If you are a tent camper, something you quickly realize when traveling in this are of Wyoming is that not all campgrounds are created equally. There are so many options yet many of them are in high risk areas for bears and because of that you are somewhat limited when it comes to forest sites. That was the case when entering ThreeMile Campground!
I was very interested in this campground for a variety of reasons including large shaded sites, river access and proximity to Yellowstone's Eastern entrance. However as excited as I was I was quickly disappointed as I pulled into camp, got out of my car to pay for a site and discovered I would not be able to stay at this location. I am not opposed to car camping in an area, but at this location they do not allow car camping either only hard sided RVs or Vans. I was so upset!!
I toured the camp despite not being able to stay and just as I had imagined the sites are very nice. The tables are sturdy and mostly shaded. there are bear boxes at each site in addition to fire rings and the spacing for most vehicles is decent.
I spoke to a ranger in the area and he mentioned the threat of moving bears was very high at this campground hence the restrictions and while I understood it was still upsetting. I went on to explore a bit more and noticed that there are several sites along the shore where you can leave your site and walk right into the water. Others were on the land side and offered seclusion with trees and bushes.
Bathrooms here are only vaults and there is no electricity or water provided so you will want to bring everything with you should you stay here. Prices seemed very reasonable at $15 for standard sites and $30 for double with a discount given to senior access pass holders.
I noticed a few posted rules for the campground including quiet time hours for not only generators but also music, a point which the ranger reiterated to me because many people come here and blast music during summer months.
