What It Is
Mini Monster's Bash is a ticketed Halloween event at The Children's Museum at La Habra on Saturday, October 24, 2026, from 5 to 8 p.m. The format is a trick-or-treat trail through the museum galleries with crafts, games, and a live Mad Science show at 6 p.m.
Why Go
The museum format gives you a scaled-for-younger-attendees Halloween event with the Mad Science demo as the anchor, inside a controlled indoor environment. Capacity is capped and admission is separate from regular museum entry, which keeps the pacing manageable.
What To Know Before You Go
Location: The Children's Museum at La Habra, 301 S Euclid St, La Habra. Date: Saturday, October 24, 2026. Hours: 5 to 8 p.m. (Mad Science show at 6 p.m.). Price: $20 per person age 2 and up (general); $15 museum members; $10 Access Pass members; under 2 free. Tickets: preregistration required, every guest 2 and up (adults included) needs a ticket, limited capacity, nonrefundable, not included with regular museum admission. Parking: free, at the Portola Park lot south of the museum. Pro tip: buy tickets ahead; the capacity cap is real and sold-out status is not posted in advance.
The Honest Take
Separate ticketing from regular museum admission means a family of four pays $80 for the general tier (or $40 for members), which is a real number for a three-hour event. The anchor is the Mad Science show plus the trick-or-treat trail; if those two are the draw for your group, the ticket math holds. If you were hoping to add it onto a regular museum day, note that this ticket does not include the galleries outside of the Bash footprint.
