A friend of mine highlighted to me that 27 of the world's highest volcanoes are located in South America and have an elevation greater than 6,000 m
(Wikipedia; a good listing of mountains and volcanoes can be found on here)
In Peru, Sabancaya is currently one of the highest active volcanoes in the world at an altitude of 5,976 m ASL. But that can certainly change quickly. As I will not climb that high, I looked into guided tours to lower volcanoes such as the Villarrica <2'860 m ASL>. An active volcano in Chile with a permanent lava lake in the crater. The last eruption was in 2015.

I have listed the top 15 that are "next" to my planned tour.
I'm also thinking about visiting the El Tatio thermal area in the Atacama Desert. The Lascar <5'592 m ASL> in northern Chile is an active volcano that heats this highest thermal area in the world😎
Láscar contains six overlapping summit craters and two major complexes. Frequent small-to-moderate explosive eruptions have been recorded since the mid-19th century. The latest eruption included an explosion, ash plumes, and thermal activity during December 2022 through February 2023
