Why Book with Green Rinjani
The Green Rinjani Difference
Green Rinjani is more than a trekking operator — it’s the reflection of over a decade of honesty, education, and environmental care.
Since 2011, we have guided thousands of trekkers to the summit of Mount Rinjani with one clear purpose: to inspire people to respect nature while enjoying its beauty.
For us, climbing Rinjani is not only a physical adventure — it is a personal journey.
Every hiker comes with a different purpose: some seek challenge, others come for the sunrise, the photography, or simply to breathe the mountain air and feel alive.
That’s why we encourage all trekkers to respect one another’s path, keep peace on the trail, and remember that this sacred mountain belongs to everyone.
Leading by Example
When you choose Green Rinjani, you are not just booking a trek — you are supporting a movement built by local people, driven by passion, integrity, and love for Mount Rinjani.
From the very beginning, we set out to prove that tourism can protect nature, empower communities, and educate others.
Over the years, our actions have spoken louder than any advertisement:
- We introduced the Zero-Waste Trekking Program, reducing plastic waste on the mountain.
- We organized Tree Planting and Reforestation Projects around Senaru and Sembalun.
- We ensured fair treatment and wages for our porters and guides.
- We built transparent, sustainable operations that put guest safety and environment first.
These initiatives have inspired many new companies to follow our path — improving their own practices, upgrading equipment, and showing more respect toward local workers.
We are proud of this influence, because our mission has never been competition — it has always been transformation.
Our Commitment to Sustainability
Today, Green Rinjani stands recognized not just for its service quality but for being a leader in environmental care, safety, and community involvement.
We work closely with the Mount Rinjani National Park Authority (BTNGR) and local ranger teams to keep the trails clean, safe, and accessible for future generations.
Our ongoing community programs include:
- Supporting local education for children in Senaru and Sembalun villages.
- Providing employment and fair wages to local residents.
- Promoting eco-awareness among visitors and partners.
By trekking with us, you directly help sustain these initiatives.
The Green Rinjani Spirit
We are not here to follow trends — we set them.
We are not imitators — we are educators.
Every step we take represents a commitment to the mountain we call home.
We believe that small, consistent actions can inspire bigger change — and that’s exactly what has happened.
Many companies now practice what we started years ago:
- Responsible trekking,
- Zero-waste systems,
- Fair porter policies,
- And sustainable adventure operations.
If others walk the same path today, that means we have achieved our purpose — to inspire transformation.
A Legacy of Honesty, Care, and Community
Green Rinjani stands as living proof that one local initiative can grow into a force of positive change for an entire mountain ecosystem.
Every trekker who joins us becomes part of that legacy —
a story of honesty, compassion, and sustainability that continues to protect Mount Rinjani and empower the people who live around it.
We are Green Rinjani — The Original Eco-Trekking Company Since 2011.
