Kerinci is more active than most Indonesian volcanoes, with nearly annual phreatic eruptions. Kerinci last erupted in 2004, and continues to spew clouds of sulphurous smoke, with plumes reaching as high as 1,000 m (3,281 ft) above the summit. While there is farmland in the area, and a tea plantation on its southern slope, Kerinci, being located in an Indonesian national park, and perhaps out of respect for its frequent growlings as well, sits in an area that is sparsely populated by Indonesian population-density standards.
Kerinci can be climbed from the village of Kersik Tuo, 6 or 7 hours away from Padang by car or bus. The climb and descent normally takes 3 days and 2 nights, when choosing to go all the way to the summit. Climbers may also choose to go up only as far as Camp 2 or 2.5, skipping the summit attempt which is a night climb, taking 2 days and 1 night instead.
Kerinci's terrain consists of thick jungle, and can get muddy and slippery even if there are only mild drizzles, which may occur occasionally even during the dry season. To climb the volcano a guide is needed, as there have been rare cases of people disappearing after attempting to trek alone.
The mountain has 15 lakes which the biggest are Kerinci Lake and Gunung Tujuh Lake. The 4,200-hectare of Kerinci Lake lies at a height of 650 meters, is the host of annual July Kerinci Lake Festival. While Gunung Tujuh Lake means Seven Mountains Lake which there are 7 peaks surrounding the lake. It is also the highest lake in Southeast Asia at 1,996 meters.
