Stairway to Heaven:
The 250 steps of the stairway to heaven can be a bit difficult to ascend as they are steep, covered in volcanic ash and at the higher elevation the oxygen levels are lower and can be mixed with the odor of sulphur. The climb up will reward you with an amazing view inside the volcano.
