Plan on 90 minutes for Cave of the Winds.

About 90 minutes, give or take 15.

The guided tour itself runs 45–60 minutes. The bottleneck is the elevator—especially when crowds show up. You’ll wait 5–15 minutes to go down, then again on the way up. Add in grabbing and returning those sandals (they make you wear them to protect the cave floor) and you’re looking at about an hour and a half total.

If you’re booking tickets, give yourself at least two hours so you’re not stressing. The cave is dark and cool and genuinely cool. Don’t rush it.
