Speaking as a dad/husband in a family of five, doing anything as a family is crazy expensive these days, so anytime I can find a deal like the one happening this weekend, I jump on it!

The Denver Museum of Nature & Science and the Mexican Cultural Center are celebrating Día del Niño (the Day of the Child) this Sunday (Apr. 28) with free admission to the museum. 

In addition to free general admission for all visitors, the celebration will include special performances, music, and activities for the entire family.

Guests can also enjoy 50% off admission to the temporary exhibition “Orcas: Our Shared Future” and 50% off admission to Infinity Theater and Gates Planetarium showings throughout the day.

The museum says that there is no need to reserve a ticket ahead of time online. Walk up anytime between 9 a.m. and 5 p.m. to gain access to the Wildlife Halls or the permanent exhibitions.

If you can’t make it for this free day, the museum will also offer free admission on June 4* and 19, Aug. 21*, Sept. 10* and 30, Nov. 2* and 18, and Dec. 8. *Free only from 5 to 10 p.m.
