Cheap flights from St Louis to Denver

Whether you're traveling from St. Louis, to Denver International Airport (DEN) for business or pleasure, you'll find plenty to enjoy in the Queen City of the West. As the capital of Colorado, Denver stands at exactly 5,280 feet above sea level, hidden away in the midst of the snow-capped Rockies. In this outdoor lover's paradise, you can hike Green Mountain, kayak in Confluence Park, go whitewater rafting in Idaho Springs, or see a show at the Red Rocks Amphitheater.

Key Facts

Having a rental car during your vacation, is helpful for taking day trips up the Mount Evans Scenic Byway, the highest paved road in America. Many downtown attractions however, are reachable by using the city's eco-friendly "Green Fleet" public transit system. Park for free on the outskirts of town, and catch a ride on the metro, to visit the Denver Art Museum, take the kids to the Denver Zoo, tour the U.S. Mint, or grab some locally made beer at the Coors Brewery.

Hints and Tips

After traveling about one hour and forty minutes from Lambert-St. Louis International Airport (STL), you'll touch down in in the world's fifth busiest airport. Since DEN welcomes more than 52 million passengers yearly, it's best to hop on the Peak 1 Express Mountain Shuttle, to navigate the crowds to your car rental. Once you're behind the wheel, take Peña Blvd. to Interstate 70 and begin exploring Denver.
