Guadalupe Mountains National Park treats visitors to a glimpse at millions of years of history, holding in its stony ridges and canyons a massive fossilized reef, the traces of Paleozoic plant and animal life, documents of human civilizations and conflicts and an astounding diversity of surviving wildlife. 80 miles of trails lead hikers or horseback riders providing their own stock through secluded switchbacks, rugged wilderness and sylvan canyons.
