Thinking about signing your kid up for lacrosse? Boulder County has well-established youth programs for both boys and girls, and getting started is easier than most parents expect. USA Lacrosse — the sport's national governing body — runs a "Where to Play" directory and a Get Started guide, but locally you have two anchor clubs that handle most of the county's youth players. Here's how it works.

The Local Clubs

Two sister organizations cover the bulk of recreational and competitive youth lacrosse in the Boulder area, both serving grades 1 through 8 at all experience levels:

Both explicitly welcome beginners, so your child does not need any prior experience to join. Registration for the main spring season typically opens early in the calendar year.

The Season Calendar

Lacrosse in Colorado is built around a spring core, but the local clubs keep players busy year-round:

  • Spring — the primary season; league play and games, usually with registration opening in January
  • Summer — day camps (Boulder Valley Lacrosse runs a multi-day camp at CU Boulder) and tournaments
  • Fall — skills sessions and shorter fall leagues
  • Winter — indoor sessions that borrow from the box game and keep stick skills sharp through the off-season

For a younger player, starting in a spring league is the natural on-ramp; the fall and winter options are good ways to keep developing once they're hooked.

Age and Level Breakdown

Youth lacrosse is organized into two-year age bands so kids play with and against others at a similar stage. USA Lacrosse structures youth play around divisions commonly labeled U9, U11, U13, and U15 (the "U" is the age a player is under). The local clubs map that onto grades, serving roughly grades 1 through 8 before players move on to school teams:

  • U9 (about grades 1–3) — the introduction: fundamentals, small-sided games, and lots of stick time, with simplified rules and limited or no body contact on the boys' side
  • U11 (about grades 3–5) — fuller field play and the real rules start to take hold
  • U13 (about grades 5–7) — more positional play, faster pace, and a step up in competition
  • U15 / middle school (about grades 7–8) — the bridge to high school lacrosse

From there the path continues into CHSAA high school lacrosse, where boys and girls compete in separate spring programs. Knowing your child's band helps you read a club's registration page, since seasons and practice loads scale up with age.

What Gear Does My Kid Need?

For beginners, most programs keep the equipment requirement light to start. Boys' players generally need a helmet, gloves, shoulder and arm pads, a stick, and a mouthguard. Girls' players need protective eyewear (goggles), a mouthguard, and a stick, with a deeper gear list only at higher levels.

Because boys' and girls' lacrosse are different games with different equipment, double-check your specific club's gear list before buying — and read our breakdown of men's vs women's lacrosse differences so you understand why the kits differ. Many families buy a starter stick first and add pads as a player commits to the sport. USA Lacrosse publishes current equipment standards if you want to confirm what's sanctioned.

What It Costs

Budgeting for a first season comes down to three buckets, and only the first is fixed. Sanctioned youth programs require a USA Lacrosse membership for every player — currently $35 a year — which also provides the insurance coverage that member clubs carry. That's separate from, and on top of, the club's own registration fee.

Club registration fees vary by program, season, and age level, so check the current price on your club's registration page rather than budgeting from a number you heard secondhand. Equipment is the most variable cost: a beginner stick is the cheapest way in, and many programs keep early-level gear requirements light, so you can start small and add pads as your player commits rather than buying a full kit on day one. If cost is a barrier, ask the club directly — many run gear-swap events or have loaner equipment, and USA Lacrosse offers scholarships and grants aimed at lowering the entry cost for new players.

Rec vs. Competitive: How to Choose

Most local clubs offer two tracks, and picking the right one matters more than picking the "best" team. Recreational (or house) lacrosse is lower commitment and lower cost: local games, shorter travel, and a focus on learning the sport and having fun. Competitive (travel or select) lacrosse means more practices, tournament play that can involve weekend travel, tryouts, and a bigger time and money commitment.

For a brand-new player, the recreational track is almost always the right first step — it builds fundamentals and confidence without overloading a kid (or a family calendar) before anyone knows whether the sport sticks. If your player falls for it and wants more reps against stronger competition, the competitive track is there to move up into. The clubs above run both, so you're not locked in by your first choice; talk to a coach about which fits your child's age, experience, and how much your family wants to travel.

What to Expect as a Parent

Youth lacrosse is welcoming and fast to pick up. Early-level practices focus on fundamentals — cradling, passing, catching, and ground balls — before games get competitive. Expect a time commitment of a couple of practices plus a game most weeks during the spring season.

The county's clubs are volunteer-supported, so there are usually opportunities to help with the team if you want to be involved beyond the sideline. If your player sticks with it, the path continues into middle-school and then CHSAA high school lacrosse, where boys and girls compete in separate spring programs.

Getting Started

Once your child is signed up, the best next step is to go watch some lacrosse together. A Colorado Mammoth game at Ball Arena or a local high school match is the fastest way to get a new player excited about the sport.
