Donaldson Cave (Spring Mill State Park) offers compact limestone passages, drip-worn walls and a moody, low-light interior ideal for texture and abstract shots. Photograph the entrance alcove, stalactite details and the transition from bright forest to dim cave. Check park hours and guided-tour schedules; tours may limit tripods/flash—visit weekdays or off-season for fewer people. Parking at the park lot; wear sturdy shoes for slippery boardwalks. Best light contrast at mid-morning when sunlight
