bit.ly/NOLSpackrafting. Packrafting is at the forefront of Alaskan exploration and NOLS is right there with it. Since their inception, these single-person inflatable rafts (weighing around four pounds each) have opened up some of the world's most remote country that would be otherwise inaccessible to overland travel. With this equipment and the help of experienced instructor teams, you will navigate the rivers of the eastern Alaska Range and the Talkeetna Mountains that would otherwise be obstacles on a traditional backpacking course.
