Spotting grizzlies and gray wolves in Yellowstone National Park can be a challenge. The creatures are most active in the evening and early morning, when sightseers are usually at dinner or in bed.

With eight grizzly bears and a pack of gray wolves, the facility offers a chance to view the impressive animals in a nearly natural setting and to learn about ongoing efforts to safeguard both species within the park. The center is open year-round. (800) 257-2570, www.grizzlydiscoveryctr.org.
