We didn't see any of the buffalo, but plenty of antelope, prairie dogs, and burros. The sheep and goats were no where to be found either.

If you want to see some Bison well.. This is where you'll find them. Also proghorns and prairie dogs are a very common sight. Missed the burros though! I drove the loop twice: once around 10AM and once around 5PM. I would recommend when sunny.

Stayed in Custer for 3 days to see the area as well as Mt. Rushmore. Took the Iron Mountain Road and also decided to do the Wildlife Loop Road as part of it. Glad we did. Beautiful drive with multiple animals spotted: Elk/Deer/Eagles/Bison. Worth the 1 hour detour.

This was my favorite part of our trip. We were lucky enough so witness the rangers rounding up some of the buffalo one day, we saw many white tail and mule deer, pronghorn antelope, prairie dogs, donkeys and a couple of coyotes.

This herd of burro were a bit off the road at first. We pulled over as did several other cars. As we waited they... More 

Check in at the visitor's center to find out where the bison are. Take some of the off roads you might see more. Make sure have gas in your car. Bring apples for the wild burros

Taking the Wildlife Loop Road is the highlight of any visit to Custer State Park. Bison, pronghorn, mooching wild donkeys, prairie dogs and other animals are visible just by driving by. But be sure and stop, because otherwise you won't hear the sounds made by the animals.

The is the best place to see wild buffalo in South Dakota. We saw buffalo, pronghorns, prairie dogs, wild burros and deer. It's a nice drive, but make sure you give yourself plenty of time to stop and enjoy the animals.
