Hey there, families, and welcome to Erika’s Picks. For years, I’ve been looking for the best family-friendly events happening each weekend around the greater Seattle area. Whether you’re looking to explore a new park, attend a fun workshop, or catch a local performance, I’ve got you covered. Each week, I’ll share my handpicked activities that will keep the little ones entertained, engaged, and maybe even learning something new. So, grab your calendar, gather up your crew, and get ready for a fun-filled weekend! Let’s dive into Seattle family events for the weekend of Sept 5-7, 2026.

The Ellensburg Rodeo has earned its place as one of America’s Top 10 professional rodeos and it’s just 2 hours from Seattle! Started in 1923, the rodeo has grown from a local competition among ranch hands to an event with over 600 contestants. Head out I-90 this weekend and watch riders, ropers, and wrestlers compete, and then head into the Kittitas County Fair to see 4H animals up close, ride the carnival rides, explore the art barns, and eat all the best fair food. It’s a great weekend for all ages! The rodeo runs three hours each day, but the fair stays open until late into the night. FYI – Monday fair admission is free for everyone!
