AAA Editor Notes
Crystal Onyx Cave, off I-65 exit 53, then 2 mi. e. on SR 90 to 425 Prewitts Knob Rd., contains spectacular formations viewable from well-lit trails.
Note: Full mobility is required for this 1.5-hour, half-mile guided tour; there are approximately 100 steps. A light jacket is recommended since the cave is a constant 56-degrees Fahrenheit.
Guided tours are available. Picnicking is permitted. Time: Allow 1 hour, 30 minutes minimum.
