Bali's highest and most revered mountain, Gunung Agung is an imposing peak seen from most of south and east Bali, although it's often obscured by cloud and mist. Many sources say it's 3142m high, but some say it lost its summit in the 1963 eruption. The summit is an oval crater, about 700m across, with its highest point on the western edge above Besakih.
As it's the spiritual centre of Bali, traditional houses are laid out on an axis in line with Agung and many locals always know where they are in relation to the peak, which is thought to house ancestral spirits. Climbing the mountain takes you through verdant forest in the clouds and rewards with sweeping (dawn) views. More than 3000 tourists make the ascent each year.
