Yes they are open if it rains , we actually came while it was raining as well. There is more water inside which is kind of cool! When you get to the end of the cave you will see what I'm talking about. Have fun!
The tour is about 30 to 45 min I think. Wasn't keeping track of time bit it didn't feel too short or too long.
It's about 45 to an hour. And I second what Jessica stated...It's even better when it's raining.
Also how long is the tour?
