Morning fog lifts off the Landak River and the jungle exhales: leaves drip, insects begin their chorus and a distant guttural call hints at orangutans deeper in the forest. This six-day circuit out of Medan leads from the riverside village of Bukit Lawang into Gunung Leuser National Park — nights in basic guesthouses and an overnight bamboo-frame camp, days on steep jungle trails and through shallow river crossings.
