Lake Toba Caldera Loop
Enter via Berastagi and exit via Parapat, looping around the western shore of Lake Toba to Samosir Island to see waterfalls and viewpoints.
Perfect for a short holiday flying in from Singapore or Malaysia. Charter a car for the entire trip, crossing onto the island via the Tele mountain road and bridge, and exiting by ferry to avoid backtracking. Day 2 has a longer drive but features the most concentrated scenery. This route skips the rainforest and orangutans to focus on volcanic lake landscapes and Batak villages.
During the rainy season, the Tele mountain road and viewpoints are prone to fog and landslides; allow extra buffer time in your schedule.
