We provide a fun and safe opportunity for recreational adult soccer in Marin. Participation is open to women at least 18 years old and to men at least 30 years old. The MCSL 11v11 games are on Saturdays with Spring and Fall season "round-robin" schedules. Games are played at various turf fields throughout Marin, including Redwood High School, Red Hill Field, Tamalpais High School, Novato High School, and others. There are currently ten teams in the League. Click here to inquire about joining a team.

The MCSL encourages friendly competition. No standings are kept, and there are no trophies for winning. Good Sportsmanship Awards are given to three teams each season. The primary motivation for our players is the camaraderie of the beautiful game. We play using the FIFA Laws of the Game with modifications related to substitutions, number of men and women players, safety (no slide tackles or hard challenges), and maintaining good relations (no dogs at the fields)

In the summer and winter, MCSL offers small-sided pickup-style games using small pop-up goals with no refs nor goalies, where the teams are formed at the field.  The "8v8" sessions are open to players that meet the age requirements listed above. 

In December 2025, the league offers its first official season of the Legends Division.  The format is similar to the 8v8s, but using slightly larger goals and open to women at least 40 years old and men at least 50 years old.
