Can You Climb Mount Rinjani in December? Is the trail still open? Is it safe? Does the rainy season make the climb too risky?
Mount Rinjani has long been a dream destination for hikers from around the world. Its volcanic landscape, dramatic ridgelines, and the iconic Segara Anak crater lake offer a trekking experience that is both challenging and unforgettable. But not every traveler can visit during the typical “ideal” season. Many international tourists only get their long holiday in late December.
Rumors about Rinjani being closed during the rainy season often cause confusion. Some people assume the mountain is entirely off-limits during December, while others hear that it is still accessible. This article is meant to give you a clear, comprehensive, and honest explanation, based on seasonal patterns in Lombok, official park operations, and real trekking considerations.
Before you finalize your travel plans, let’s go through everything you need to know.
Can You Climb Mount Rinjani in December?
Yes, you can climb Mount Rinjani in December.
December is typically the final month of the open trekking season, right before the park officially closes for safety reasons when the rainy season reaches its peak. Rinjani is still open for hiking and camping activities through December until the first week of January, provided that weather conditions remain stable and the authorities deem the trails safe.
This means that if December is the only time you can travel, you still have a chance to experience the trek legally and safely.
Indonesia generally enters the rainy season in November–December, but Lombok is slightly different. The peak of the rainy season in Lombok often arrives later—usually in early to mid-January. December serves as a transition period: you may experience occasional rainfall, but it rarely rains all day.
In other words, Rinjani remains accessible, but you must carry realistic expectations and a flexible mindset.

Pros and Cons of Climbing Mount Rinjani in December
Climbing in December is not simply a matter of whether the trail is open. You need to understand the full context so you can make wise decisions. The rainy season comes with its own charm—and its challenges.
Below is a balanced explanation of the advantages and drawbacks.
Pros of Climbing Mount Rinjani in December
1. Fewer Crowds, More Serenity
If you dislike trekking in long lines of hikers, December may surprise you. Compared to the busy months of June–August, December offers a calmer and more peaceful atmosphere. You can walk at your own pace, take photos without waiting for space, and enjoy the mountain in a more personal way.
2. Cooler Temperatures and Greener Scenery
With occasional rain, the vegetation becomes fresher and more vibrant. The air feels cleaner, the trees look greener, and the entire landscape appears more alive. Combined with cooler temperatures, the trek can feel more comfortable compared to the dry and dusty trails of mid-year.
3. A More Authentic Nature Experience
There is something special about trekking during the early rainy season. Mist that moves slowly across the ridge, the smell of wet earth, and the atmosphere after a light drizzle add depth to your hiking experience. Many photographers also love December for its dramatic and moody sky.
4. Weather Can Still Be Good
Because Lombok’s rainy season starts later than most regions in Indonesia, you still have a fair chance to get clear skies. Many hikers successfully reach the summit in December with stunning sunrise views.
Cons of Hiking in This Month
1. Rain Can Come Unexpectedly
Rain in December is unpredictable. It may not rain all day, but sudden downpours are common. When rain hits the open areas of the trail—especially the sandy sections near the summit—your pace may slow down significantly.
2. Stronger Winds at Higher Altitudes
As the rainy season approaches, wind conditions can become unstable. Some ridges are more exposed, and gusts of wind can add difficulty to your climb.
3. Slippery Trails, Muddy Ground
Trails that are normally easy become challenging when wet. Wet rocks, muddy slopes, and slippery roots require much more focus and balance. You must be extra careful with your steps.
4. You Need More Complete Gear
December is not a month for minimal packing. Waterproof equipment becomes essential: dry bags, rain jackets, reliable trekking shoes, and warm layers. Without proper gear, even a short drizzle can make the hike uncomfortable.
5. Possible Sudden Trail Closure
Although the trail is officially open, the National Park Authority may close sections temporarily if weather conditions become dangerous. This is not common, but it is still a possibility you should be aware of.
