The total elevation difference for this great outdoors trail is 1,437 feet, and that is about average. You should count on this walk taking about 8 hours, but of course some folks walk a bit slower and some a bit faster. Being 9.2 miles long; it's longer than many trails. Fire Creek Way has only one trailhead, so you'll be backpacking it in and back out. You spend the whole hike in roughly the same elevation zone, so you get pretty much the same conditions along the whole trail. Now this trail is pretty long, so make sure you bring plenty of supplies.
