I'm leading an overnight kayak trip in Grand Teton Nat. Park in two weeks. String & Leigh Lake. A backcountry permit is required and I made my reservation back in January. I believe they do hold a few of the campsite permits each day for walk-up customers, so you could get lucky and grab one? I'm not sure if that's the way it works in Yellowstone. I'm super stoked about this trip because the videos I've seen of Leigh Lake are absolutely gorgeous. Fingers crossed for good weather.
