The crown jewel of Mount Batur's geography is its caldera, a massive depression formed by the collapse of a magma chamber. This colossal crater measures approximately 10 kilometers (6.2 miles) in diameter and 700 meters (2,300 feet) deep.
Difficulty: Moderately difficult
Duration: 2 hours
The most popular starting point, this route involves a steep ascent for a few hours. This well-maintained trail is shorter and easier compared to the other routes you might take, but it's also the most crowded.
Difficulty: Challenging
Duration: 3 hours
This is a trek that’ll start from the Pura Jati temple. This is a great starting point for if you want to views of the Mount Batur lake as you’re going up!
Difficulty: Challenging
Duration: 4 hours
Serongga Village is one of the many that dot Mount Batur. This one will be a challenging trek, and you will experience a whole other side of Mount Batur (literally!); the steeper and rockier side.
A caldera is a massive depression formed by the collapse of a magma chamber roof. When a volcano erupts and expels a large amount of magma, the ground above the chamber can no longer support its own weight and caves in. This creates a large, often circular depression that can be several kilometers wide.
Mount Batur's caldera is a staggering 10 kilometers (6.2 miles) in diameter and roughly 700 meters (2,300 feet) deep. Imagine a giant crater big enough to swallow a small city!
Nestled within the caldera is the beautiful Lake Batur, a crescent-shaped lake with a surface area of approximately 16 square kilometers (6.2 square miles). The lake's formation is a combination of factors. Rainwater collects in the depression, and volcanic activity can contribute to the water level through hydrothermal vents and steam condensation.
Yes, Mount Batur is considered an active volcano. Its most recent eruption occurred in 1999-2000, spewing lava and ash. While not constantly erupting, it's a reminder of the island's volcanic origins.
Mount Batur is a stratovolcano, also known as a composite volcano. These conical mountains are built layer by layer from lava flows, ash, and volcanic debris ejected during numerous eruptions.
Yes! It’s active, but it’s not spewing ash or lava, so it’s perfectly safe. You can always check before you leave, as authorities strictly monitor the activity of this volcano
Mount Batur comprises two volcanic calderas, a volcanic landscape complete with caldera walls, cones and craters, geothermal phenomena such as fumaroles and hot springs, a lake, lava flows, pyroclastic flows and tephra. At the top, you can see steam rising from the ground!
Not red hot lava, but you can see dried up (and cooled) dark lava on the sides of the slopes and molten lava rocks dot the pathways in villages.
Not since the year 2000. And it doesn’t look like it might erupt any time soon. You can always check beforehand.
It’s usually chilly year round until the sunrise, but particularly in the winter months between December and March. Temperatures drop down to about 14 degree celsius.
It’ll likely be quite dusty if you’re visiting in the dry seasons. Would highly recommend carrying a mask in case of allergies! If you’re visiting after it rains, you’ll find that the paths are muddier.
