Every year, thousands of people from the Tenggerese community of East Java make their way on a pilgrimage to Mount Bromo, an active crater, to ask for blessings and another year with no eruptions. The festival is known as the Kasada Ceremony, and holds deep spiritual meaning for the community who still hold on to their ancient Hindu beliefs. Once the crowds reach the crater, they throw in offerings which include fruits, vegetables, flowers and even cattle to the God of the Mountain in gratitude for blessings. Mount Bromo is quite a distance from many a hotel in di Surakarta, so it is advised to try and organise your journey ahead. However, in general, any good hotel like a Alila Solo Hotel in Indonesia, can help to arrange a trip for you, so it's not that difficult.
