Pre-dawn hike up an active volcano inside the Batur caldera for sunrise over the clouds
Mount Batur rises from the middle of a vast volcanic caldera in Bali's north-east highlands, with the crescent of Lake Batur curving along its foot. The classic way to experience it is to start walking by torchlight in the early hours, reach the summit area in time for first light and watch the sun come up behind the peaks to the east while the caldera fills with cloud.
The climb is steep in places, on loose volcanic gravel, but it is short enough for reasonably fit beginners. On the way down, daylight reveals the black lava fields left by 20th-century eruptions, steam vents near the crater and the villages and farms of Kintamani spread around the caldera.
Batur sits inside two nested calderas formed by enormous eruptions tens of thousands of years ago; UNESCO dates the outer caldera to about 29,000 years ago and the inner one to about 20,000 years ago. The volcano has erupted many times since records began, and the dark lava fields of the 1960s remain clearly visible from the Kintamani rim. Its most recent eruption was in 2000.
In September 2012 the caldera became Indonesia's first member of UNESCO's Global Geoparks Network, and it was designated a UNESCO Global Geopark in 2015. The geopark covers 370.5 square kilometres and includes fifteen villages in Kintamani district, and the government has promoted community-based ecotourism here since the listing.
The villages around the caldera grow vegetables, citrus and coffee on the volcanic soils, and fish farms dot the lake. Lake Batur is sacred in Balinese Hinduism: the Supreme Water Temple Pura Ulun Danu Batur on the caldera rim is part of the UNESCO-listed subak landscape, because the lake is regarded as a source of water for farmland across the island. Trekking in the area is organised largely by local guides from the surrounding villages.
Most treks are arranged as packages with hotel pick-up from Ubud or south Bali in the early hours, a local guide, a torch and breakfast at the top. The ascent usually takes around two hours from the trailhead, and some guides cook eggs in volcanic steam near the crater. Once the sun is up, many groups walk part of the crater rim before descending.
After the trek, soak tired legs in one of the hot spring pools beside Lake Batur, or take a jeep tour across the lava fields. Those who prefer not to climb can still enjoy the view from the restaurants and viewpoints along the caldera rim at Kintamani.
The dry season from about April to October gives the best chance of a clear sunrise and firm footing. In the wet months, roughly November to March, cloud and rain can hide the view and make the trail slippery. Temperatures near the summit before dawn can be cold at any time of year, so bring warm layers. Volcanic activity can lead authorities to restrict access, so check the current status before booking.

Hot spring pools line the shore of Lake Batur at Toya Bungkah, close to the trailheads. The Kintamani caldera rim has restaurants with views of the volcano and lake, and Pura Ulun Danu Batur stands on the rim at Batur village. Ubud is roughly an hour to an hour and a half away by road, and most trekkers travel with the transport included in their tour.
