Multicolor travertine terraces formed by slowly escaping hot mineral water mark this unusual geological formation. It constantly changes as a result of shifts in water flow. You can explore the terraces via an elaborate network of boardwalks. The best is the Lower Terrace Interpretive Trail. If you start at Liberty Cap, at the area's north end, and head uphill on the boardwalks, you'll pass bright and ornately terraced Minerva Spring. It's about an hour walk. Along the way you may spy elk, as they graze nearby. Alternatively, you can drive up to the Lower Terrace Overlook on Upper Terrace Drive and take the boardwalks down past New Blue Springs to the Lower Terrace. This route, which also take an hour, works especially well if you can park a second vehicle at the foot of Lower Terrace.
