If you don't mind walking barefoot on monkey crap, fearless monkeys, and hauling yourself up hundreds of steps, climbing Mount Popa might be for you.
Actually, the monkeys only bother if you have food, the monkey crap is dried and the steps are low height and steepness. The climb is not too difficult.
You will be rewarded for your efforts with bizarre shrines along the way, and an awesome view at the top.
