Support us when you shop

Shop Online

Did you know that every time you shop on AmazonSmile, a percentage of your purchase can be donated back to MDIA? At no cost to you, the AmazonSmile Foundation will donate 0.5% of every eligible purchase to MDIA when you designate us as your charitable organization of choice.

To get started, visit and login with your regular Amazon account information, select MT. Diablo Interpretive Association as your charitable organization, then start shopping!

We’ll only receive donations from purchases made through directly, rather than through, so be sure to bookmark!

Thank you for your support of MDIA and Mount Diablo State Park!
