Best Summer Camps in San Mateo 2026: The Mid-Peninsula Parent's Guide

San Mateo is the quiet center of gravity for Peninsula summer camps. Sitting midway between San Francisco and Palo Alto with easy access to 101 and 280, it draws programming from every direction — national brands like Camp Galileo and Steve & Kate's, a strong City Parks & Recreation system, the Peninsula Family YMCA, the Boys & Girls Clubs of the Peninsula, and a growing cluster of STEM and arts specialists. For families in Foster City, Belmont, Burlingame, and Hillsborough, San Mateo is the natural hub.

The result is one of the densest camp markets on the Peninsula — and one of the least written about. Most parents default to searching city-by-city or scrolling ActivityHero without realizing how much is available within a 10-minute drive of downtown San Mateo.

This guide organizes the top summer camps in and around San Mateo by category, with real pricing, age ranges, and 2026 registration details. Whether you need full-day coverage for working parents, a budget-friendly anchor, or a specialty STEM week, it's here.

City of San Mateo Parks & Recreation — The Local Anchor

The City of San Mateo Parks & Recreation department runs one of the Peninsula's most diverse municipal camp systems. Programs span traditional day camps, specialty arts, musical theater, sports, science, chess, filmmaking, coding, and a full aquatics schedule.

Core camp programs include:
- Pre-Kamp — Half-day program for younger campers
- Camp Mateo — Traditional full-day camp with rotating weekly themes
- X-treme Summer Days — Action-packed weeks with field trips, activities, and transportation included
- Leaders in Training — For older campers ready to build leadership skills

Registration opens March 18, 2026 at 9:00am for San Mateo residents and March 20 at 9:00am for non-residents. Register online at sanmateorec.org.

Financial assistance: The Recreation Fee Assistance Program offers 30% or 60% fee waivers for qualifying San Mateo residents based on reported income. This is a real program — if cost is a concern, apply before registration opens so you're ready.

Late pickup policy: $1 per minute after the first five minutes — worth knowing if your commute is unpredictable.

City Rec camps are the natural anchor for a San Mateo summer. Many families book two to four weeks here, then fill specialty weeks with Galileo, YMCA, or STEM programs.

Peninsula Family YMCA — Best Full-Day Option for Working Parents

Ages: TK–8th grade (age 4–13) | Hours: 8am–5:30pm (M–F) | Location: 1877 South Grant St, San Mateo, CA 94402

The Peninsula Family YMCA runs one of the most comprehensive summer camp programs in San Mateo County. With hours stretching from 8am to 5:30pm Monday through Friday, it's built for working parents who need reliable coverage — not just a few hours of supervised play.

2026 Camp Programs:

Dates: June 15 – August 7, 2026 (no camp June 19 for Juneteenth or July 3 for Independence Day)

Financial assistance is available through the YMCA of Greater San Francisco. Applications are accepted in English, Spanish, and Chinese, with processing taking approximately 15 business days. Third-party billing (Children's Council, 4Cs) is also accepted.

Contact the camp director, Christina Johnston, at [email protected] or (650) 294-2608. Register at ymcasf.org/summer-camp-peninsula.

The YMCA is the right call for families who need 8am–5:30pm coverage and want a structured program with real variety — not just babysitting with a camp label.

Camp Galileo San Mateo — Best STEAM Day Camp

Ages: K–10th grade | Hours: 9am–3pm + extended care | Location: Meadow Heights Elementary, 2619 Dolores St, San Mateo, CA 94403

Camp Galileo is the gold standard for STEAM day camps in the Bay Area, and San Mateo families have a location right in the city at Meadow Heights Elementary. Galileo's curriculum blends hands-on innovation projects — wearable tech, engineering challenges, stop-motion animation, rocketry — with collaborative outdoor play and creative exploration.

2026 Pricing by Grade:

Note: Nebulas pricing includes $20/week for a higher staff-to-camper ratio. Meteors Go-Kart weeks include a $100 materials fee.

Steve & Kate's Camp San Mateo — Best for Schedule Flexibility

Ages: 4–12 | Hours: 8am–6pm | Location: St. Gregory School, 2701 Hacienda St, San Mateo, CA 94403

Steve & Kate's is built around one idea: working parents need flexibility. There are no fixed weekly sessions. You buy day passes and use them across the full summer however your schedule requires. Kids choose their own activities each day from rotating stations — stop-motion animation, sewing, coding, VR experiences, robotics, baking, tinker/maker lab, sports, and water play.

2026 Pricing:

All rates include lunch, snacks, and full-day hours (8am–6pm). Unused passes receive an automatic refund by September 11, 2026.

Dates: June 11 – August 7, 2026 (closed July 3)

At the Summer Pass rate, that's approximately $83/day for the full summer — a competitive rate when you factor in included meals and 10-hour coverage. For families with unpredictable schedules, the no-waste refund policy makes Steve & Kate's one of the lowest-risk commitments on the Peninsula.

Camp Integem — Best for AI, AR, and Cutting-Edge Tech

Ages: 6–18 | Location: Hillsdale High School, 3115 Del Monte St, San Mateo, CA 94403

Camp Integem is one of the most distinctive STEM camps on the Peninsula. It runs courses covering AI, Augmented Reality (AR) coding, robotics, 3D design, drone technology, game development, and animation — real emerging tech, not just basic coding tutorials.

Students are grouped by age: 6–8, 8–10, 10–14, and 14+. The older teen program covers college-level coursework in Interactive AR Animation. Younger groups have their own age-appropriate curriculum.

Dates: June 15 – July 24, 2026 (Monday–Friday)

Use code FUN26 at checkout for enrollment savings. Register at camp.integem.com.

Contact: (408) 459-0657

Integem is the right call for kids who are genuinely excited about AI and want to build real projects — not just follow along in a workbook. For a full regional overview, see Top STEM Summer Camps in the Bay Area 2026.

Boys & Girls Clubs of the Peninsula — Best Affordable Full-Day Program

Ages: 6–18 | Area: Daly City to East Palo Alto (multiple San Mateo County locations)

The Boys & Girls Clubs of the Peninsula (BGCP) is the largest out-of-school-time youth developer in San Mateo County, serving communities across the entire Peninsula corridor. BGCP runs structured summer programs combining academics, recreation, sports, and enrichment at multiple locations throughout the county.

BGCP programs are among the most affordable structured options available. Early registration discounts are offered, and the organization serves a broad socioeconomic range — making it a genuine option for budget-conscious families, not just a last resort.

Registration for 2026 summer programs is open at bgcp.org.

CodeREV Kids San Mateo — Best for Coding and Game Design

Ages: 6–15 | Location: San Mateo

CodeREV Kids runs STEAM-focused camps with courses in coding, game design, robotics, engineering, and animation. Programs are led by experienced instructors and organized by age and skill level — so kids who've never coded sit in different groups than those building their third game.

CodeREV's strength is depth: they don't try to cover everything. Kids pick a track (Minecraft modding, Python game design, robotics engineering, app development) and go deep for the week. That focus produces real skills, not just a participation certificate.

Registration Tips: What San Mateo Parents Need to Know in 2026

1. City Rec registration opens March 18 — set a reminder. San Mateo residents register at 9am on March 18; non-residents on March 20. Popular programs (aquatics, musical theater, X-treme Summer Days) fill within days. Register at sanmateorec.org.

2. Apply for financial aid before registration opens. If your family qualifies for the City's 30–60% fee waiver, the YMCA's financial assistance, or BGCP's programs, submit applications now so you're ready when registration opens. Don't wait until spots fill.

3. Galileo runs through July 24, not August. Camp Galileo's San Mateo session ends July 24 — earlier than most camps. Plan your August weeks with YMCA, Steve & Kate's, or City Rec to avoid gaps.

4. Steve & Kate's starts earliest (June 11) and runs latest (August 7). If you need coverage before other camps begin or after they end, Steve & Kate's flexible day-pass model fills those gaps without committing to a full week.

5. Mix categories for the best summer. A typical San Mateo approach: 2–3 weeks of City Rec (affordable anchor), 1–2 weeks of Galileo or Integem (specialty STEM), 1 week YMCA (full-day adventure), and Steve & Kate's day passes to fill gaps. Total summer cost can range from under $500 to over $4,000 depending on the mix.

6. Extended care matters. Confirm extended care availability before you register. YMCA covers 8am–5:30pm standard. Steve & Kate's runs 8am–6pm included. Galileo charges $36–$90/week for extended care. City Rec varies by program.
