A valley surrounded by glorious snow-capped mountains. It's in southwestern Idaho and is super hot in the summer and can be downright cold in the winter. There's no in-between. Cities that make it up are Boise, Meridian, Nampa, Caldwell and many other small rural towns. Ski resorts are nearby and great forests and rivers. Its volcanic soils make it great farming for alfalfa, corn, sugar beets, beets, beans, onions, mint, mustardseed, and yes, potatoes. And it has orchards and great wineries also! Over 600,000 people call this place home and some can't wait to get out but still love it. And teenagers are at Dutch Bros. all the time(it's pretty good). Overall, it's a beautiful metropolis with that small-town, friendly feel.
Person 1: This place is amazing.

Person 2: It's like I'm in the Treasure Valley again!

Get the treasure valley mug.
A tattoo placed on the small of the back, most often on females. Associated with the location of Boise, in the treasure valley.
All of the tattoos I did today were treasure valley targets.
