A Climb throughout the night up Mount Merapi, the very active volcano that dominates the Javanese Landscape and can be seen from Neighboring Borobudur and Yogyakarta
nice views of volcanoes.in S and SE Asia it's the custom to climb mountains at night,esp.holy ones like sripada(Adam Peak)in srilanka.To see the sunrise they say. almost compulsory as you mentioned!
