Internet says there’s no admission, so I must have misremembered that part. We did look around the gift shop a bit.

My wife and I found ourselves near Mt. Rushmore by happenstance durin a road trip several years back. We knew the history, but stopped in to see it for ourselves. We found it to be extremely shitty and underwhelming. The natural area behind the monument was incredible, and I absolutely understand why the indigenous people believed this place to be sacred, but the front was small, tacky, and depressing. I wish I could refund our admission and give it to some chill natives at a gas station instead.
