What to Pack for Sumatra
Sumatra is one of the last places on Earth to see wild orangutans, Sumatran tigers, and rhinos. The rainforest is hot, humid, and full of leeches, so packing light, breathable, quick-dry clothing is essential. You will get wet, whether from rain, river crossings, or sheer sweat. Serious insect protection is critical, and leech socks are a genuine game-changer for jungle treks.
