Luma Hotel San Francisco

A waterfront playground that works well as a quick stop on a stroller walk, with paths and open space continuing along the creek.

A playground handy to have in mind when you're near a Warriors game or nearby performance.

Bowling alley off Union Square with bumpers and light lane food. Daytime is the family window.

Mission Bay food-truck park with lawn games and room for strollers; every age finds something.

Outdoor mini golf at Mission Rock built around the city's gold-rush history. Eighteen holes holds a school-age kid; a toddler will want to leave at nine.

Mission Bay food-truck yard with open turf, so younger kids can run about while you eat.
