Hartmann Inline Rink: North Boulder's Nonprofit Outdoor Roller Hockey Rink on 28th Street
Hartmann Inline Rink: A Nonprofit Rink Sitting Right on the 80301/80304 Line
The mailing address at 4800 28th Street carries a Boulder, CO 80301 zip, per the site's own directory listing on AboutBoulder.com — not 80304 — but it sits close enough to North Boulder's own zip line that it belongs in the neighborhood's recreation map rather than outside it. What's actually on that lot is Hartmann Inline Rink, a one-floor outdoor roller hockey rink that has run as a nonprofit since 1999. Per the rink's own mission page, Hartmann Rink is organized as a 501(c)3 volunteer organization whose mission is to make inline hockey available to anyone of any age or gender in Boulder County — a stated mission the rink has carried since before most of North Boulder's newer nature-play parks existed.
Where is it? 4800 28th St, Boulder, CO 80301 — on 28th Street a short stretch north of Valmont Road, close enough to the 80304 boundary that a North Boulder household is nearer to this rink than a straight zip-code filter would suggest.
Founded in 1999, Hartmann Rink is, per the facility's directory profile on RinkTime, a one-floor outdoor roller skating rink that operates year-round rather than shutting down for winter — worth flagging for anyone who assumes an uncovered rink means a summer-only season. Twenty-seven years is a long run for a single-sport nonprofit facility, and it puts Hartmann Rink's founding closer to Boulder's mid-1990s recreation build-out than to the current decade — a piece of neighborhood infrastructure that predates most of what's gotten written up on this site so far.
Leagues, Drop-In Hockey, and Youth Clinics: What's Actually Happening on the Floor
Per a Boulder-area skating roundup from Travel Boulder, Hartmann Rink runs two adult leagues spanning beginner to advanced play, alongside free drop-in games open to all skill levels. The same source lists all-level pick-up games at 6:30 p.m. on Sundays and advanced-level pickup at 6:30 p.m. on Tuesdays — though it flags, correctly, that start times shift throughout the year, so anyone planning a first visit should confirm the current session schedule directly with the rink rather than treating a published time as fixed months later.
Beyond the adult side, RinkTime's listing for the rink describes a full youth program: roller hockey camps and clinics built around fundamentals drills under supervision, plus roller hockey leagues split into youth and adult divisions. Lessons run the same beginner-to-advanced spread as the leagues — beginning skaters get basics instruction, while more advanced players work on form, technique, and specific goals with an instructor. For a North Boulder family with no prior hockey background, that beginner track is the practical detail that matters most: a kid can start with zero skating experience, work through a clinic, and land in an actual youth league on the same rink without switching facilities.
The rink isn't exclusively a hockey venue, either. General public roller-skating sessions, open to all ages, run alongside the hockey programming, and the facility keeps a snack bar on site for anyone spending an afternoon there rather than dropping in for a single session. Current public-session times aren't posted at a fixed weekly slot — RinkTime's listing notes the schedule changes and directs visitors to call the rink directly at (303) 545-5226 to confirm what's on the floor on a given day, the same number the rink's own directory listings point to for league inquiries, lesson bookings, and event planning.
A Volunteer-Run 501(c)3: The Boulder Roller Hockey Club's Code of Conduct
Hartmann Rink is operated by the Boulder Roller Hockey Club, and the club's own mission page is specific about what kind of hockey it's built to run: recreational, not contact. The rink's published Code of Conduct — the document every participant agrees to before skating — states outright that Hartmann Inline Rink is a recreational hockey rink, meaning there is no checking, and that fighting carries a strict zero-tolerance policy resulting in a minimum one-game suspension. Skating under the influence of drugs or alcohol is explicitly forbidden, and the code asks players to respect officials' judgment, be on time for games, and remember — in its own stated language — that the contest is only a game, "not a matter of life or death for the athlete, the coach, the team, the spectator or the community."
That code is worth reading past the boilerplate, because it reflects a different orientation than a lot of adult recreational hockey carries elsewhere: a rink built and run by volunteers, governed as a 501(c)3, explicitly organized around access — "anyone of any age or gender" — rather than around competitive tiering or a franchise structure. For a North Boulder resident weighing whether a 27-year-old outdoor rink on the edge of the neighborhood is worth a first visit, that governance detail is as much a part of the picture as the schedule: this isn't a corporate rink chain, it's a nonprofit club still running on the same volunteer structure it launched with in 1999, funded and staffed by the people who show up to skate.
Skate Fitness Classes and the Gateway Park Fun Center Next Door
The rink's floor has hosted more than league play and drop-in hockey over the years. Travel Boulder's skating roundup also lists skate-fitness classes held at Hartmann Inline Rink — Wednesday-evening sessions built around interval training, bodyweight exercises, and skating drills rather than hockey itself, run as a separate program on the same rented floor. It's a reminder that an outdoor inline rink like this one doubles as general-purpose skating infrastructure for the neighborhood, not solely a hockey venue — the same surface that hosts a Tuesday-night advanced pickup game also hosts a Wednesday fitness class built for an entirely different kind of skater.
The 4800 28th Street lot itself is shared ground. Travel Boulder's own listing locates Hartmann Rink as sitting "at Gateway Fun Park" — the family entertainment complex whose attractions occupy the same parcel as the rink. The two are separate operations with separate purposes, and Gateway Park Fun Center's own draw is covered on its own terms elsewhere on this site rather than repeated here; the detail worth knowing in this piece is simply that a family stopping at one is standing a short walk from the other, and a visit to either is realistically a visit to both.

Hartmann Rink won't turn up on a strict 80304 zip-code filter, and that's exactly why it earns a place here: the rink sits close enough to the North Boulder line that most 80304 households are nearer to a 27-year-old nonprofit hockey facility than a zip search alone would show. Whether the draw is a beginner adult league, a Sunday drop-in game, a youth clinic, or an open-air public skate on a rink that's stayed volunteer-run since 1999, the practical move is the same — call ahead to confirm the current schedule, since sessions shift through the year, and treat the northern stretch of 28th Street as part of the neighborhood's recreation map, not outside it.
