In order to participate in this beginner-friendly backpacking adventure, you need to be fit and have a bit of hiking experience. Still, no previous backpacking experience is necessary to take part in this adventure. Expect to spend up to 6 hours per day walking or hiking (up to 10 miles and 1000 ft elevation change) while carrying daypacks or backpacks with water, snacks and camping gear. Keep in mind, Yellowstone has very extreme weather. It can be warm and dry in the day, but cool in the evenings. Recently, daily highs have been reaching well beyond historical averages.
