What to do on a no-school day in New Castle County
Teacher in-service days, district holidays, the odd random day off — they land mid-week when you weren't planning for them, and the weather's a coin flip. These are our go-to spots for filling a whole no-school day in New Castle County: places that work rain or shine, hold a kid's attention for a few hours, and don't require booking a camp. A couple are worth-the-drive for a bigger day out.
1. Delaware Children's Museum
Wilmington
The default no-school-day move for younger kids — hands-on exhibits that burn a solid two to three hours regardless of weather. Go right at opening to beat the field-trip crowds that sometimes share weekday mornings.
2. Delaware Museum of Nature & Science
Wilmington
Dinosaurs, a reef, and a regularly-changing feature exhibit make this an easy all-ages indoor day. Pairs well with a stop nearby if you've still got energy left.
3. Fred Rust Ice Arena (UD)
Newark
Public skating sessions are an underrated day-off plan when you want the kids genuinely worn out — indoor, year-round, and not weather-dependent. Check the public-session schedule, which shifts around hockey and lessons.
4. Natural Nest Play Cafe
Newark
For toddlers and preschoolers, an indoor play café lets them loose while you actually sit down with a coffee. The low-stress option for a cold or rainy day off with little ones.
5. Please Touch Museum
Philadelphia
If you're making a real day of it, Philadelphia's children's museum is about 40 minutes up and easily fills a morning-to-afternoon. A strong worth-the-drive for a no-school day with younger kids.
6. Adventure Aquarium
Camden
Just over the bridge in Camden, the aquarium is a full indoor day for animal-obsessed kids — sharks, a hippo, and touch tanks. Buy timed tickets ahead to skip the line.

Questions parents ask
Where can I take my kids on a teacher in-service day near Wilmington?
For an all-weather day, the Delaware Children's Museum (younger kids), the Delaware Museum of Nature and Science, and public skating at the Fred Rust Ice Arena are reliable. For a bigger day out, Please Touch Museum in Philadelphia and Adventure Aquarium in Camden are both worth the drive.
What's a cheap or free thing to do on a day off school?
Pair an outdoor park trip with a packed lunch, or use a Delaware library card to reserve a free Museum Pass to a state park or the Brandywine Zoo. Our free things to do and free museum days guides have the full no-cost playbook.
Are there single-day camps on no-school days?
Often, yes — area museums, the Y, and some venues run single-day or in-service-day camps when school is closed but parents work. Availability changes by date, so check the specific venue's site for that day's offerings.
