Jenny Lake is a tent only campground located right on the shore of Jenny Lake in Grand Teton National Park. During peak season (June-Aug) this campsite fills by 9AM but we arrived at 4PM and there were still spots available. From this campsite the main hiking hub of Grand Teton is within walking distance as well as the camp store as visitors center. Since it was still early in the season a lot of the trails were closed to snow but the open trails still made for an amazing experience.
Sage Creek is a primitive campground located in the interior of The Badlands National Park. The campsites are first come first serve and are free to use. However there are only two pit toilets for the entire camp and no water is available so bring your own is a must. Buffalo continually frequent the campground so storing food away a night is a must. There are also limited trails in the badlands but sage creek campground is a great starting point for backcountry trips but following sage creek into the interior.
