Imagine sitting down to pan–seared Copper River salmon with toasted couscous and lemon–chive butter—in Alaska’s Denali National Park. More and more park restaurants are serving natural meats, responsibly harvested seafood, and local produce.

At Colorado’s Mesa Verde, executive chef Todd Halnier of the Metate Room serves grass–fed lamb from a local ranch and gets "sweet, amazing" corn from the local Ute tribe.

You’ll also find burgers made with natural or grass–fed beef. "It’s the right choice to make," says Tim Stein, food and beverage director with Xanterra, a principal park concessionaire. Here are some notable dishes.
