There are a number of trails that humans can embark on at the Gaudalupe Mountains National Park but pets aren't permitted on any them at this particular National Park. While that may seem like a bummer at first, there is a good reason for that restriction; the Guadalupe Mountain trails are home to a number of wildlife species that would either attempt to prey on your pet (such as mountain lions and coyotes) or who could potentially be preyed on by your dog. Fret not, however, as the campgrounds and picnic areas surrounding the park are open to dogs. Some portions of the nearby Lincoln National Forest permit pets, though caution is strongly advised for those who go there.
While the rules and restrictions that prevent pets from partaking in most of what the Guadalupe Mountains has to offer may seem unfair, they were put in place for the benefit of yourself, your dog, and the native wildlife of the area. Don't get us wrong, the Guadalupe Mountains National Park is still a fantastic place to visit on your own or with a group of friends or family members - it's just not the most dog-friendly National Park one could visit due to the wide range of predatory animals that call this park home. It's still possible to have fun with your dog in this area, but you'll need to be extra responsible and extra creative to do so.
