Parque Infantil del Niño José “Remi” Vega

If you’ve got kids under 8 and you’re spending the day in Old San Juan, this spot is worth knowing about. The Dr. Seuss theming is done really well — bright, bold colors that actually hold up in person and characters the little ones recognize immediately. There’s musical equipment the toddlers go absolutely feral for, shaded seating so you’re not melting while you watch them, and restrooms close by which, honestly, makes or breaks a park visit. Snack vendors are usually around, so you can grab something without having to pack up and leave. It fits right into the neighborhood — urban, lively, but with enough shade and charm to make it a genuine stop rather than just a quick detour.
