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.
Although Mt.Rinjani has not erupted in recorded history, Mt.Baru (2,351m) in the crater lake is an active volcano.There was a spate of activity from 1994 to 1995 which resulted in the further growth of the crater cone Gunung Baru, since renamed Gunung Barujari (Finger Mountain).
Most recently, Gunung Barujari erupted three times on 23 May 2010 with activity continuing until 24 May 2010. According to the volcano's official monitoring agency, ash from Mount Barujari was reported as rising up to 2 km into the atmosphere and damaged crops. Lava flowed into the caldera lake, pushing its temperature up from 21°C to 35°C, while smoke spread 12 km. The volcano did not directly threaten villagers during any of the eruptive activity in early 2010, however, access to some sections of the Mountain was officially closed or restricted at some times.
Rinjani is best climbed during the April-November dry season. The trekking trails are generally closed during the rainy season. In recent years the early months of the 'dry season' have become more prone to rain and you should be prepared to encounter heavy rain and low visibility with slippery tracks underfoot at any time, particularly in the afternoon.
It gets very cold on the mountain above 2,000 m and temperatures can be near freezing at the summit. Warm clothing is essential. Also, the sun can be very strong during the day and severe sunburn is a risk.
Entry to the park costs Rp 150,000 per person. This fee is split up as follows: 13% to the national park authority, 62% to the Rinjani ecotourism trekking program and 25% for trek route maintenance. (This cost is included in the price of the Trek).
MOUNT Rinjani is very climbable by visitors who have a high level of physical fitness.
It is critical to understand and respect this great mountain.
It takes a very strenuous effort to reach the actual summit, which is steep and includes sections of very loose gravel.
When you reach the rim (2,700m) you will see that the views of the crater lake are also mind blowing.
To make the extra 1,000m ascent to the very top (summit) requires a considerably higher level of fitness, as well as strength of spirit and sense of adventure.
