The best time to trek Mount Rinjani is during the dry season, which typically lasts from April to October. Here’s why:

2. Trekking Season: April to June
The Perfect Time to Trek Mount Rinjani
The months of April to June are particularly ideal for trekking, especially if you’re looking for favorable weather and fewer crowds compared to the busier months of July and August. Here’s why this period is perfect:
Transition from the Rainy Season
• April: Marks the start of the dry season. While there may still be occasional light rain, the trails begin to dry out, and the vegetation looks lush and green after the rainy season.
• May: Features more stable weather, with clear skies and pleasant temperatures. This month is ideal for both beginner and experienced trekkers.
• June: Offers some of the best trekking conditions—dry trails, comfortable temperatures, and excellent visibility for enjoying the stunning scenery.
Fewer Crowds
Compared to the busier months of July and August, the trails are quieter during this period, providing a more peaceful and personal trekking experience.
Stunning Scenery
The landscapes are breathtaking, with vibrant greenery and flowing waterfalls along the trekking routes. The crater lake, Segara Anak, is particularly mesmerizing during this time.
Comfortable Temperatures
Daytime temperatures are warm but not overly hot, ensuring a comfortable trekking experience. Nights can be cool, especially at higher altitudes, so bringing warm clothing is essential.
By choosing to trek Mount Rinjani between April and June, you can enjoy the perfect balance of favorable weather, fewer trekkers, and stunning natural beauty, making it an ideal time for an unforgettable adventure.
3. Peak Trekking Season: July and August
July and August are the most popular months for trekking due to consistently favorable weather conditions. However, this is also the peak season, meaning the trails can be crowded with other trekkers. If you prefer a quieter experience, consider trekking in April, May, September, or October.
4. Avoid the Rainy Season: November to December
Trekking during the rainy season (November to December) is still possible, but it requires extra preparation due to rain and strong winds. While this period is not recommended for trekking, if it’s the only time available, ensure you bring high-quality trekking gear to protect yourself from the rain and wind. Be extra cautious, as heavy rain can make the trails slippery and dangerous.
Trail Closures
Mount Rinjani is usually closed for trekking from January to the end of May due to extreme weather conditions and to allow the trails to recover.
