You’ll have to pick your jaw up off the ground before you start your alfresco breakfast or dinner on Elk Island, in the middle of Jackson Lake in Grand Teton National Park. Just one mile from Elk Island (the largest island in Wyoming—not a hotly contested title), the hulking Mount Moran explodes up 7,000 feet from the lakeshore. It’s so close you might be able to spot crevasses on one of its glaciers. In this setting, standard fare—trout, steak, and chicken at dinner, and eggs, pancakes, and hash browns at breakfast—tastes almost sublime. The cruise to and from the island is a bonus.
