Mist Trail is a one trailhead backpacking and hiking trail, so in and out is the way to backcountry hike it normally. Mist Trail is 2.8 miles long it's shorter than many hiking and backpacking trails. This region does get very dry sometimes, so make sure you check current conditions and fire restrictions with local forest authorities before you head out. Mist Trail has a total elevation difference of 1,214 feet which is an average number. You spend the whole backcountry walk in roughly the same elevation zone, so you get pretty much the same conditions along the whole hiking and backpacking trail. You should count on this backcountry walk taking about 2.5 hours, but you never know stuff could go wrong and you could get stuck so be prepared for that. Mist Trail is not that long but it's always pleasant to bring some emergency supplies, you never know what could happen.
