This study found that hikers were willing to travel on average over four hours to visit the Grandfather Mountain Wilderness Preserve and its trail system, and did so five times per year. Although this study is old, it is one of the few with values specifically for a day of hiking, particularly in the southern U.S.
This study found that surveys that directly extrapolate the number of times an individual person visits a trail to the general population will significantly overstate the future trail use. Care must be taken to account for the differences between those interviewed at the trailhead and the rest of the population.
This study found that trail users are willing to incur greater expenses and travel further to use rural trails, and spend more time on those trails while they are there, indicating these trails are enjoyed by both locals and non-locals. Urban trails, on the other hand, are mainly a resource for local residents, and are used much more frequently and for shorter periods of times.
