Indonesia – Mt Rinjani – Aik Berik Rim Trek

Indonesia – Mt Rinjani – Aik Berik Rim Trek

Mount Rinjani (3726m) is the second highest volcano in Indonesia, second only to Mount Kerinci on Sumatra. It is an active volcano that is part of the “Ring of Fire” and dominates the landscape of the relatively small island of Lombok.

In August 2018, the unfortunate tremors on Lombok caused damages to the trails on Mount Rinjani. The trails to the summit and crater lake have been closed since, until surveys on the safety of the routes are completed.

The good news is that the Mount Rinjani National Park Agency (TNGR) has re-opened the trails to the rims - Sembalun, Senaru and Aik Berik in June 2019!

Aik Berik is an existing old trail that leads to the south rim. This trail, via Aik Berik village, on the southern slope of Mount Rinjani, was not damaged by the tremors. The approach to the south rim includes trekking through dense forest, which gives plenty of shelter from the scorching sun. On most parts of the trail, it is possible to spot the city of Mataram and its grand mosque from Umar Maye Rim. The view from the rim is spectacular.

This south rim trek do not lead to the summit nor to the crater lake (Segara Anak).

**Our aim of organising this trek is to bring trekkers back to Lombok to support the local community and economy. Almost 100% of tourism operations in Lombok are back in business. However, many of the trekking guides and porters are still jobless as the summit and crater lake of Mount Rinjani remain closed.

About The Trek

The trek to Mt Rinjani's south rim is via Aik Berik village.  We will start from Senggigi, drive about 1.5hrs to arrive at Benak Stokel, before that, we will stop over at the National Park office for registration.

We hike through the tropical rain forest with opportunities for wildlife viewing.  It takes about 3.5hrs  to reach our lunch point (Kayuk Malang/1400m), after lunch, it is another 4hrs walk to reach the south rim (Umar Maye Crater/2500m). We will camp overnight at the crater rim;  the dazzling sight of the crater lake, Segara Anak is in full view on a clear day.

The next day, we enjoy the spectacular view of the sun rising, casting lights onto the crater lake.  After breakfast, we descend using the same route to return to Benak Stokel, then take the vehicle to Senggigi.

Trekking Seasons

The monsoon season in Lombok is from December to early March. During this period Mt Rinjani will be closed for trekking by the National Park and is usually opened from mid March onwards.  The rainy season can last through March to April and the rain can start to pour from November. Hence, the best period to trek Mt Rinjani is from May to October.

Grading: 2A

Training: Regardless of your level of fitness and physical conditions, it is advisable to train prior to embarking on a trekking or mountain climbing trip.

Pure cardiovascular fitness is NOT enough.

Focus your training effort in the following areas, assuming that you are in good health and injury-free:

  1. Climbing conditioning – stairs and load training.
  2. Cardio training - Jogging/running and interval training like CrossFit or HIIT.
  3. Strength training for the lower body, shoulder, back and core
  4.  Flexibility training - eg: Yoga and stretching exercises

A good three months of training would be a good preparation for this trek.

A recommended training guide specific to the trek or climb will be given to you upon signing up.

Refer to our Grading chart for an overview on the technical difficulty and fitness required for this trek.
