Let me start by saying I hated the overall vibe in Grand Teton NP. People were selfish, pushy, rude. Everything was set up there for the most selfish to win. We came here after a stay at Yellowstone and thought we would try our hand at a small first-come-first-serve campground. We woke up at like 2 in the morning and got to a wait and frenzy kind of weirdness where people just wasted gas driving in circles to rush to the first spot they could find someone leaving. I wanted nothing to do with that so we left and started looking at other options. We pulled into Gros Ventre and they still had spots, thank goodness. 

The staff were incredibly friendly and helpful. Our site was awesome with a path back to a quieter area for the tent. A staffer told us to watch for a moose cow and baby that had been oft seen lately, but I never did see them. Excpet I MIGHT have seen moose legs through the open flap of our tent haha.

You can walk to the river and there are endless stones to practice skipping. There's a better local vibe in this campground that is way better than the rest of the park. The bathrooms are nice - flush toilets and running water. No showers. A flushing drain for your dish water. Bear boxes for each site.
