What does backcountry mean to you? Is it the areas that are only accessible by hiking or backpacking for several miles? Or, must you venture out on remote, super gnarly, high-clearance-only dirt roads?
By definition, a backcountry area is a geographical region that is isolated, remote, undeveloped, and difficult to access. So the answers to the above questions are yes… but… there are plenty of backcountry areas in Utah that are fairly easy to access. And, thanks to the influence of social media, they are heavily visited by people who may not necessarily have the knowledge, skills, understanding, gear, etc. to be safe.
