It is a wonderful campground, and a good place for staging your visit to YNP. The restroom facilities were appreciated, as they had regular toilets instead of vault toilets. The only amenity was potable water, and that was appreciated. The construction trucks are very loud, and could better serve the campground guests if they didn't use jake brakes, and did not operate during the quiet hours the campground has to abide by.

I enjoyed my stay at the campground very much! My only complaint is the faucet in the Women's Restroom at Site 74. It splashed a lot everywhere and was a big pain to use.

I really love this campsite. Nice landscape surrounding with quick access to the Terrances and hiking! This is my 2nd time camping at this campground. I will say that you can sometimes hear cars driving but it was not a problem for us. Also not for showering you will want to help back into town or to the south end of the park as there are no showers here.

Fantastic host/volunteers. Bathrooms and facilities were well kept and very clean.

Please go back to first come first serve basis rather than advance reservations. We saw that a lot of sites were no-shows (or cut their reservations short) during our stay.

If absolutely necessary, reservations should be made by campsite type, rather than specific sites. This, coming from someone with a background in reservations. We spent a lot of time checking in and checking out of three (yes, three) different sites during our short six night stay when we could've been out and about exploring.

The reservations, both here and in Grand Teton, put enormous time constraints on our trip. In the past, we've had the opportunity to travel more organically, with an open and flexible schedule. This is especially important when it comes to things like avoiding crowds and inclement weather.

Happy to be able to stay here, as we got a last minute reservation due to a cancellation. Would recommend posting late arrival info at the entrance, as we didn’t know if we needed to pick up info like at Madison, and spent time looking. The view was lovely and it was great to be close to the Lamar Valley.
