Only 1h30 driving from the village of San Pedro de Quemes, you'll be driven to the foot of the crater at 4300m from where a trail leads up to the active crater at 4980m. You will find yourself surrounded by Yellow Sulfur. When the sulfur clouds and the wind allow it, you can go further up to the highest point at 5176m. 

 

This volcano takes half a day (getting up early) and is ideal to acclimatize before going higher.
