Coastside History Museum
Best for ages 3–8+; younger kids welcome
Free
Saturdays and Sundays, 10:30am–4:30pm; extra days/times when docents are available
505 Johnston Street, Half Moon Bay, CA 94019
What it offers
Small-but-rich local history museum behind the historic 1919 jail, with artifacts and exhibits about Ohlone history, farming, railroads, surfing, and Coastside cultures
Why parents might like it
Better as a 20–45 minute “let’s pop in” stop than a big museum day. Good for a Main Street wander: look at the artifacts, peek at the native plant garden, and let kids ask the docents questions.
Before you go
The museum remains open weekends while the historic jail is closed for restoration until October 2026. Weekday openings depend on docent availability. Pair with lunch, coffee, or errands downtown.
Amenities
ADA accessible; indoor exhibits; native plant garden; knowledgeable docents; downtown nearby
