This isn't just any volcano; it's famous for its massive eruption in 1991, one of the largest of the 20th century. It significantly altered the surrounding landscape. Now, it's a popular hiking destination, home to a beautiful crater lake. Think of it as a sleeping giant that woke up and then took a nap.
