My friends are staying there now and they said they paid $8 day walk in the caverns and $18 for the night tour. They drive down the street because it’s hot right now but everything is accessible walking they said.

Separate admission fee. You could walk to bike to cave tour, but its over a mile. Probably 1.5.

Yes! It’s a small campground. Easy to walk everywhere. We didn’t have bikes but I’m sure they’ll be fine
