Zainal, lead guide of Mount Rinjani Adventures, on the crater rim of Mount Rinjani with the summit catching the first light behind him

Meet Zainal

I was born in Sembalun, at the foot of Rinjani, and I have guided more than 500 treks to the summit. When you book here, I am who you are booking with.

The guide is the difference

Rinjani is not a walk. It is loose volcanic scree at two in the morning, weather that turns in minutes, and a summit push that asks everything you have. On terrain like that, the person leading you matters more than anything else in the package.

I grew up in the village where the Sembalun route begins. I know the mountain the way most people know their own street: every loose rock, every weather sign, every shortcut that saves an hour when the clouds roll in. I built this operation myself, with a team of guides and porters from the villages around the mountain.

There is no call centre and no reseller in between. Send a booking request and I read it. Message on WhatsApp and I answer. Climb, and I or one of my senior guides climbs with you.

What you can check

Plenty of operators promise the world online. Rather than stacking badges, here is the concrete, checkable core of who we are.

National park registration
Every guide and porter on the team carries an official TNGR / eRinjani ID card from Rinjani National Park. This is the same card rangers check at the trailhead gate, so you will see it verified in front of you on day one.
My guide number
ER202508033780, issued by Balai Taman Nasional Gunung Rinjani, the national park office.
Registered business
CV. Mount Rinjani Adventures, registration S.2653KT/WPJ.31/KPO603/2017.
Local association
Member of the local guide and porter association.
Professional training
Part of the team has completed the HPI (Indonesian Tour Guide Association) guide training and holds the certificate. Training places are limited, so more of the team join as new sessions open.
Insurance, checked for real
Travel insurance with helicopter evacuation is a park requirement, and I actually check yours before arranging permits. No policy that covers it? You can add the park’s premium insurance for IDR 290,000 (about USD 16) per person.

The first time I climbed Rinjani, I was carrying

I was sixteen, and I went up as a porter. Only once. It was so hard that somewhere on the way up I wanted to give up, and I could not, so I kept walking. Then I knew what I wanted: to come back to this mountain as a guide.

There was one problem. Guides speak English, and at school I never cared about English. So I signed up for a course on Lombok, and I learned it there.

So when I see you slowing down on the way to the summit, I know what it feels like. I have been there, with a load on my back. That is why I choose the porters and guides on my team myself.

On the easy stretches you will hear us singing. If it is Viva la Vida, that is probably me.

You climb with a team

Nobody guides Rinjani alone. Alongside me walks a crew of guides and porters who carry the camp, cook fresh meals on the mountain and set up your tent before you reach it.

I plan every trek and stay in touch with you from the first message to the drive home, but I do not walk every group up myself. Your guide may be me or one of the licensed guides from my team in Sembalun, and you meet them at the guesthouse before the trek.

Sun is one of the senior team members. He helps lead the treks, looks after guests from start to finish and makes sure everything runs smoothly and safely. Many guests remember him by name, and you will find him in the reviews.

Zain and Aman were the best guides I could ever have. I started Rinjani feeling like I made a mistake, but Zain and Aman kept spirits up the entire time.

They fed us really well and made sure we were always taking the safe route. Zain was also always singing and making the atmosphere fun.

The guide Datu Daha was excellent, he made the experience especially enjoyable. It was very well organised, food and porter services were incredible.
