The Rocktown Hiking Trail, located in the western part of Lucas Park, is a 3-mile loop trail that begins and ends at the parking lot access area on the east side of Rocktown.  The 305-acre area has been registered as a Kansas Natural and Scientific Area by the Kansas Biological Survey in agreement with the U.S. Army Corps of Engineers.  The area is characterized by rolling hills with shallow sandy soils, steep slopes along the valley wall, and rock outcroppings.  Massive red sandstone rock formations rise 15 to 30 feet above the ground and give the visual impression of a city skyline, hence the name Rocktown.  Brochures for this self-guided hike are available at the trail entrance.
