In 1926, during the violent eruption of Mt. Batur, the original village of Batur, at the southern foot of the mountain, was totally destroyed. The villagers, unharmed but homeless, moved up onto the high ridge overlooking their original home, and began the task of rebuilding their temple, Pura Ulun Danu. Work on this temple is still underway, and they are creating one of the most impressive temples on the islands. Its stark meru towers stand out against the backdrop of the smoking volcano.
Batur is the most active volcano on the popular tourist island of Bali and one of Inondesia’s more active ones. During the past centuries, Batur has had a number of small eruptions every few years.
The volcano is located at the center of two concentric calderas NW of Agung volcano. The outer 10 x 13.5 km wide caldera was formed during eruption of the Bali (or Ubud) Ignimbrite about 29,300 years ago and now contains a caldera lake on its SE side, opposite the satellitic cone of 2152-m-high Gunung Abang, the topographic high of the Batur complex.
The inner 6.4 x 9.4 km wide caldera was formed about 20,150 years ago during eruption of the Gunungkawi Ignimbrite. The SE wall of the inner caldera lies beneath Lake Batur; Batur cone has been constructed within the inner caldera to a height above the outer caldera rim. The 1717-m-high Batur stratovolcano has produced vents over much of the inner caldera, but a NE-SW fissure system has localized the Batur I, II, and III craters along the summit ridge.
After climbing the mountain, to see the sunrise proceed by bus to the Natural Hot Springs at Toya Bungkah, set right on the shores of Lake Batur. Enjoy bathing in the hot mineral waters (from 32 to 390 Celcius) and have lunch right here at the lakeside restaurant
