Founded in 2005, the Colorado Indoor Lacrosse League (CILL) is the longest running league in the Rocky Mountain region. As the only truly competitive mens box lacrosse played in Colorado, the CILL remains focused on offering an authentic box experience playing under National Lacrosse League rules.

 

We are proud to bring you our Spring season starting February 2nd. The CILL plays at Foothills Fieldhouse, the practice facility for the NLL’s Colorado Mammoth. Please see our registration page for more details.
