Buffalo Gap National Grassland in South Dakota is the second largest national grassland in the U.S. at nearly 600,000 acres. The grassland area features both prairie and badlands.

We camped at a dispersed site in Buffalo Gap National Grassland in 2018 while visiting the nearby Badlands National Park as the campgrounds within Badlands were all full. The landscape was beautiful and wide open, though we nearly ended up stuck after three days of steady rain.
