Where to rent a car in Denver and what to expect

Denver has rental desks at Denver International Airport (DEN), downtown locations on 16th Street, and neighborhood branches in Cherry Creek and South Denver. The airport location is the most convenient if you're arriving by plane, but you'll pay an airport concession fee on top of the daily rate — typically 10 to 15 percent higher than off-airport locations. If you're renting from downtown or a neighborhood branch, you avoid that surcharge but need your own transportation to reach the counter.

The major chains operating in Denver are Enterprise, Hertz, Budget, Avis, and National. Each has different daily rates, mileage policies, and insurance options. Smaller agencies like Fox Rent A Car and Thrifty also operate in the area and sometimes undercut the majors on price, though they may have older vehicles or stricter cancellation policies. Rates vary by season — summer (June through August) is peak pricing, while winter and early spring are cheaper.

You'll need a valid driver's license, a credit card in your name, and proof of insurance before you can pick up a car. Some agencies require you to be at least 25 years old; those that rent to drivers 21 and up charge a young driver fee of $15 to $30 per day. Have your license and credit card ready when you arrive — the process usually takes 15 to 30 minutes at the counter.

Key Takeaways

  • Airport rentals cost 10 to 15 percent more than off-airport locations because of concession fees, so compare prices at downtown branches if you have ground transportation.
  • Daily rates in Denver range from roughly $35 to $80 for economy cars depending on season and agency, with summer rates significantly higher than winter.
  • Your personal auto insurance or credit card may cover rental car damage, so check your policy before paying for the rental agency's collision coverage.
  • Fuel charges vary widely — some agencies charge $6 to $8 per gallon if you return the car empty, so fill up at a regular gas station before returning.
  • Reservation cancellations are usually free up to 24 hours before pickup, but some budget agencies charge a fee, so read the terms when you book.

Daily rates and what affects the price you pay

A basic economy car in Denver rents for $35 to $50 per day in winter and $55 to $80 per day in summer. Midsize sedans run $45 to $60 in winter and $70 to $95 in summer. SUVs and trucks cost more — $60 to $80 in winter and $90 to $130 in summer. These are ballpark figures; actual prices depend on the specific agency, how far ahead you book, and whether you're renting on a weekend (usually more expensive) or weekday.

Booking directly through an agency's website is often cheaper than booking through a travel site like Kayak or Expedia, because those sites add their own markup. However, travel sites sometimes have exclusive discounts or package deals if you're bundling the rental with a hotel. Compare the final price (including all fees) on both before you commit. Some agencies offer loyalty discounts if you're a member of their rewards program, which can save 10 to 20 percent.

The airport concession fee is not optional — it's built into every airport rental. Off-airport locations in downtown Denver or neighborhoods like South Denver avoid this fee entirely. If you're staying downtown or have a friend who can drop you off, an off-airport rental can save $50 to $100 over a week-long rental.

Insurance, damage coverage, and what your own policy covers

Rental agencies offer collision damage waiver (CDW) or loss damage waiver (LDW) coverage, which costs $12 to $25 per day. This covers damage to the rental car if you're in an accident. However, your personal auto insurance policy likely covers rental cars already — check your policy documents or call your insurer before you rent. If your policy covers rentals, you don't need to buy the agency's coverage and can save $84 to $175 over a week.

Credit cards also offer rental car coverage, but only if you use that card to pay for the entire rental. American Express, Visa Signature, and Mastercard Black typically include this benefit. Read your card's terms to see whether it covers collision, theft, and liability, or only collision. Some cards exclude certain vehicle types (like luxury cars or trucks), so verify your specific card covers what you're renting.

Liability coverage (damage you cause to other vehicles or property) is required by Colorado law and is included in every rental. You cannot decline it. If you cause an accident, the rental agency's liability coverage pays for the other party's vehicle and medical bills up to the policy limit, usually $100,000 to $300,000. Your personal auto insurance also covers liability on a rental, so you have two layers of protection.

Fuel charges and how to avoid paying premium prices

Most agencies offer a "full-to-full" fuel option: you pick up the car with a full tank and return it full. If you return it empty or partially full, the agency charges you for the fuel at a premium rate — typically $6 to $8 per gallon, compared to $3 to $4 at a regular gas station. Over a week-long rental, returning an empty tank can cost $40 to $60 more than filling up yourself.

Some agencies offer a "prepaid fuel" option where you pay for a full tank upfront at a slightly lower rate (around $5 per gallon). This makes sense only if you know you'll use nearly a full tank. If you return the car with fuel remaining, you don't get a refund — you lose the money. For most renters, the full-to-full option is cheapest: fill up at a Conoco, Safeway, or Kroger gas station near the rental return location about 10 minutes before you drop off the car.

Avoid the "fuel on return" option entirely — it's the most expensive choice. The agency charges you per gallon for fuel they pump into the car after you return it, and that rate is always higher than what you'd pay at a pump.

Airport pickup versus downtown and neighborhood locations

Denver International Airport has rental desks in the terminal, and you can pick up a car within 30 minutes of landing. The downside is the airport concession fee, which adds roughly $10 to $15 per day to your rental cost. For a week-long rental, that's $70 to $105 extra. The airport location is worth it if you have no other way to get downtown or if you're only renting for one or two days.

Downtown Denver has rental locations on 16th Street and nearby, accessible by RTD light rail from the airport (about 40 minutes, $10.50 one-way) or a rideshare (about 30 minutes, $20 to $35). If you take RTD or a rideshare to a downtown location, you'll save the airport fee and often get a lower daily rate. The trade-off is time spent getting to the rental counter instead of picking up at the airport.

South Denver and Cherry Creek neighborhoods have rental branches that are cheaper than downtown and avoid the airport fee. These locations are useful if you're staying in that area or if a friend can drop you off. Check whether the agency you want has a branch near your hotel or destination before you book.

Reservation cancellations and what happens if your plans change

Most major agencies (Enterprise, Hertz, Avis, National, Budget) allow free cancellation up to 24 hours before your pickup time. If you cancel within 24 hours, you may lose the rate you booked, but you won't pay a cancellation fee. Some budget agencies like Fox Rent A Car charge a cancellation fee of $25 to $50 even if you cancel well in advance, so read the terms when you book.

If you need to extend your rental after you've picked up the car, call the agency as soon as possible. Extending by a day or two usually costs the daily rate for those days, but if the agency has high demand, the extension rate may be higher than your original rate. It's cheaper to extend before you return the car than to rent again the next day.

If you're unsure about your exact return date, book for the shorter period and extend if needed. Booking longer than you need and canceling the extra days often results in a lower refund than the rate you'd pay to extend, because cancellations sometimes trigger non-refundable fees.

Age restrictions, additional driver fees, and who can rent

Most agencies rent to drivers 25 and older at the standard rate. Drivers 21 to 24 pay an additional young driver fee of $15 to $30 per day — for a week, that's $105 to $210 extra. A few agencies (Enterprise and Budget) rent to drivers as young as 20, but the young driver fee is higher. Drivers under 20 cannot rent in Colorado.

If you want to add another driver to the rental, most agencies charge $10 to $15 per additional driver per day. Some agencies include one additional driver for free if that person is your spouse or domestic partner. Check the agency's policy when you book. The additional driver must have a valid license and be present at pickup to sign the rental agreement.

You must have a valid driver's license (U.S., Canadian, or international license with an English translation) and a credit card in your own name. Debit cards are not accepted for the security deposit, though some agencies will accept them as a secondary payment method. The security deposit is typically $200 to $500 and is released after you return the car and the agency inspects it for damage.

Frequently Asked Questions

Can I rent a car at Denver airport if I'm under 25?

Yes, but you'll pay a young driver fee of $15 to $30 per day on top of the daily rate. Enterprise and Budget rent to drivers as young as 20, while most other agencies require you to be 25. You cannot rent if you're under 20.

What happens if I return the car late?

Late fees vary by agency but typically run $25 to $50 for the first hour and $50 to $100 per day after that. If you're running late, call the rental location as soon as possible — some agencies will waive a short delay if you notify them. Always plan to return the car at least 30 minutes before your reservation end time to avoid unexpected fees.

Do I need to buy insurance if my credit card covers rental cars?

No, if your credit card covers collision and theft, you don't need the agency's coverage. However, verify your card's terms before you rent — some cards exclude certain vehicle types or have high deductibles. Your personal auto insurance also covers rentals, so check that first.

Is it cheaper to rent from downtown Denver or the airport?

Downtown and neighborhood locations are cheaper because they avoid the airport concession fee (10 to 15 percent of the daily rate). For a week-long rental, you'll save $70 to $105 by renting downtown. The trade-off is getting to the rental location, which takes 30 to 40 minutes by RTD or rideshare from the airport.

What's the best way to avoid fuel surcharges?

Fill up the car at a regular gas station (Conoco, Safeway, or Kroger) about 10 minutes before you return it. Agencies charge $6 to $8 per gallon for fuel, compared to $3 to $4 at a pump. Returning an empty tank can cost $40 to $60 more than filling up yourself over a week-long rental.
