Frequently asked questions

When is Kids Free San Diego 2026?

October 1–31, 2026 (the 15th annual). Most deals run every day of the month; whale watching runs through Nov 15, and LEGOLAND and SeaWorld tickets have their own purchase windows.

Do I need a paying adult?

Almost always. The usual pattern is a full-paying adult plus the kids, and each venue sets its own age limit. Discount passes such as CityPASS, Go San Diego and the Balboa Park Explorer Pass generally don't count as the paid adult ticket.

How do I get the museum coupons?

Enter an email and zip code at the San Diego Museum Council's kids-free page to get a coupon you can show on your phone. Kids 12 and under are free with a paid adult at participating museums; special exhibits may cost extra and some museums limit it to once a month per guest.

Are restaurants and hotels part of it?

Yes — sandiego.org says the program includes 100+ museums, attractions, tours, hotels and restaurants. We only list deals we could confirm for 2026 from an official page; check sandiego.org for the full hotel and restaurant list.
