Diablo Lanes is a true Concord vestige. Fun in the good old American tradition, this is a destination for people of all ages. Bowling leagues come in the evening, and joining is encouraged. Senior leagues come in the daytime. They run many weekly specials with themes such as Monday Night Madness and Friday Night Frenzy. All ages are welcome in the evening. Simply ask a bowling center employee about joining a team. USBC is the national governing body of the sport of bowling. Joining a league helps preserve the sport.
