Mount Rinjani Summit & Lake Trek: 3 Days, 2 Nights (Sembalun – Senaru)

It is highly recommended to book your trek at least 2 to 4 weeks in advance, especially if you plan to climb during the peak season (July and August).

Important Note: The Mount Rinjani National Park Authority imposes a strict daily quota on the number of trekkers allowed on the mountain. Booking early ensures your trekking agency can secure your official park entrance tickets before they sell out.

When booking, you will usually have two options:

Private Package: This is exclusively for you and your travel companions. You get your own dedicated guide and porters, allowing you to hike at your own pace. It is more expensive but offers a highly personalized experience.

Shared (Join-in) Package: You will be grouped with other travelers (usually 4 to 10 people per group). This is a more budget-friendly option and a great way to meet fellow hikers, but you will need to adapt to the general pace of the group.

To secure your booking and allow the agency to purchase your national park tickets, a deposit is typically required (usually around 30% to 40% of the total cost).

Deposits are generally paid via international transfer methods like Wise, PayPal, Western Union, or direct bank transfer.

The remaining balance is almost always paid in cash (Indonesian Rupiah) upon your arrival in Lombok or during your pre-trek briefing.

Because the Mount Rinjani National Park uses an online e-ticketing system, trekking operators must register you officially. To complete your booking, you will need to provide:

Your full name (as it appears on your passport).

Your passport number and a photo of your passport information page.

Your gender, nationality, and date of birth.

Your arrival details in Lombok (flight number or fast boat schedule) for hotel pick-up arrangements.

Policies vary slightly between different trekking operators, but generally:

Deposits are non-refundable if you cancel the trip, as the money is immediately used to secure non-refundable park tickets and reserve guides/porters.

Rescheduling is often permitted if you give sufficient notice (usually at least 7 to 14 days before the trek), subject to ticket availability on your new dates. (Always double-check the specific cancellation terms with your chosen trekking agency before sending a deposit).

Mount Rinjani is a challenging volcano to climb, and it should not be underestimated.

The Summit Push: The final ascent to the 3,726m peak is particularly grueling due to steep inclines, high altitude, and loose volcanic scree (where you often slide back one step for every two steps forward).

Crater Rim Treks: The shorter treks to the crater rim are still physically demanding but are much more manageable for people with an average to good level of fitness.

The ideal time to trek is during Indonesia's dry season, which runs from April to November. During these months, the trails are safer, and the weather is generally clear, offering the best views.

Important Note: The Mount Rinjani National Park is officially closed every year from January to March due to heavy rainfall, dangerous trail conditions, and ecological recovery.

No, you do not need to bring your own camping gear or food if you book a package. The trekking company will provide all necessary tents, sleeping bags, mattresses, and cooking equipment. The guide and porters will also prepare all your daily meals (breakfast, lunch, and dinner) on the mountain. You only need to carry a small daypack with your personal items, such as a camera, headlamp, extra clothing, and snacks.
