"Eco-friendly adventure at its finest"...


When is the best time to climb Mt Rinjani, and when is the park closed?

Climbing season is from April to January. Climbing can only be restricted during these times if the Volcano becomes more active. At these times The National Park authority sends us notifications and we will advise guests of any route changes. If we have to cancel a trek due to volcanic activity we will refund you in full. Mt Rinjani National Park is closed from mid-January to March due to heavy rainfall.


North Lombok and surrounding areas has a Tropical Climate. Although climbing season is considered dry, you should be prepared to encounter dust, rain, low visibility and slippery tracks all year round.

Average daily temperatures vary; however, temperatures drop with elevation gain. In the evening temperatures range between +2-3°C. Wind-chill should also be expected. For this reason, warm clothing is absolutely necessary.

National Park Entrance Fee

The park entry fee is currently 300,000 IDR per person, this is included in our prices.

How hard is the trek? Can I complete it if I’m a beginner?

Climbing Mt Rinjani is a challenging trek for any guest, so it is important to have some level of fitness. The terrain is varied, but for the most part it involves long steep ascents and descents, with some hazards along the trail (fallen railings, loose rocks, etc). Some bouldering is necessary when descending to and ascending from the lake.

Beginner: I’ve never trekked before or rarely trek/hike.

For those that have never hiked before or regard themselves as having a low level of fitness, this trek will be very hard. On many occasions we have had guests turn back due to early onset of exhaustion. For this reason, we suggest taking a shorter trekking package (Senaru Crater Rim trek). This means you’re more likely to succeed in completing your trek and will still have the benefit of experiencing Mt Rinjani’s incredible views.

Moderate: I consider myself reasonably fit and exercise a few times a week.

Those with moderate fitness levels usually find this trek hard, but rewardingly challenging.

Fit / athletic: I’m an active person with a high level of fitness and/or I’m an experienced trekker.

Experienced trekkers and those with a high level of fitness usually find this trek tough, but more comfortably challenging.

What time will our trek start?

Trek’s usually start at 8am. This means that you are required to be at our office no later than 7am for a briefing, equipment issue, and some breakfast. After breakfast we transport you to the park entrance where you will register, before commencing your trek. For those guests staying in Senaru, we will sometimes complete your briefing and equipment issue the night before.

Do I have to climb the summit?

Guests are not required to complete the summit climb. Whilst it is a challenge worth attempting, guests choosing not to climb can sleep and relax at basecamp until the others in your group have returned from the summit.

What’s the quickest way to the summit… we only have two days?

The fastest route to the summit is from Sembalun – this is the only route for the 2 day / 1 night summit package.

I have to catch a flight after the trek!

If you have a flight to catch directly after your trek, we recommend taking the Sembalun route. It is possible to reach the airport for a 6pm or later flight, but whether or not you make it will depend on your fitness and agility.

Starting points – Senaru or Sembalun?

2 days / 1 night – Summit Package: This trek starts and finish in Sembalun. The village of Sembalun is approximately 75 minutes car journey from our office in Senaru. For this reason, we recommend guests stay in Senaru or Sembalun the night before the trek (Senaru is preferred if borrowing equipment). If you’re staying elsewhere on Lombok the night before the trek (e.g. Sengiggi) we will have to collect you from your hotel early enough to start trekking by 9:30am. Later starts are not ideal as we aim to reach the Sembalun Crater rim before sunset. 5am is our usual collection time if staying in Sengiggi.

2 day / 1 night – Crater Rim Package: This trek starts and finishes in Senaru. We do recommend you stay in Senaru the night before trekking, but it’s not essential. If we are collecting you from Sengiggi on the morning of the trek we will collect you at 5am.

3 days / 2 nights – Mt Rinjani Package: With this package it is possible to start on either side of the mountain. The path taken on both routes is the same, with some main differences:

Senaru > Sembalun:

Day 1. Hiking up through jungle to Senaru Crater Rim (Plawangan Senaru). This is a prolonged ascent, but shaded from the sun for most of the day.

Day 2. Decent down to the lake, visiting the thermal springs, and hiking up to Sembalun Crater Rim.

Day 3. Trekking to the summit, then down off the mountain to the village of Sembalun.


  • Shaded by jungle canopy on day 1.
  • Finish with summit on final day.

Sembalun > Senaru:

Day 1. Hiking from Sembalun village to Sembalun Crater Rim (Plawangan Sembalun). This route progresses from relatively easy, undulating terrain (farmland) to a steep ascent through sparse woodland.

Day 2. Trekking to the summit (2am start) then back down to the campsite at Plawangan Sembalun. After breakfast, hike down to lake Segara Anak & the thermal springs. Lunch at the lake before climbing up to Plawangan Senaru (Senaru Crater Rim). It is possible to spend the night at the lake, but this will depend on whether guests have to travel to another location at a specific time after the trek. If you choose this option it will add approximately 3 hours to Day 3’s itinerary.

Day 3. Hiking down through the jungle to Senaru village.


  • Summit is attempted at the beginning of the trek, which means some guests are less exhausted.
  • Potential earlier return to RDA office and onward location / airport.
  • Possible to catch a late afternoon or early evening flight from Lombok Praya Airport. We recommend booking flights no earlier than 5pm and we cannot guarantee you’ll be on time. The travel time from our office to the airport is approximately 3 hours and this means guests would have to leave Senaru by 1pm (to arrive one hour before check-in).

Thermal Springs

Those choosing a package that includes a decent to the lake (3 day / 2 night or 4 day / 2 night packages), will also have the opportunity to soak themselves in the hot thermal springs. This usually comes as a welcome relief for tired muscles before beginning your next ascent. Those taking longer to complete the trek (staying a night at the lake) will have more than one opportunity to bathe in these lovely waters.

First Aid

A basic first aid kit is carried on all of our trips which includes: bandages, antiseptic, crepe bandages, band-aids, dressings. Customers must carry any personal medication. *Legally we cannot prescribe / give our customers medication, even over the counter things like paracetamol. If taken, customers are recommended to bring small amounts of items that can aid with stomach upsets, headaches, inflammation, etc.


VHF radios and mobile phones are used for communication and to aid in the event of an emergency. *Coverage is limited in some areas.


Illegal drugs will not be tolerated on any trip. Possessing or using drugs not only goes against Indonesia’s strict laws but also puts you, your group and our business at serious risk. Smoking marijuana or using other recreational drugs may be accepted in other parts of the world, but is strictly forbidden for our travellers. Please be respectful of our local people and culture by adhering to these rules, and under no circumstance possess or use drugs during your RDA trek.

Accommodation (Senaru)

High end: Rinjani Lodge. This is a beautiful place with a stunning view and good restaurant – there are also two infinity pools overlooking the mountain and jungle. It may be a great post-trek option. Approx. 1,200,000 – 2,000,000 IDR per night. Rinjani Lodge is roughly 300m from our office.

Medium range: Rinjani Lighthouse. Run by a German family. Traditional style, but friendly and good service. Around 500-600,000 IDR per night. Another option is “Pondok Senaru” – this has a view of Sendang Gila waterfall.

Budget: There are many basic options that range between 200-250,000 IDR per night (including breakfast). These businesses don’t usually have a website, but can usually be found on accommodation booking sites and in most cases, we can book for you.


*We cannot make flight or boat bookings on your behalf*

How do I get there?

Please email your pick-up and drop-off locations when making your booking.


There are many flight options to and from the island of Lombok. Please research the best option to suit your needs if you’re planning to fly.

 Fast Boats: There are many fast-boats operating between Bali and Lombok. We tend to recommend Eka Jaya, as their boats are larger and have air-conditioning. Many of the fast boat operators include a transfer from your hotel to the port of departure (usually Padangbai Harbour if travelling from Bali to Lombok). You can book online, but it’s worth giving the name and telephone number of the hotel you’re staying at, just in case the driver can’t find you. In high-season (July – September) it’s worth booking your fast boat in advance, as they can fill-up. In low-season you can often book a seat the day before or even just turn up at the office in Padangbai and purchase a ticket.

Boats to and from the Gilis (Air, Meno & T) there are 3 options:

Public Boats: These are long narrow boats used by natives and tourists. As well as people, they are often used to transfer small goods. They can be crowded but are relatively safe. They are powered by outboard motors, and are the slowest option – it takes approximately 20-30 minutes to reach the destination island (there are separate boats for Trawangan, Meno and Air). Public boats are the cheapest option and usually cost between 15-25,000 IDR for a one-way ticket. Tickets can be purchased in the ticket office, and should not be bought by touts (locals trying to sell at a hugely inflated price). For more information, you can visit this page.

Public Speed Boat:  A shared speedboat that can seat about 40 people goes from Bangsal to the three islands (and vice-versa). Ticket costs are approximately 85,000 IDR, and they usually leave at a quarter past the hour. These are more comfortable and quicker than the public boats.

Private Charter Speedboats: These are small (5-6 people) and fast. They go direct to your destination when tides permit (if your hotel is on the beach). They cost between 350,000 and 450,000 IDR per boat trip, and leave at any time. Should you need one of these, we can organise in advance.


*Please ensure you check departure and arrival times with your chosen provider.
