Ada County, Idaho
Ada County sits in the heart of Idaho’s Treasure Valley. Boise, the state capital, anchors the county and gives it a hip urban vibe. The Boise River cuts through town, lined with a popular greenbelt for biking and jogging.
Foothills rise up north of the city, crisscrossed with hiking trails. It’s a fast-growing area, attracting tech companies and Californians fleeing high costs. Locals complain about the growth but secretly love the new restaurants.
The suburbs sprawl out into former farmland. Meridian and Eagle are booming. Downtown Boise has a surprising food scene and decent nightlife. BSU’s blue football field is a point of pride. You can ski, mountain bike, and fly fish all on the same day here.

OUTLINE MAP
Ada County Blank Map
Ada County’s outline is kind of a wonky rectangle, with slight cuts. The southwest corner aligns with Snake River, bordering Owyhee County. It’s not perfectly straight so it’s more like someone sketched it quickly but kept it neat.
