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.

Logs, boulders, earth mounds and a willow hut make up most of this playground, with a fenced area for climbing, swinging and sliding.

Bowling alley off Union Square with bumpers and light lane food.

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, with eighteen holes that suit a school-age kid.

Food-truck yard with open turf for younger kids to run about while you eat, and a mini golf course for older ones.
