The Castle Rock Chamber of Commerce’s “Lighting of the Star” has been a favorite community event shared by residents dating back to 1936. The same spirit of volunteerism, generosity and love of tradition exists today as Castle Rock businesses and residents prepare to kick off and celebrate the holiday season! For many, this is a sacred family tradition, not to be missed! Ongoing Festivities around the square and at Festival Park from 2 pm to 6 pm. Actual Star lighting ceremony will begin at 5 pm, with the star lit at approximately 5:30 pm.
