Nearby Senaru, the gateway to the Rinjani National Park, is a pretty village set in lovely scenery with fantastic views of the volcanic mountain range. The Rinjani National Park is a nature reserve of 41 330 hectares surrounding the volcano that provides many opportunities for eco-tourism.
The whole area is a picturesque haven, featuring magnificent waterfalls, lush and accessible jungle trekking, traditional village, and plantations of tobacco and cashew nuts, grown alongside verdant rice terraces. Senaru is the usual starting point for climbing Lombok's famous volcano, gunung Rinjani.
Other options, for a slightly shorter route to the summit, are Sembalun Lawang and Sembalun Bumbung to the northeast.

Rinjani soars 3726m above sea level and is the second highest volcano in Indonesia, attracting thousand of trekkers and climbers annually. The huge caldera near the top is around 4 kms wide and is almost filled by a beautiful crescent-shaped lake, Danau Segara Anak(Child of the Sea).
The lake is around 230m deep and contains plentiful fish, as well as being home to birds and other wildlife. A smaller volcanic cone, Gunung Baru Jari, was formed a couple of hundred years ago and just from the crater's interior at the edge of the lake. It's been estimated that the force needed to create the new cone and the lake would have been equal to around 300 hiroshima-type atomic bombs.
There are a springs located around the volcano, most importantly "Aik Kalak" on the northeast of the crater, where the volcanically heated waters are said to cure illnesses, particularly skin diseases.

In 2004 the Rinjani Trek won the world Legacy Award for Destination Stewardship and the volcano is recognized internationally as an important eco-tourism destination. The Rinjani Trek, funded by the New Zealand government, has set up a series of programs that involve the local communities and guides, for climbing the volcano and for trekking in the National Park-ensuring better management and safety for trekkers. However, it is always prudent to use an authorized guide, deal with a reputable trekking business and carry as few valuables as possible with you.

There are a variety of different options for climbing Gunung Rinjani, two days one night treks are the shortest available , taking visitors to the crater rim, to view the wide crater and the emerald green lake within. However, the most popular is the three days two nights treks which allows trekkers to climb to the very summit of the volcano, with magnificent views from the highest point on Lombok - taking in the vista of the surrounding mountain range, the lush green landscape below, and the ocean to the west studded with Gili islands and Bali floating in the distance.

The best time to climb Gunung Rinajni is in the dry season from around April to October ,or before the rains start. The sunny days and cooler temperatures make this time of the year the most comfortable for climbing, and enable the clearest views of the stunning scenery both on and around the mountain. It is cold on the mountain at night, so make sure you take warm clothing.
