Millions of years of erosion carved the dramatic bluffs, spires and pinnacles of this stepped, 100-foot contour that is one of Kansas' most interesting geological features.
Begin this trip with a drive to the overlook above the cliffs for a birds-eye view before setting out on foot. The parking area about half-way up this mile-long bluff system is a great place to start; the central section of the bluff is packed with arches, tunnels and eroded gullies to explore. This route loops south first, climbing user-created trails to the bluff top and following its edge. .4 mile in, the trail dips to the road—be sure to explore the two large crags on its south side—before tuning north under the cliffs.
This route follows the road for .2 miles and tucks back into the maze of cliffs to bypass the parking area and continue north past a large fin formation and through an open field toward the grayish mounds just west of Castle Rock.
Castle Rock itself towers over 60 feet high and marks the northern end of this loop. After cruising it’s base, follow the dirt road, or the small singletrack trail alongside it, .6 miles back to the parking area.

Peek over the rocky edges at the towering sand and limestone cliffs below. It is more difficult to work your way back down to the bottom of the cliffs from here, so trace the singletrack along the ridge heading south.
