Here are more freebies around town you can mark your calendar for. 

The Denver Children’s Museum is free on the first Tuesday of each month from 4-8 p.m. It’s called Target Tuesday nights because the event is sponsored by Target.

The Denver Zoo will allow Colorado residents to visit free on Oct. 13, Oct. 21, Nov. 7 and Nov. 13. 

The Rocky Mountain Arsenal used to make nerve gas and napalm. Now it’s a National Wildlife Refuge. It’s open to the public Tuesday, Wednesday, Saturday and Sunday from 7 a.m. to-5 p.m. Call 303-289-0930. There are tram rides and wildlife programs, all for free.

You can smell the peppermint and learn about tea on the free tour at Celestial Seasonings in Boulder. Children must be 5 and older to go on the tour. There are even free tea samples in the tasting room. 

While you’re in Boulder, consider a stop at the Leanin’ Tree Museum and Sculpture Garden of Western Art. Admission and parking is free. Some call it the best small museum in the state. 

Need something fun to do with the kids? How about storytime? Several local libraries and even the Tattered Cover bookstore host storytimes for kids. And they’re free. 

You can also see the exhibits (and run the stairs) for free at Red Rocks. And while you’re in Morrison, don’t miss the dinosaur footprints on Dinosaur Ridge. It’s free too. 

Sandie, one of our readers, suggested another good free place to visit is the Littleton Historical Museum. Sandie said it’s one of her family’s favorites.
