Car Rental Planning Tips

Book Pickup at DIA or Local Office: Denver International Airport has the widest selection, but Westminster rental locations often offer lower rates. Compare both before booking.

Reserve Early for Peak Seasons: Summer and fall see high demand—especially for SUVs and 4WD vehicles. Book at least two weeks ahead to secure your preferred car class.

Choose the Right Vehicle for Mountain Driving: All-wheel drive or a vehicle with good ground clearance is recommended for mountain passes and unpaved scenic roads, even in summer.

Check for One-Way Fees: If you plan to end your trip in another city, ask about drop-off charges. Some agencies waive them for certain routes or during promotions.

Prepare for Weather Changes: Mountain conditions can shift rapidly. In winter, snow tires or chains may be required on I‑70. Carry an emergency kit year‑round.

Fuel Up Before Heading into the Mountains: Gas stations are scarce in remote areas like Trail Ridge Road. Fill your tank in Estes Park, Boulder, or Idaho Springs to avoid running low.
