Kalimantan, the Indonesian part of Borneo, is home to one of the world’s most incredible and endangered species—the Bornean orangutan (Pongo pygmaeus). These magnificent primates are best observed in their natural habitat, swinging through the dense rainforests of Kalimantan. However, to make the most of your visit and witness orangutans in optimal conditions, it is essential to plan your trip carefully. In this article, we explore the best time to visit orangutans in Kalimantan, ensuring an unforgettable wildlife experience.
However, there are notable challenges:
Muddy Trails and Flooding: National parks experience heavy rainfall, making trekking more difficult.
Lower Orangutan Visibility: Orangutans may spread out as fruit is available across vast areas, reducing their concentration in certain spots.
Unpredictable Boat Travel: Rising river levels can make boat trips slower or sometimes impassable.
1. Dry Season (June to October) – The Best Time to Visit
The dry season in Kalimantan, which spans from June to October, is widely regarded as the best time to visit orangutans in the wild. Here’s why:
– Better Accessibility: The trails in national parks like Tanjung Puting, Sebangau, and Kutai are more navigable, reducing the chances of rain-induced delays.
– Ideal for River Cruises: Many orangutan sanctuaries, especially Tanjung Puting National Park, require river travel by klotok boats. During the dry season, water levels are stable, ensuring a smooth journey.
2. Wet Season (November to May) – A Challenging but Unique Experience
While the wet season from November to May is not the most recommended time for visiting, it does have some unique advantages:
– Fewer Tourists: If you prefer solitude, the wet season sees fewer visitors, allowing for a more exclusive wildlife experience.
– Lush Greenery: The rainforest is at its most vibrant, with thick vegetation and a burst of life.
– Unique Photography Opportunities: Dramatic clouds, misty mornings, and rain-drenched foliage provide stunning photography conditions.
