ACTIVITIES: Fishermen pursue Yellowstone cutthroat trout and rainbow trout throughout the park. Grebe Lake, known for arctic grayling, requires a 3.2-mile hike. Almost 1,000 miles of hiking paths lace through the park. Guided wildlife hikes are available through the nonprofit Yellowstone Association Institute (www.yellowstoneassociation.org).
