Animal lovers young and old can get a rare close look at beautiful and rare wolves at the Endangered Wolf Center (formerly known as the Wild Candid Center). Home to endangered wolves from around the world, the center is located in Eureka, Mo., about a 40-minute drive from downtown St. Louis. Visitors choose from two kinds of tours: a two-hour tour, which includes an educational presentation about wolves in addition to a walk through the wolf pens; or a one-hour tour, which is basically a guided walk through the wolf enclosures.
