This is a fun classic to start off our date ideas list. Pack a picnic to bring to Cave of the Mounds. Either sit on the grass or at a picnic table. Enjoy the sunshine and nature around you. Take your time. After you eat, grab some tickets to the Cave. It may be a wait, so hike the nature trails. If you want a more casual stroll, walk along the karst trail. If you want it a tad bit harder but not too difficult, walk down the Oak Valley Loop. Finally, head back to the gift shop where you can take a breath before cooling off in the cave.
