Lintong is southwest of Lake Toba, high on a plateau with a notable diversity of tree ferns. This richly volcanic region is known for fertile soils, myriad microclimates created by small valleys, and much sought-after Blue Batak coffee. Around 70,000 years ago, a massive super-volcano erupted in Lintong. The eruption was the biggest on earth in the last 25 million years, and left many lakes and incredibly fertile soil in its wake. In fact, the soil is so rich that the Bataknese say you can put a chair in the ground, and it will become a table.
