The best time to go to Malinau is during the dry season, which typically runs from June to October.
During these months, you'll experience more consistent sunny weather and lower humidity, making it ideal for outdoor activities like exploring the Kayan Mentarang National Park. The rivers are also generally calmer and at a more predictable level, which is beneficial for boat travel, a primary mode of transport in the region. This period is particularly good for adventurers and nature enthusiasts.
The dry season also makes it easier to visit local villages and experience cultural events without the interruption of heavy rainfall.
