I have heard about volcano in books and I do not think many of us will have a chance to see a volcano in active during our lifetime unless you go on globe trotting with meticulous planning and see countries at quite pace which i have made it as a hobby.I do not worry about the breaks in my backpacking trips as I have our loved ones to take care and enjoy the family life too.But my daughter and her friends heard about this Ijen volcano in Indonesia and decided to climb and see this Marvel .
