There is only one trailhead, so in and out is the way to trek it normally. This is a hiking and backpacking trail that is quite long, so make sure you bring plenty of supplies. This trail goes through some very different elevations, and that means that some parts of the trail could be very different from other parts of it. Being 14.2 miles long; it's longer than many trails. This trek should take you about 2 days, so better have big a backpack to fit all the stuff you need. Halape Trail has a total elevation difference of 2,922 feet, and that is higher than average.
