Limekiln State Park, State park in Monterey County, United States

Limekiln State Park is a 711-acre California state park on the Big Sur coast, 2 miles south of Lucia on Highway 1. It holds four iron and stone lime kilns from an 1887–1890 operation, a redwood forest, a beach at Rockland Cove, and the 100-foot Limekiln Falls. A 0.5-mile trail from the highway reaches the kilns, stone walls and bridge abutments.

In the late 1880s, a company operated four kilns here to process limestone for San Francisco's construction boom. The site was later abandoned, but the kiln structures remain as reminders of that industrial period.

The old limestone kilns on the site tell visitors about 19th-century industrial work and how people extracted minerals from this coastal area. They show what daily labor looked like for workers in early California.

The park offers camping spots under redwoods and with ocean views, along with hiking trails to waterfalls and creek areas. Visitors should wear sturdy shoes since trails can be steep and slippery, especially after rain.

The 100-foot Limekiln Falls drops over a rock face on the east fork of Limekiln Creek, reached by a trail from the highway. The falls do not run all year; flow depends on rainfall and dwindles in the dry season. The park's 711 acres also hold a beach and a redwood forest that regrew after the kilns stopped burning.
