The Colorado Mammoth: Boulder's Home Pro Lacrosse Team
If you follow lacrosse in Boulder County, the Colorado Mammoth should be on your radar. They're a 30-minute drive down US-36, they play one of the most exciting sports you'll watch live, and they represent the highest level of box lacrosse in the world.
Who Are the Mammoth?
The Colorado Mammoth are a franchise in the National Lacrosse League (NLL) — the premier professional indoor lacrosse league in North America. The NLL has teams across the US and Canada, and the Mammoth are one of the league's marquee franchises with multiple championships in their history.
They play box lacrosse — the indoor version of the game, played in an enclosed arena on turf laid over a hockey rink. It's faster, more physical, and louder than the outdoor game. If you've only seen field lacrosse, a Mammoth game will change your perspective on how exciting lacrosse can be.
Ball Arena, Denver
The Mammoth play at Ball Arena in downtown Denver — the same building where the Colorado Avalanche and Denver Nuggets play. It holds roughly 20,000 fans for lacrosse, and on a sold-out night the atmosphere is electric.
Parking and transit options from Boulder include the RTD Flatiron Flyer (FF1) express bus, which connects Boulder to Denver Union Station and downtown Denver. It's one of the easiest ways to get to a Mammoth game without driving.
The NLL Season
The NLL season runs from December through May, with playoff rounds in the spring. The Mammoth play home games at Ball Arena throughout that stretch, typically on Friday or Saturday nights.

Why Bring Your Players to a Game
Watching the Mammoth is genuinely useful for any lacrosse player in Boulder County:
- Box lacrosse develops field players — the skills on display (quick releases, off-hand finishing, crease play) translate directly to the outdoor game
- The speed of the game is unlike anything at the youth or high school level — watching pros play at full pace raises a player's sense of what's possible
- It's affordable — Mammoth tickets are reasonably priced compared to other pro sports in Denver, and family packages are available
