Toba Caldera Geopark(new 2020)

Located on Sumatra Island, Toba Caldera was formed by a super-volcano eruption 74,000 years ago. The water-filled basin of the caldera is the largest volcanic lake in Indonesia and is situated 904 metres above sea level. The large Samosir Island rises up from the lake set amidst wave hills, mountains and plains.  The creation of the caldera exposed basement rocks, enabling scientists to study what was once part of the mega continent Gondwana. Home to the Batak Toba, Simalungun, Karo and Pakpak people, the area has a rich cultural heritage which can be explored by visiting traditional houses and museums in the Geopark.
