This is the country's first cageless zoo. There are no bars separating you from your view of the lions, giraffes and great apes. In summer, the animals are not as active -- head over to the Penguin House or the Arctic Ring of Life to see penguins and bears keeping their cool. In the Arctic Ring of Life, you can walk through a tube that allows the animals to swim directly over your head. The curator is credited for removing the elephants to a warmer climate -- so you can rest assured that this is ONE zoo in America that puts the welfare and comfort of its animals first -- before gate revenue. Perhaps it has fewer animals than other zoos (unless you count all the amphibians, reptiles and prairie dogs), but still an enjoyable afternoon. There's a train that generations of Detroiters have ridden, recently upgraded and refurbished to its past glory. It will take you from the front of the park to the back, or from the back to the front. Its extra fee is worth budgeting for, the park is quite large and the little ones (either your kids or your feet) will get tired from the walking. Winter in the park is wonderful -- bundle up and go from building to building and take in the sights along the way. If you get really cold, head over to the butterfly house or the aviary. There are picnic areas and a playscape, if the weather is nice, too. Haven't ridden the new antique carousel, but its beautiful. My favorite place for photos is in front of the amazing fountain at the center of the park.
