Celebrate Father’s Day with an underground adventure! Bring Dad to Cave of the Mounds for a day he won’t forget: exploring the stunning natural beauty of the cave after enjoying lemonade and snacks in the Visitor Center.

Each father will receive a take-home geode to remember the day. Whether you’re spending the day with Dad or Grandpa—or another father figure!—it’s the perfect way to create memories and enjoy nature, above and below ground.
