Highlights of Sumatra

After rainforest walks, the trip heads uphill to Berastagi in the volcanic highlands, where the cooler air is a welcome break and the town’s fruit and vegetable market offers a lively portrait of daily life. An early start and climb up Mount Sibayak takes in steaming sulphur vents and views across volcanic peaks. Beyond that lies Lake Toba, the world’s largest volcanic lake, where Samosir Island introduces the traditions and architecture of the Batak people.

The final day includes a return to Medan with a walking tour of the Kesawan district. Throughout the week, the pace varies—early mornings, demanding walks and slower cultural visits—and the trip balances wildlife, local projects and traditional villages, handled by Explore Worldwide’s knowledgeable guides with an eye for detail and context.

These are the places the trip visits, in order. Explore Worldwide publishes the day-by-day itinerary on its own site.
