Mammoth Cave: Just south of Panguitch Lake on Scenic Byway 143 is the Mammoth Creek road. Turn south on this road and go approximately 7 miles. Signs will lead you east on a dirt road toward Mammoth Cave. Visitors enjoy going into this lava tube that has formed a long cave. Bring a flashlight.
Cascade Falls: Follow the Mammoth Creek road south from Scenic Byway 143 to Highway 14. Turn west (right) and go to Navajo Lake. At Navajo Lake turn left off of 14 and follow the first left fork in the road (1/4 mile) then follow the road as it bends to the right (south). Travel approximately two miles on dirt road to parking area for Cascade Falls. Follow the trail west below the rim about .5 miles to the falls. This is where water drains from Navajo Lake out the side of the mountain and makes a cascading waterfall down the hillside red hued limestone formations.
