Dixie National Forest — the largest national forest in the state (1,900,000 acres!) is mostly high altitude evergreen forest, with lots of hunting, fishing, camping, hiking, climbing, and even spelunking possibilities
The part of Utah known as Dixie is the southwestern corner of the state. It bears this incongruous name (more commonly associated with the South region of the United States, far to the southeast of Utah) because early settlers were successful in practicing some of the same agriculture as in the southeastern United States. Historically it has been sparsely populated, but the growing popularity of St. George as both a retirement community and a jumping-off point for outdoor recreation is increasing the population rapidly.
