Both the Zoo and School are located on the same site, just north of Spokane, Washington.  Exit off Interstate 90 on Division Street (Hwy 395 & Hwy 2); travel north (approximately 12 miles) at which time Hwy 2 (Newport Hwy) separates and requires you to turn off to the right.  Follow Hwy 2 for 6 miles and the zoo will be on your right.  The exit is Carney Road.
