Idaho Center, Entertainment complex in Nampa, US

The Ford Idaho Center is a sports and entertainment complex of nearly 100 acres in Nampa, about 15 miles west of Boise. It comprises an indoor arena with 12,279 seats and 31,200 square feet of floor space, a 10,500-seat outdoor amphitheater with a 60-by-40-foot stage, the Ford Idaho Horse Park and the Ford Sports Center, plus 104 RV spots for equine events.

The complex opened in 1997 with the completion of the main arena, serving the region from its start. The outdoor amphitheater was added the following year, expanding what kinds of events could be held there.

The Snake River Stampede, held annually in the third week of June, moved indoors to the arena in 1997 after decades at an outdoor stadium near Lakeview Park. The arena also hosts the Idaho Horse Expo and Low Roller, along with reining, roping, barrel racing, and youth and collegiate equestrian competitions.

The complex spans nearly 100 acres about 15 miles west of Boise, with separate arena, amphitheater, horse park and sports center areas, so check which one hosts your event. It has 104 RV spots for equine events. The arena floor covers 31,200 square feet.

The Idaho Horsemen played at the Ford Idaho Center from 2019 to 2025, first in the American West Football Conference and from 2024 in the National Arena League. The arena also hosted the largest basketball crowd in its history in March 2004, when 10,153 spectators watched Boise State face UWM after a Metallica concert displaced the game from Taco Bell Arena.
