Rancho Santa Margarita Lake is the defining feature of RSM’s identity—a scenic community lake at the city’s heart, surrounded by parks, trails, and the Town Center, and the gathering place for RSM’s most significant community events. The RSM Annual Tree Lighting is the city’s signature December tradition, bringing families together at the lake area for a celebration that reflects RSM’s tight-knit character. The Home Decorating Contest is RSM’s holiday pride tradition—a city-run competition that reflects how seriously Rancho Santa Margarita takes its holiday season. Together, the lake, tree lighting, and decorating contest define a December calendar built around genuine community investment.
