Boise Open Streets
Hosted by the Boise Bicycle Project, Open Streets Boise temporarily transforms neighborhood streets into car-free community spaces where folks can bike, walk, and roll together. Open Streets Boise moves between neighborhoods highlighting different neighborhoods and local businesses. Explore local food, art, family-friendly entertainment, and live music in a welcoming atmosphere where we can come together and reimagine our streets as a place for people, not just cars. In 2026, Open Streets Boise is made possible with support from the City of Boise and in partnership with the Collister Neighborhood Association.

Boise Citywide Tree Planting
Join Trees Idaho and City of Boise for our annual neighborhood tree planting!
Throughout the city, volunteers and staff will be planting trees at homes and parks provided by the Elaine Clegg City of Trees Challenge.
During the event, we’ll be helping residents plant trees at their homes and neighborhoods—providing guidance, tools, and hands-on support to make sure each planting is successful. This is a great opportunity to meet neighbors, learn about tree care, and make a lasting impact on our urban forest. No experience needed and all ages are welcome (we even have kid-sized shovels and gloves!)
Join us to help grow a greener, healthier, and more resilient City of Trees!

Dandelion Fest is Saturday, June 20th! Join a guided bike tour led by Trees Idaho through Boise’s East End to visit champion trees: the biggest, oldest, and most remarkable trees in the East End. At each stop, a Trees Idaho guide shares the tree’s story: what species it is, how old it is, what it does for the neighborhood, and why it matters.
Awe at the scale and age of trees they’ve been walking past. A new way of seeing their own neighborhood. The feeling of standing in the shade of something that’s been quietly caring for this place longer than anyone alive.
