While not technically in Boise, Bogus Basin is so close it may as well be! They are a non-profit dedicated to accessible, affordable and fun year-round mountain recreation and education. It’s a fancy way of saying there’s always something to do in the foothills of Boise.
In the winter, they have skiing, snowboarding, sledding, snowshoeing, and even some concerts.
They’re open in the summer too! They have hiking, mountain biking, their “Gladerunner”, summer tubing, and even a climbing wall.
