Enjoy the dappled shade and seating at the Sempervirens arbor. Review the panel and upcoming events in the display case to learn about the land trust that started Castle Rock State Park in 1968 and built the Robert C. Kirkwood Entrance to improve access and the quality of visitor experience. 

On weekends State Park interpreters often wheel an interactive interpretive cart onto the adjacent welcome plaza, full of tactile exhibits and audio-visual information.
