The first clue of how large this campground is, is during check in. A whole row of agent's are checking campers in. Once you enter your loop however things become quiet. I stayed in a tent camping loop, where almost all campers were sleeping in their vehicles like me. The problem is, tent sites have on-loop parking, there is no driveway, so it was literally a string of parallel parked rigs on both sides of the road, and the road was sloped. Each site had a private bear locker for personal storage. Bathrooms have nice, enclosed large kitchen sink for meal clean up to prevent bear attracting smells at your site. This is a high altitude camp and was very cold (high 20s) at night. Great base for explaining Canyon country and Hayden Valley. Nearby lodge, shopping and groceries.
