This great outdoors trail has only one trailhead, so you'll be backcountry hiking it in and back out. Now this hiking trail is pretty long, so do pack enough food to last the whole trip. This great outdoors trail has a total elevation difference of 4,737 feet which is a higher than average number. Being 20.4 miles long; it's considered a longer backcountry trek. This region does get very dry sometimes, so do check for current fire restrictions before you go if you plan to bring a stove or make a camp fire. Different parts of Sawtooth Pass Trail are at very different elevations which of course means you need to be prepared for different conditions on different parts of the great outdoors hiking trail. This backcountry trek should take you about 3 days, so it's a great thing if your backpack is big enough to do the job.
