Denver Last-Minute Camps: What Parents Can Still Do in May
Summer camp registration closed months ago. Now it's May or June, and you need a plan.
It's May. You just realized summer starts in four weeks and you have exactly zero camps registered. Here's the honest picture: Denver's 232 tracked summer camp programs fill in waves, with the most popular programs closing in January and February. But our data shows that roughly 40% of Denver metro camps still have open sessions by late May, primarily in the rec center, arts, and specialty categories. You have more options than you think.
Denver Summer Camps 2026 Complete Guide
Key Takeaways

- Colorado Academy Summer at 3800 S Pierce St runs 730 total sessions, one of the highest session counts in the city, and typically has late availability.
- Arts and STEM programs like School of Rock Denver ($250-$450/week) and MindCraft Makerspace ($300-$500/week) use rolling enrollment.
- Denver Zoo camps at $85/week are the best budget option with late openings still possible.

What are the realistic last-minute camp options in Denver?
When we tracked registration windows across 232 Denver metro programs for 2026, the pattern was consistent: overnight camps and museum programs close first, rec centers and specialty studios close last. The good news for May registrants is that the programs with the most session inventory tend to close last. Colorado Academy Summer at 3800 S Pierce St runs 730 sessions across the summer. At that volume, late openings are not a fluke, they're structural.
The broad categories still worth calling in May are municipal recreation centers, arts studios with rolling weekly enrollment, STEM programs that run independent weekly cohorts, and newer programs that launched with unfilled capacity. Knowing which specific camps are in each category saves you two hours of phone calls.
Citation Capsule: Denver's 232 summer camp programs range from $65/week at Camp Apex to $1,995/week at JCC Ranch Camp, with the median program falling between $300 and $500/week. Programs with the highest session counts, including Colorado Academy Summer (730 sessions) and TPRD (410 sessions), structurally retain more late-summer availability than boutique programs with 40-60 total sessions (ProjectKids, 2026).
Which Denver rec centers and city programs still have spots in May?
According to Denver Parks and Recreation, the city's MY Denver program spans 37 recreation center locations across Denver's neighborhoods. The city-run system operates on a different enrollment model than private camps. Sessions roll on a weekly basis, capacity is larger, and the registration window stays open much longer.
Denver Parks and Recreation programs run $150-$350/week across the metro. These are general activity camps: swimming, sports, crafts, field trips. Not specialized, but reliable and well-run. The southeast Denver rec centers tend to have more availability than the Capitol Hill and Highlands locations.
TPRD at 16799 E. Lake Ave runs sports and athletics camps at $200-$400/week. They show 410 sessions in our data, with all 410 listed as full sessions. The high session count means cancellation openings surface regularly. Call them directly on Monday mornings.
Camp Apex at 13150 W. 72nd Ave deserves a mention here. At $65-$85/week, it's one of the lowest-cost structured programs in the Denver metro. With 50 sessions and a flexible enrollment approach, this is worth a direct call if you're in the northwest suburbs.
Free and Low-Cost Denver Summer Camps
Citation Capsule: Denver's municipal recreation system covers 37 rec center locations citywide, with summer camp programming typically available through rolling weekly registration. City-run programs priced at $150-$350/week represent some of the last programs to fill, because their capacity is larger than specialty studios and their enrollment windows stay open into the summer (Denver Parks & Recreation, 2026).
What are the best arts and specialty camps still open in late May?
Arts and creative programs are the second-best category for last-minute registrations. Most of them run weekly cohorts that are independent of each other. If week three is full, week six might be open. That's different from a 6-week overnight program where weeks one through six are a single enrollment.
School of Rock Denver at 560 S Holly St runs camps at $250-$450/week with 100 sessions. They cover rock band, songwriting, and performance across age groups 7-17. Call their studio directly. The later summer weeks (late July, August) open up as school-year families start consolidating commitments.
Pop Punk Camp at 2030 S. Colorado Blvd charges $425/week for 100 sessions. Similar rolling-enrollment model. If your kid plays guitar, bass, or drums and you've missed the specialized programs, this is one of the better late-registration options in South Denver.
Dance Institute Denver at 10515 E 40th Ave runs 100 sessions at $225/week. That price point is strong for a specialty dance program. East Denver location works well for Aurora-adjacent families.
Colorado Ballet Academy Armstrong Center for Dance runs camps at $200/week. Eighty sessions total, with summer camps spanning multiple dance styles. Their youngest sessions (ages 3-4) tend to have the most late availability.
Lighthousewriters at 3844 York St in Denver's Whittier neighborhood runs creative writing camps at $270/week. Sixty sessions, small cohorts. If you have a kid who loves writing and you've missed the museum programs, this is worth calling.
House of Rock Summer Day Camps at 71 E Yale Ave runs $250-$450/week. So does Swallow Hill Music at the same Yale Ave address. Both music-focused, both use rolling enrollment, and both tend to retain late availability in the July-August stretch.
Which STEM and tech camps take late registrations?
STEM camps span a wide price range in Denver, from $279/week at CodeNinjas to $1,079/week at iD Tech. The premium programs close in January. But the mid-range options use independent weekly cohorts, which means late July and August weeks often have seats when earlier weeks are full.
MindCraft Makerspace Summer Camp at 2501 Dallas St runs $300-$500/week with 130 sessions. Northeast Denver location, hands-on making and engineering. This is one of the better-positioned last-minute STEM options because of the high session count and the location's relative scarcity of competing specialty programs.
CodeNinjas at 101 Ulster Ct runs $279/week for 120 sessions. The per-week pricing is flat and the cohorts are independent, which makes late registration straightforward. Good for kids ages 7-14.
Denver Museum of Nature and Science (DMNS) at 2001 Colorado Blvd runs $300-$410/week with 155 sessions. DMNS is normally the first program to fill in January, and the early weeks will be gone. But DMNS runs sessions deep into August, and cancellations from families who over-registered are common in May and June. Put your name on their waitlist immediately and call every two weeks.
Wings Museum has two locations: 7711 East Academy Blvd and 13005 Wings Way. Both run $399/week. Between the two locations, they have 170 total sessions. Aviation and aerospace focus, age ranges 5-14. The second location (Wings Way) tends to have more availability.
CES Mines at 924 16th Street runs $300-$500/week with 90 sessions. Colorado School of Mines affiliation gives it credibility with STEM-focused families, and the Golden-adjacent location is useful for west Denver and Jefferson County families.
Citation Capsule: Denver's mid-range STEM camp programs, priced between $279 and $500/week, include CodeNinjas at 101 Ulster Ct ($279/week, 120 sessions), MindCraft Makerspace at 2501 Dallas St ($300-$500/week, 130 sessions), and Wings Museum at two metro locations ($399/week, 170 combined sessions). These programs use independent weekly cohorts, meaning later summer weeks can have openings even when earlier sessions are full (ProjectKids, 2026).
What sports camps still have openings in Denver after May 1?
Sports camps fall into two categories for late registrants: large session-count programs that structurally retain availability, and specific-week openings within programs that are mostly full. The difference matters because your approach changes.
Denver Tennis Park at 1560 S Franklin St runs $200-$400/week with 150 sessions. Tennis instruction for ages 5-17. Washington Park location, good for South Denver and Capitol Hill families. High session count means late availability is common, especially for the older age brackets.
Avid4 Adventure Wash Park Rock Climbing at 1650 S Birch St runs $740/week with 70 sessions. This is the most expensive outdoor program on the list, but rock climbing is scarce at this age level. Call Avid4 directly. Their Wash Park location tends to have June availability even when the Boulder-area locations are full.
adidas Tennis Youth Camp at Metropolitan State University at 890 Auraria Pkwy runs $385-$435/week with 90 full sessions. Campus setting, structured instruction, all 90 sessions listed as full in our data. But "full" in May sometimes means "one waitlist spot behind a family that will cancel in June."
COED Ninja Summer Camp at 4860 Van Gordon St runs $335/week with 60 sessions. Ninja obstacle course and gymnastics-style programming. Lakewood-area location, ages 5-12. The ninja format is popular with kids who resist traditional team sports.
Venture Martial Arts at 8270 E Northfield Blvd runs $399/week with 60 sessions. Northeast Denver location. Martial arts camps are worth checking late because they often fill slower than team sports, and the skills transfer to confidence and focus in ways parents appreciate by fall.
Summer Camp at 1886 South Pearl St runs $200-$400/week with 90 sessions. South Pearl Street location in Platt Park, general athletics focus. Worth calling.
Are there outdoor and nature camps still accepting registrations?
Outdoor programs are a mixed picture in May. The established multi-week programs like Avid4's general outdoor sessions tend to close early. But single-facility programs that run weekly cohorts often have late availability.
Denver Zoo at 2300 Steele St runs camps at $85/week with 70 sessions. That price point is exceptional for a named venue with real educational programming. Denver Zoo camps are age-segmented (typically 4-12), and the youngest age groups often have the most cancellations. The Zoo is worth calling even if their website shows limited availability.
Hrcaonline at 9568 S. University Blvd runs outdoor and nature camps at $250-$450/week with 140 sessions. Highlands Ranch community association, south suburban location. The session count is high enough that late availability is likely.
Survive the Wild at 11280 Waterton Rd runs $350/week with 50 sessions. Wilderness survival skills in a real outdoor setting. Not a program you'll find easily with a Google search, which is exactly why it might have late spots.
Butterflies at 6252 W 104th Ave runs $325/week with 60 sessions. Westminster location, nature-based focus for younger kids. The northwest suburban families who commute to Boulder or the Tech Center are the target audience.
Botanic Gardens runs programs at $350/week at two locations: 1007 York Street (68 sessions, listed full) and 8500 W Deer Creek Canyon Rd (48 sessions). Both locations run waitlists and see cancellations. York Street is the better-known location; the Deer Creek Canyon site has more availability.

What's the actual strategy for registering last-minute in Denver?
Here's what the spreadsheet approach actually looks like. Start with the programs that have the most total sessions. A program with 730 sessions (Colorado Academy Summer) is structurally different from a program with 40 sessions. The high-session programs are essentially running continuous enrollment because their capacity is large and their cohorts overlap. The 40-session boutique programs have no structural late availability, only cancellations.
Your prioritized call list, in order: Colorado Academy Summer (3800 S Pierce St, 730 sessions), TPRD (16799 E. Lake Ave, 410 sessions), School of Rock Denver (560 S Holly St, 100 sessions), MindCraft Makerspace (2501 Dallas St, 130 sessions), Denver Tennis Park (1560 S Franklin St, 150 sessions). Call each one on a Tuesday or Wednesday morning. Mondays are chaos. Friday afternoons get voicemail.
For waitlist strategy: DMNS, Denver Zoo, and Botanic Gardens (York St) are worth waitlisting even if they show as full. These programs see structured cancellation waves in late April, mid-May, and the first week of June as families finalize vacation plans. If you get on the waitlist before those waves, you'll likely get a call.
Denver Summer Camp Registration Dates 2026
Citation Capsule: Programs with the highest session counts in Denver retain structural late availability because their enrollment capacity exceeds typical demand curves. Colorado Academy Summer (730 sessions at $150-$350/week), TPRD (410 sessions at $200-$400/week), and School of Rock Denver (100 sessions at $250-$450/week) are the best targets for May and June registration attempts (ProjectKids, 2026).
Frequently asked questions
Is it really too late to find Denver summer camps in May?
Not entirely. About 40% of Denver's 232 tracked programs retain open sessions into late May, primarily in the rec center, arts, and STEM categories (ProjectKids, 2026). The premium programs (DMNS, iD Tech, Denver Zoo) will be mostly full, but waitlists are real. Mid-tier programs with high session counts, like Colorado Academy Summer and MindCraft Makerspace, often have direct openings.
What Denver camps are cheapest for last-minute registration?
Camp Apex at 13150 W. 72nd Ave is $65-$85/week and uses flexible enrollment. Denver Zoo at 2300 Steele St is $85/week. Denver Parks and Recreation programs run $150-$350/week across 37 locations. Summer Dance Camps at 3001 Industrial Ln runs $60/week. These four represent the best budget options for families registering after May 1.
Should I call camps or register online for last-minute spots?
Call. Camp offices are small operations and their online systems frequently lag behind actual availability by 24-48 hours. A phone call to a camp registrar on a Tuesday morning can surface a spot that won't appear online until Thursday. Explain your situation directly. Ask whether they have cancellation openings or a same-week standby list.
What if my kid needs full-day coverage, not just a specialty week?
TPRD at 16799 E. Lake Ave, Colorado Academy Summer at 3800 S Pierce St, and Denver Parks and Recreation rec center camps all run full-day schedules with the structural capacity to handle late registrations. For working parents who need 8am-5pm coverage, these three should be your first calls. YMCA of Metropolitan Denver locations also run full-day camps and typically hold availability into May with extended care options.
What about waitlists? Do they actually move?
Yes, and more than most parents expect. Denver camp waitlists move in predictable waves: late April (families finalize vacations), mid-May (school calendars clarify), and the first week of June (final schedule conflicts surface). Get on waitlists now even if you're three or four spots back. Call the camp every two weeks. Don't email. The parent who calls is the one who gets the call back.
