They will be open even if it rains.
We are open if it rains. The only thing that stops tours is lightning, and in that case we try to wait it out and then resume tours when it is safe. Feel free to bring umbrellas, and we do sell ponchos as well. I hope the weather does not/did not deter you.
You can bring your own umbrella etc. They also sell poncho's if you'd like to purchase them instead of using a ☂️.
