Where to rent a car in Denver

You can rent a car in Denver from three types of locations: major chains at Denver International Airport (DEN), downtown locations in the city, and off-airport independent agencies. Airport rentals are the most convenient if you're arriving by plane, but they charge facility fees that can add 15 to 25 percent to your daily rate. Downtown Denver locations on 16th Street and near Union Station have lower base rates but require you to arrange your own transportation to pick up the car.

The major chains operating at DEN include Enterprise, Hertz, Budget, Avis, and National. Each has a separate counter in the rental car facility on the lower level. If you're renting downtown, you'll find Enterprise, Hertz, and Budget locations within walking distance of the 16th Street Mall. Independent agencies like Fox Rent A Car and Thrifty operate both at the airport and in the city, often with lower daily rates but fewer vehicle options.

Off-airport agencies in neighborhoods like LoDo (Lower Downtown) and near I-25 typically quote $5 to $15 less per day than airport counters, but you'll need a ride to get there. If you're staying at a hotel, ask whether they offer a shuttle to a nearby rental location—many do.

Key Takeaways

  • Airport rentals at DEN are fastest but include facility fees; downtown locations cost less per day but require separate transportation to pick up the car.
  • You'll need a valid driver's license, a credit card in your name, and proof of insurance (your own policy or the rental company's coverage) before you can drive off the lot.
  • Daily rates in Denver range from $30 to $80 for economy cars depending on season and how far in advance you book, with summer and ski season commanding higher prices.
  • Declining the rental company's insurance costs you nothing upfront but leaves you personally liable for damage; check whether your credit card or personal auto policy covers rentals first.
  • Booking directly on a rental company's website usually costs less than booking through a third-party site, and you can often modify or cancel without penalty up to 24 hours before pickup.

What documents and information you need to bring

Bring your valid driver's license (U.S., Canadian, or International Driving Permit), a credit card in your own name, and proof of insurance. The credit card must have enough available credit to cover the estimated rental cost plus a hold for damage—typically $200 to $500 depending on the vehicle class. Some companies accept debit cards, but they require a larger hold and may refuse you if your account balance is low.

For insurance, you have three options: use your own auto policy if it covers rentals (call your insurer before you book), purchase the rental company's Collision Damage Waiver (CDW) or Loss Damage Waiver (LDW), or rely on your credit card's rental car coverage. Read your credit card's terms carefully—many exclude luxury vehicles and require you to decline the rental company's insurance to set up the card's coverage. If you have no insurance at all, the rental company's CDW typically costs $15 to $25 per day and is worth buying.

Bring a second form of ID if you have one (passport, military ID, or state ID card). Some companies ask for it; most don't, but it speeds up the process. If you're under 25, expect to pay a young driver surcharge of $15 to $30 per day—this is standard across the industry and non-negotiable.

How to book and compare prices

Book directly on the rental company's website rather than through Kayak, Expedia, or Autoslash if the price is the same or lower. Direct booking lets you modify your reservation, add or remove insurance, and cancel up to 24 hours before pickup without penalty. Third-party sites sometimes lock you into non-refundable rates or make changes difficult.

Compare prices across at least three companies before you decide. Enter your pickup date, time, and location, then note the daily rate, facility fees (at the airport), and any mandatory charges. A $40-per-day quote at the airport becomes $50 to $55 after fees; the same car downtown might be $35 all-in. Use Google Flights' car rental tool or visit each company's site directly—both show the full price before you commit.

Book at least one week in advance if possible. Rates are lowest when you book 7 to 14 days ahead; booking the day before pickup costs 30 to 50 percent more. If you're traveling during ski season (December through March) or summer (June through August), book three weeks out. Weekday pickups are usually cheaper than Friday or Saturday.

Understanding daily rates and hidden fees

A quoted daily rate is not your final cost. At Denver International Airport, the facility fee adds roughly $5 to $7 per day on top of the base rate. The state of Colorado charges a 4 percent rental tax on top of that. If you decline the rental company's insurance and buy your own, that's separate. If you add a second driver, some companies charge $10 to $15 per day; others don't charge at all.

Fuel is your choice: return the car with a full tank (you pay for gas at market rates), or let the rental company fill it and charge you their rate (usually 30 to 50 percent above pump prices). Always choose to return it full yourself unless you're extremely short on time. GPS rental costs $10 to $15 per day; use your phone's maps instead. Child car seats cost $10 to $15 per day if you need one.

Late return fees start at $40 to $50 if you bring the car back after your agreed time. Damage charges depend on what you hit—a small dent might be $500 to $1,000 out of pocket if you declined insurance. Toll charges on I-25 or the E-470 toll road are billed to your credit card weeks later if you don't pay at the booth; the rental company adds a processing fee on top.

What to check before you drive away

Before you leave the lot, walk around the car with the rental agent and photograph or video any existing damage—dents, scratches, stains, or broken trim. Point out each one and ask the agent to note it on the contract. Take photos with your phone; most agents will wait while you do this. This protects you from being charged for damage you didn't cause.

Check that the fuel gauge reads full (or whatever level was promised), the lights work, the wipers function, and the tires look intact. Test the air conditioning and heat. Locate the spare tire and jack. Ask where the fuel door release is if you can't find it. If anything is broken or missing, tell the agent when ready and have them document it.

Confirm your return date, time, and location before you drive away. If you're returning to a different location than you picked up from, verify that the one-way fee (if any) is already in your quote. Ask whether the location is open 24 hours or has limited hours—returning a car after hours may trigger late fees even if you're technically on time.

Driving in Denver and returning the car

Denver's main roads are I-25 (north-south), I-70 (east-west), and I-225 (southeast loop). Downtown is compact and walkable; parking is available but costs $2 to $5 per hour in lots and on the street. The E-470 toll road circles the metro area and charges $2 to $5 per trip depending on time of day—you'll be billed automatically if you don't have a toll pass. Speed limits are 25 mph in downtown, 35 to 45 mph on city streets, and 65 to 75 mph on highways.

Return the car with a full tank of fuel, clean of trash and personal items, and with no new damage. Most rental locations accept returns 24 hours a day—you can drop the key in a slot after hours. If you return during business hours, an agent will inspect the car and compare it to the photos taken at pickup. If you return after hours, the company will inspect it the next morning and email you a receipt within a few days.

Keep your rental agreement and receipt. If you're charged for damage you didn't cause, you'll need them to dispute the charge with your credit card company or insurance provider. Most credit card companies will reverse rental damage charges if you provide evidence (photos, the agent's notes, or a police report if applicable).

Frequently Asked Questions

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

Yes, but you'll pay a young driver surcharge of $15 to $30 per day. You must be at least 18 and have a valid driver's license. Some luxury or specialty vehicles have a minimum age of 25 regardless of surcharge.

What happens if I return the car late?

Late fees typically start at $40 to $50 for the first hour, then $10 to $15 per additional hour or day. If you're running late, call the rental location and ask whether they can extend your reservation—sometimes they can waive the fee if the car isn't already booked for another customer.

Do I have to buy the rental company's insurance?

No. If your personal auto policy or credit card covers rental cars, you can decline the rental company's coverage. Read your policy or credit card terms before you book to confirm what's covered. If you have no coverage, buying the rental company's Collision Damage Waiver is worth the $15 to $25 per day.

Is it cheaper to book at the airport or downtown?

Downtown is usually cheaper per day, but airport is faster if you're arriving by plane. A downtown car might be $35 per day all-in, while the same car at the airport is $40 to $50 after facility fees. If you're staying near downtown Denver, the savings add up over a week-long rental.

What if I get a flat tire or the car breaks down?

Call the rental company's roadside information number—it's on your rental agreement. They'll send a tow truck or replace the tire at no cost to you. Don't attempt repairs yourself or take the car to an independent mechanic; the rental company will cover the cost through their roadside service.
