A playground with a bathroom

A playground without a bathroom is a different outing. These are the parks where both are confirmed present.

Confirmed true on both counts, not assumed. Plenty of parks have restrooms nobody has checked — they are missing from this list rather than guessed onto it.

Bellevue
State park · Wilmington
Brandywine Springs Park
New Castle County · Wilmington
Portable toilets on site, not permanent restrooms. Seen in person; whether they stay through winter I did not check.
Can-Do Playground
Delaware State Parks · Wilmington
Between the Can-Do Playground and the Ninja Fit course, and well kept. Confirmed in person.
Carousel Park
New Castle County · Wilmington
Confirmed present. Type and season still unchecked.
Delcastle Recreational Park
New Castle County · Wilmington
Listed by New Castle County, and new bathrooms at the softball quad were completed by December 2025. Whether any of them are open year round is not published.
Glasgow Regional Park
New Castle County · Newark
Confirmed present. Whether they are a permanent block or portables, and whether they are open year-round, is still unchecked.
Iron Hill Park
New Castle County · Newark
On the county's facility feature list. Read there, not visited — type and season still unknown.
Talley Day Park
New Castle County · Wilmington
Confirmed present. Still to check: whether these are the park’s own facilities or the adjacent library’s — it matters, because the library keeps shorter hours than the park.
Wilmington State Parks
State park · Wilmington
