The Detroit Zoo is an above average zoo that is trying hard to become even better. In the last few years they've created a new ape exhibit (Chimps and Gorillas in their natural habitat) and Amphibiville (Frogs, lizards, etc.). The new Arctic Ring of Life exhibit will open in October 2001.
The facility is clean and well maintained. There is a train that goes from the front to back in case you're tired of walking.
The zoo is owned by the City of Detroit, but actually located in the City of Royal Oak. You can enter the parking lot off of the WB I-696 service drive or SB Woodward Avenue (M-1). Just watch the signs, you can't miss it.
