Gunung (Mount) Agung is the highest mountain on Bali. It is a (currently) dormant volcano.
There are two recognised trails for Gunung Agung. One starts from Pura Besakih (near Besakih village), the holiest temple in Bali, which leads to the very top of the peak (3048 metres by GPS, although most maps show a greater elevation of approximately 3142 metres)and offers a 360 degree field of panorama including views as far as Gunung Rinjani on Lombok to the east and the volcanoes of east Java to the west.
The other trail is from Pura Pasar Agung (near Selat village) and is shorter by comparison (approximately 4 hours) but only leads to a lower point on the crater rim which is actually a few hundreds meter below the true summit of the mountain and offers a more restricted 180 degree of view.
There is no path along the crater rim to connect the 2 trails at their respective high points and so ascent and descent has to be by the same route.
Gunung Agung is called the 'Mother Mountain' of Bali and is highly sacred to the Balinese people. There is a major temple complex on its slopes at Besakih. Its last major eruption was in 1963 killing more than a thousand people.
The ascent of the mountain is not technically difficult especially in the dry season although it is significantly more challenging in the rainy season when the trail is wet and slippery both in the jungle section and on the rocky slabby section beneath the summit ridge and much greater care is needed on some sections of the trail. The weather can also be more hostile and unpredictable.
Regardless of season, a good degree of stamina and fitness is required to make the 5 to 8 hour ascent from Besakih and especially if it is done as one haul rather than with an overnight stopover at a campsite/bivouac three quarters way up the mountain.
It is recommended to use a guide (there are plenty available in Besakih and Selat) although it can be climbed without. No trekking permit or fee is required to be paid to the authorities to climb the mountain.
