one of the trekking providers listed below or with the guides themselves to ensure that they are actually competent. If there is a problem, you can then find a different guide company in Senaru or Sembalun.

To help you judge the experience, abilities and equipment provision of a potential guide and support team it may assist to consider the following:

• preparation for rain squalls such as waterproof covers for equipment and supplies, personal raincoats or emergency ponchos
• ensuring that all trek participants are provided with clothing suitable to the conditions and provided with a thermally protective layer such as polypropylene
• first aid equipment and training including treatment for exposure, provision of supplies such as emergency splints for fractures and space blankets
• provision of a trowel or fold-away shovel for burying human waste and the provision of toilet paper
• if the guide team are cooking or handling food are they going to wash and clean their hands, all plates and utensils using detergent/soap
• ensure that the guides and porters understand how to pitch their supplied tents and can demonstrate that the tents are complete.
• ensure it is demonstrated that the tents can be pitched using adequate pegs and with the fly sheets secured away from the tent so that moisture does not seep in even if it is windy and raining.
• provision of a route map detailing emergency assembly points and demonstrate a capacity to communicate a position to a rescue party
• that an emergency management plan is in place in case of accident or other emergency during the climb
• availability of a working mobile phone for emergency calls and provision of a SIM card that has sufficient credit to deal with communications in an emergency
• availability of a serviceable VHF hand held radio with two fully charged batteries and a capacity to use it in case of emergency.
• availability of a satellite phone in serviceable condition, in service, with active network reception and supplied with a fully charged battery

Mobile phone reception is good on the entire mountain except within the crater.
Guide fees are generally negotiable. Only the Rp 150,000 park entrance fee is set by the park authority. A sensible package price range would be:

• 2 days, 1 night trek to the crater rim only: Rp 1,500,000-2,000,000 per person.
• 4 days, 3 night trek: Rp 2,500,000-3,000,000. 

These trekking fees will vary though according to how busy the guides are, how many people are in your party and if a commission is due to a referring person or agency. Some guide companies will charge as little as Rp 900,000 per person for a 2-night trek in the off-season, but it is important to check they are properly experienced, equipped and provisioned. Ensure your trek price is all-inclusive of any extra charges for transportation, provisions, porter fees and the park entrance fees.

For the sake of future generations, please check that your trekking operator adheres to the 'pack it in / pack it out' policy for litter, and ask all your participants to take responsibility for collecting their own litter and carrying it out.
