Cheap flights from San Diego to Denver

When traveling from the Pacific Coast to the Rocky Mountains, renting a car when you arrive at Denver International Airport (DEN), from San Diego International Airport (SAN) is an easy choice, that allows you to control your schedule. After enjoying miles of beautiful driving and bird-watching with the Audubon Society, you can still make that Broncos' game at Mile High Stadium in your rental vehicle.

Key Facts

If you are spending time in Denver, having a car at your disposal allows you to easily make the 90-minute drive from the city on US-36 W or I-25 N, to visit the Rocky Mountain National Park. You may want to consider renting an SUV with bike racks, so that you can enjoy the beauty of more than 850 miles of mountain biking adventures, awaiting you. The park was established in 1915, and it is open all year round, offering a wide variety of exciting activities for every season. You can view the natural wildlife, take a sled trip, or go cross country skiing during the winter months.

Hints and Tips

A flight from San Diego to Denver normally takes about two hours. However, be aware that because you will change from being in the Pacific Time Zone, to the Mountain Time Zone, it will be one hour later in Denver when you arrive.

*Price based on the lowest price found within past 24 hours and based upon one night stay for two adults over the next thirty days. Prices and availability subject to change. Additional terms may apply.
