Air Terjun Sipiso-Piso North Sumatra

These narrow but impressive falls cascade 120m down to the northern end of Danau Toba, 24km from Kabanjahe and about 300m from the main road. It's worth a photo stop en route between Berastagi and Toba, or as part of a tour, but not necessarily as a trip in its own right. There's a panoramic viewpoint at the car park, otherwise it's a 45-minute-return walk down the stairs for a closer look.Take the Bintang Karo bus from Berastagi (8000Rp, one hour).
