Yellowstone Backcountry

Tom Hunter · 10/21/2026

For someone experiencing Yellowstone's backcountry for the first time, I'd recommend a 2-day, 1-night backpacking trip along Slough Creek, in the park's spectacular northeastern corner. It's a fantastic introduction to wilderness backpacking: wide-open meadows, a winding trout stream, rugged mountain scenery, and the possibility of spotting bison, elk, moose, and other wildlife. The trail follows an old wagon route. After an uphill start, it descends into a beautiful valley and continues toward the upper meadows. Campsite 2S1 is approximately 4.9 miles from the trailhead, including its spur trail. What makes this trip special is the balance: it's long enough to feel like a genuine wilderness adventure, but short enough that a reasonably fit first-timer can enjoy the experience without making mileage the entire focus. What you'll need A comfortable backpack, tent, sleeping pad, and warm sleeping bag Rain gear and insulating layers, even in August Water filter, 2–3 liters of carrying capacity, stove, and easy meals Bear spray for each person, accessible and practiced An approved hard-sided bear-resistant container or at least 35 feet of rope for the campsite food pole Offline topographic map, headlamp, first-aid kit, and ideally a satellite messenger Important: Yellowstone is serious grizzly country. For a first overnight, go with experienced companions, preferably in a group of three or more. Keep your camp's sleeping area separated from cooking and food storage areas, follow all campsite rules, and check for bear activity or closures before leaving. Permits and reservations You must reserve or obtain a designated backcountry campsite permit. The park currently lists a $10 reservation fee plus $5 per person per night, separate from park entrance fees. For a summer 2027 trip, verify the new season's reservation schedule before planning your date
