Mount Rinjani Trekking 3Days/2nights Summit Lake Hotspring

Mount Rinjani saves its biggest test for the middle of the trip. You climb from Sembalun to the 3,726-meter summit before sunrise, then descend to Segara Anak Lake and its hot water on the same long day. That makes this a serious trek, not a gentle mountain walk.

I like the route for two clear reasons: you see Rinjani from both crater rims, and the porters carry the tent, food, cooking gear, and sleeping kit. I also like the small group limit of eight people. The main drawback is Day 2, which can stretch from a 2:00 am wake-up until around 6:00 pm, with loose volcanic scree on the final climb.

Key points to know before booking

• The summit comes first on Day 2: You leave camp at about 3:00 am for the sunrise climb.
• Sembalun and Senaru create a full crossing: You start in open meadow and finish through rainforest.
• Segara Anak Lake is the recovery stop: You can rest, swim, and enjoy hot water beside the lake.
• Porters carry the camp: The package includes tents, mattresses, sleeping bags, food, water, and cooking equipment.
• Day 2 is the hard day: The summit, lake descent, lake-to-rim climb, and long walking time demand stamina.
• The advertised price is not the full trip cost: The national park permit, hotel, and pickup transport are extra.

A three-day crossing of Mount Rinjani

This trek covers Mount Rinjani in the most scenic way available within three days. You begin in Sembalun on the eastern side, climb to the summit and Sembalun crater rim, descend to Segara Anak Lake, then cross to Senaru crater rim before walking down through forest.

The route gives you several very different settings. The opening climb crosses open meadow. The summit approach turns into steep, loose volcanic ground. The lake offers a slower pause, while the final descent runs through rainforest. You get variety, but you also pay for it with a demanding second day.

The package costs $169 per person. That is good value if you want a guided trek with porters and camp equipment already arranged. It includes three meals a day, snacks, fruit, three liters of water per person per day, a tent, toilet tent, sleeping bag, mattress, and cooking equipment.

You still need to add the Rinjani National Park permit, listed at IDR 250,000 per person per day. Hotel costs and pickup transport are also outside the package. Keep those extras in mind when comparing the price with shorter or more basic Rinjani trips.

Day 1: Sembalun meadow to the 2,639-meter crater rim

The first morning begins with a 6:00 am wake-up and breakfast. You then drive to Sembalun village, which sits at about 1,100 meters, and check in at the Rinjani National Park office.

The walk begins around 8:00 am. At first, the trail climbs gently through open meadow. This is the least technical part of the trek, and it gives you time to settle into the pace, sort out your pack, and get used to walking in the heat.

After about two hours, you reach Pos 1 at 1,300 meters. The next section takes roughly 40 minutes to Pos 2 at 1,500 meters. From there, you continue toward Pos 3 at 1,800 meters, where lunch is served.

This first section is described as fairly light compared with what follows. That is good news, but do not mistake it for a free day. You are still gaining height, and the summit attempt starts before dawn the next morning. Use the easier pace to drink water, eat properly, and protect your energy.

After lunch and a rest, the trail turns more serious. The climb to Sembalun crater rim at 2,639 meters takes about three hours and includes a long, steep section. The final push can feel slow, especially after the earlier walking and the afternoon heat.

Your camp sits on the crater rim. The reward is immediate: sunset, sunrise, and wide views from high above the mountain. The rim is also a useful place to get your gear ready for the 2:00 am wake-up. Put your warm layers, headlamp, water, and summit essentials where you can reach them without unpacking everything.

The included toilet tent is basic but useful. You are camping, not staying at a mountain lodge, so expect simple facilities and a practical camp setup.

Day 2: A 3:00 am start for Rinjani’s summit

Day 2 is the heart of the trip and the part you need to take seriously. You wake around 2:00 am, have a hot drink and light breakfast, and start toward the summit at about 3:00 am.

The first section is moderate, followed by a longer but fairly manageable climb. As daylight approaches, the trail becomes much harder. The final approach crosses steep volcanic scree, with loose footing that can make each step slide backward.

The stated summit arrival is around 6:00 am. At 3,726 meters, you can look across Lombok and see Bali, Sumbawa, and Segara Anak Lake. Sunrise is the main prize, but the summit also gives you a clear sense of the mountain’s scale.

The summit section is not suited to rushing. Keep your steps short, follow the guide’s pace, and save energy for the descent. The air is colder before sunrise, so a warm layer matters even though the lower parts of the trek may feel hot later.

After spending time at the summit, you descend to Sembalun crater rim in about two hours. Breakfast is served there. This is a welcome pause, but the day is only partly finished.

Next comes a three-hour descent to Segara Anak Lake. Going downhill on loose ground can be hard on your knees, and the long descent follows the summit climb with little recovery time. Trekking poles would be useful, though they are not listed as part of the package.

At the lake, you can rest, swim, and enjoy hot water beside Segara Anak. The warm water is a welcome change after the cold summit start and the rough descent. It is also one of the best reasons to choose this route instead of a simple summit-and-return trek.

Lunch is prepared by the porters. Their work is central to the trip because they carry the food, tent, sleeping gear, cooking equipment, and other camp supplies. You carry your personal items, but the camp reaches each stopping point because the porter team keeps moving ahead with the load.

After lunch, you leave the lake and climb to Senaru crater rim at 2,641 meters. This section can feel especially demanding because it follows the summit and lake descent. You are gaining height again, and the total walking time may run until around 6:00 pm.

Senaru crater rim is the second campsite. The view here is different from Sembalun. You can watch the sunset toward Mount Agung in Bali, while smoke rises from the new volcano on the edge of the lake. After such a long day, that view should be treated as a bonus, not a guarantee that you will still have energy for a long photo session.

A practical warning: Day 2 is not just a summit walk. It combines the pre-dawn climb, the summit descent, the lake descent, the hot-water stop, and the climb to the second rim. If you want a relaxed mountain holiday, this is not the right format. If you want a full Rinjani crossing and accept a very long day, it gives you a lot for the time.

Day 3: Senaru crater rim through rainforest

The final morning begins with breakfast and sunrise at Senaru crater rim. After that, you descend toward Senaru village through rainforest.

The descent takes about five hours, with lunch along the way. Compared with Day 2, this is a lighter finish, but five hours downhill still asks plenty from tired legs. The forest also changes the feel of the trek. After the exposed meadow and volcanic slopes, you get shade and a more enclosed route.

There is a chance to see the rare black monkey. The wording matters: this is a possibility, not a promised sighting. Keep your attention on the trail and enjoy the forest even if no animals appear.

You finish at Senaru village at about 601 meters. From there, a car takes you to your next destination. Since transport after the trek is not included in the package, confirm your onward plan and budget before you start.

What the porters and guide add

The professional guide and porter team are included, along with the main camping equipment and meals. That changes the trip from a self-supported mountain crossing into a guided camp-to-camp trek.

The porter service is especially valuable here. Carrying enough food, water, tents, mattresses, sleeping bags, and cooking gear for three days is a major task on a route with two crater rims and a summit. You still need to carry your own day essentials, but you do not need to haul the full camp.

The food plan includes breakfast, lunch, and dinner, plus fried banana as an appetizer and fruit for dessert. Water is listed at three liters per person per day. That is a useful allowance, though you should treat hydration as a personal responsibility, especially on the exposed Sembalun climb and the long second day.

The guide language is English, and the group is limited to eight participants. A small group should make it easier to keep a shared pace and communicate on the pre-dawn summit climb.

Guide style can vary. The available information points to friendly porters and guides, but also to a guide who was quiet and offered limited conversation for much of the trek. If you want a guide who explains geology, plants, and local culture throughout the walk, ask about the guiding style before paying. If you mainly want route support and camp coordination, a quieter guide may not trouble you.

What is included, and what you still pay

The $169 price covers a substantial amount of practical support:

• Professional guide and porter
• Tent and toilet tent
• Sleeping bag
• Mattress
• Three liters of water per person per day
• Cooking equipment
• Breakfast, lunch, and dinner
• Fried banana
• Fruit

The national park permit is not included. It is listed at IDR 250,000 per person per day. Hotel accommodation is also extra, as is pickup transport.

The meeting arrangement is based on your hotel name in Senaru. Give the provider that information clearly when booking. Since the trek starts in Sembalun but the meeting point is tied to Senaru accommodation, you should confirm the exact morning transport plan rather than assume a pickup is included.

Free cancellation is available up to 24 hours before the activity for a full refund. You can also reserve and pay later. Those terms help if your Lombok plans are still moving, but they do not remove the need to prepare for the physical demands of the route.

Who should book this Rinjani trek?

I would choose this trip if you want the summit, Segara Anak Lake, hot water, and a crossing from Sembalun to Senaru in one package. It gives you the mountain’s major sights without requiring you to arrange a guide, porter team, camp, and meals separately.

It suits hikers who can manage steep climbs, long descents, early starts, and a full day on foot. You do not need to be a technical climber, but the loose volcanic scree near the summit can be difficult, and the second day requires endurance.

I would think twice if you dislike basic camping, struggle with steep downhill walking, or want a slow and social mountain trip. The first day is fairly light, but that mainly prepares you for the very long second day. The third day is easier, yet your legs may still feel the summit and lake sections.

Bring personal layers for the cold early start, sturdy shoes, sun protection, and enough room in your day pack for water and personal items. Pack lightly, because the porters are carrying the shared camp rather than serving as a substitute for sensible packing.

Should you book with Evsi Rinjani?

Book this trek if the value of a supported summit crossing appeals to you. The strongest parts are the two crater rims, the sunrise summit, the lake stop, hot water, and the porter-supported camp. The 4.3 rating from four reviews suggests a generally positive experience, while the practical cautions are clear: guide conversation may be limited, and Day 2 is very hard.

Before booking, confirm the pickup arrangement, the permit cost, and what personal luggage the porters will carry. If you accept the long summit day and basic camps, this is a strong three-day way to see Mount Rinjani from several angles.
