Green Cabin Flat Campground is underdeveloped camping, making this spot the place for the more adventurous at heart. It’s worth the price of not having hot showers—there isn’t a lot of traffic rolling through these grounds, making your experience secluded. The campground is located along the roaring Kings River. Nearby trails in the Giant Sequoia National Monument are absolutely killer for biking, horseback riding and just good ol’ footin’ it through unending groves, wrapping around rushing rivers and ascending mountains. If whitewater rafting is on your bucket list, take up the opportunity to cruise down to Pine Flat Reservoir and dip your toes in Class III rapids.
