The best time to visit Tangkahan is during the dry season, which typically runs from May to September.During these months, you'll experience less rainfall and more sunshine, making it ideal for outdoor activities like jungle trekking and river tubing. The trails are less muddy, and the rivers are calmer, ensuring a more comfortable and enjoyable experience when interacting with the elephants or exploring the surrounding nature.Travellers looking for an active holiday will find the dry season particularly suitable. With clear skies and pleasant temperatures, you can fully enjoy the treks through the Gunung Leuser National Park and the various elephant-related programmes without the interruption of heavy downpours.
