I just recently discovered Tripadvisor so I am writing all these reviews from memory.
I went to the Chiricahua national monument with my colleagues for a research retreat at the Southwest Research Station in 2009.This place is an inactive volcanic range in an expansive dessert region in AZ.
There are several trails for day-hiking and most of them give you a beautiful view of the scenery. The surroundings are beautiful and you will come across birds and white tailed deer throughout your trip. The Chiricahua Mountains are an ecological junction for plants and animals from four ecosystems; the Rocky Mountains, Mexico’s Sierra Madre , the Sonoran and Chihuahuan Deserts (I found this to be cool)
The national monument is well maintained and the staff there is very friendly.
If you are anywhere nearby, do visit this place.
