Loveland Living Planet Aquarium
The default bad-weather answer for the south valley. Busiest on weekend afternoons and during school holidays; mornings are much calmer.
Places that are always there
Not events. These are open most of the time, which makes them the answer when the calendar is thin or the weather turns. Seasonal places are hidden automatically when they are shut.
Draper
Midvale
Nickel Mania
Cheap enough that a small budget lasts, which is the whole appeal.
Riverton
Salt Lake County Library, Riverton
Free, warm, and open when almost nothing else is. Runs its own children's programmes, which the library events source picks up separately.
Salt Lake City
Clark Planetarium
The exhibit floor costs nothing, which makes it a genuine free option rather than a ticketed one with a free corner.
West Jordan
Gene Fullmer Recreation Center
Indoor pool, so it answers the winter version of the same question.
