Yogi Bear is spoiled for choices when it comes to snatching picnic baskets; Yellowstone has 52 designated picnic sites scattered throughout the park. Each site has picnic tables and most have vault toilets, while camping stoves and self-contained charcoal grills may be used in designated areas, while campfires may be lit only in locations with fire grates. The Madison site is the only location with potable water; visitors are encourages to pack in and pack out their water at all other locations. A picnic under the vertical rock columns of Sheepeater Cliff (south of Mammoth) is a unique experience, and may yield yellow-bellied marmot sightings. Yellowstone River Picnic Area is a great place to begin a wildlife excursion.
