A dawn fog lifts off the Bahorok River as a local guide leads the group into the lowland rainforest near Bukit Lawang. Orangutan calls thread through the canopy; the river itself seems to urge the trekker forward, pushing cool mist across the trail. This program threads jungle trekking and wildlife viewing with highland volcanoes and the broad surface of Lake Toba for a compact, varied circuit across North Sumatra.
