You can watch wild bison from your car at the Arsenal refuge

One of the easiest places to see wild bison in Colorado is not in the mountains. It is at the Rocky Mountain Arsenal National Wildlife Refuge in Commerce City, a short drive from downtown Denver.

The refuge keeps a herd of bison that were brought in to help manage the native prairie. You can view them along the refuge’s Wildlife Drive, an auto-tour loop of about eleven miles that takes under an hour at an easy pace. Along the way you may also see deer, coyotes, raptors, and busy prairie-dog towns. Entry is free.

There is one rule that matters for your safety: when you are near the bison, stay in your vehicle. Bison are large, fast wild animals, and they are not tame despite how calm they look grazing. The refuge also asks visitors to stay on marked trails and keep out of the lakes. Pets are generally not allowed on the refuge, with service animals the exception — and if a pet rides along while you do the Wildlife Drive, it has to stay inside your vehicle the whole time.

This makes for a calm, low-effort outing, good for kids, older visitors, or anyone who wants real wildlife without a hike. Just treat it as the wild place it is.
