Updated August 24, 2026
This week: Aug 27 – Sep 3 · Next week: Sep 3–10
This week's weather · It's a dry week ahead, so these indoor picks are great for whenever you need a break from the heat — or just a change of scenery.
When the rain rolls in and the kids are bouncing off the walls, Diablo Valley has you covered. Local libraries and community spots around Contra Costa County pack their calendars with free and low-cost indoor fun all week long.
This week
This week is packed with great indoor options for kids across the valley. On Tuesday, the Kiddo Crafternoons at Concord Library and the Children's Jazz Program at Walnut Creek Library are both wonderful ways to spend a rainy afternoon — and if your reader wants a furry audience, Read to a Dog at Lafayette Library is always a hit. Wednesday brings the Insect Discovery Lab as part of Wonderful Wednesdays: Insect Discovery Lab at Clayton Library, and Thursday has Crafternoons with I Heart Art at Walnut Creek Library plus the Pop-Up Crafternoon at San Ramon Library. Train fans won't want to miss the Walnut Creek Model Railroad Society Train Show on Friday night, and Saturday the Lego Builders Club at Pleasant Hill Library is a perfect rainy-day closer.

Tips
- 💡
Are library programs really free?
Most are — just show up. A few may ask you to register online first, so check the library's website or call ahead to confirm.
- 💡
What ages do these programs work for?
It varies by event. Read-to-a-dog and craft programs often welcome ages 5+, while music and LEGO programs can skew a bit older. Check each listing.
- 💡
Do I need a library card to attend?
Usually not for drop-in programs — anyone can walk in. A card is handy if you want to check out books while you're there, though!
- 💡
What if my kid has a short attention span?
Drop-in formats like crafternoons and tech help are low-pressure — come and go as you like. No need to stay the whole time.
