The Rock Park

The Rock Park is home to Castle Rock's iconic namesake - a dramatic rhyolite butte that has served as a landmark for travelers since the days of the Old West. Rising 180 feet from its base, this natural monument gave the town its name and remains the most recognizable symbol of the community. **The Hike** A well-maintained trail leads from the parking area to the base of the rock formation. The moderate 0.5-mile hike features interpretive signs explaining the geological and cultural significance of this natural monument. While climbing the rock itself is prohibited to protect the formation, the views from the base are spectacular. **History** • Native American tribes used the rock as a navigation landmark for centuries • Early settlers and railroad travelers relied on it for orientation • The Denver & Rio Grande Railroad established a station here in 1871 • The town incorporated in 1881, taking its name from this iconic formation **Geology** The rock is composed of rhyolite, an ignite volcanic rock formed millions of years ago. The unique composition and erosion patterns have created the distinctive shape that defines Castle Rock's skyline. **Starlighting** Each November, a large star is lit atop the rock during the annual Starlighting celebration, marking the beginning of the holiday season. The star has been a tradition since 1936.
