🌧️ Rain or Shine — We’re Open for Tours! 🌧️
A little rain can’t stop us! Whether the sun is shining or the clouds are rolling in, our tours are still running. Come experience history and adventure no matter the weather — the underground is always damp, cool, and waiting to be explored.
Don’t let a few raindrops keep you inside. Grab your jacket, bring the family, and make some memories with us today! 🪨 ⛏️
📅 Open for tours Wednesday through Sunday
Tours starting at 11 and running hourly until 3.
Doors open at 10.
