Fodor's Review

Multicolor travertine terraces formed by slowly escaping hot mineral water mark this unusual geological formation. You can explore the terraces via an elaborate network of boardwalks, the best of which is the Lower Terrace Interpretive Trail. If you head uphill from Liberty Cap, at the area's northern end, in an hour you'll pass bright and ornately terraced Minerva Spring. Along the way you might spot elk grazing 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 takes an hour, works especially well if you can park a second vehicle at the foot of Lower Terrace. There are many steps on the lower terrace boardwalks, so plan to take your time there. The boardwalk routes change as the terraces move and grow. A map and brochure at the boardwalk trailhead has a self-guided tour.
