Trekking in this southern region of Sumatra offers an adventure through lowland rainforests teeming with rich biodiversity.
Trekking in Bukit Barisan Selatan demands physical and mental preparedness due to its often wet, muddy terrain and high humidity. However, all these challenges are well worth the rare opportunity to explore the habitats of the giant Rafflesia arnoldii and Amorphophallus titanum (corpse flower).

The trail then changes drastically into a steep ascent through a dense forest known as the “Dinding Lemari” (Cupboard Wall) due to its extreme incline.

Best Time for Sumatra Trekking
Knowing the best time to visit is crucial for your safety and comfort during your trekking in Sumatra and adventure trip. Generally speaking, Sumatra’s tropical climate is divided into a dry season and a rainy season, which directly affect trail conditions on the ground.
The Best Time for Orangutan Trekking (Bukit Lawang & Ketambe
May through September is the best time to visit, as this is the dry season. During these months, rainfall is very low, so the hiking trails in the forest are neither slippery nor muddy. In addition, the forest trees are usually heavy with fruit during this season. This causes Sumatran orangutans to frequently come down to lower branches in search of food, making them easier to spot.
The Best Time to Hike Volcanoes (Kerinci, Sibayak, Marapi, Dempo)
Meanwhile, the safest time to climb the mountain is during the dry season, from June to August. Clear skies will help you navigate the rugged trails with ease while enjoying a perfect sunrise. Avoid climbing during the peak of the rainy season, from October to February. The bad weather during those months is extremely dangerous, as it increases the risk of landslides, storms, falling trees, and thick fog that can obscure the main trail.
