Renting a car in Denver is essential for exploring Colorado — there’s little transit outside the city, and none reaching the scenic mountains. DiscoverCars lists Denver rentals from around $37/day (and $32/day at the airport), so comparing suppliers is the easiest way to find a good rate. Here’s how Denver car rental works, from the airport to Rocky Mountain National Park.
Key Takeaways
- Denver rentals start around $37/day, or $32/day at Denver Airport (DEN).
- A car is essential — there’s no public transit to Rocky Mountain National Park.
- Rocky Mountain NP is just 75 miles (about 90 minutes) from Denver.
- In winter, choose 4WD or AWD for the mountains and snow.
- There are no gas stations inside Rocky Mountain NP — fill up beforehand.
Do You Need a Car in Denver?
Yes — especially for the mountains. There’s little transportation in Colorado outside Denver, and no public transit connecting the city with Rocky Mountain National Park or the scenic high country. A rental is the only practical way to reach the state’s best landscapes.
Downtown Denver is walkable, but the moment you want to explore beyond it, a car becomes essential. That’s exactly why Denver is such a popular rental base for a Colorado road trip.
Is Denver a Good Base for Rocky Mountain National Park?
It’s ideal. Rocky Mountain National Park sits just 75 miles (about 90 minutes) northwest of Denver, making it one of the best day trips from the city. The road network inside the park is in good shape, and you can explore most of it by car.
Even if you’re not hiking, the drive is worth it — Trail Ridge Road climbs to breathtaking alpine scenery. Note the $35 vehicle entrance fee, and remember there are no gas stations inside the park, so fill up before you go.
Where Do You Pick Up Your Car at Denver Airport?
Denver International (DEN) is the busiest airport in the state and has the largest rental selection, with rates from around $32/day. Free shuttles from Jeppesen Terminal (level 5) run directly to the Car Rental Center, so pickup is straightforward.
Picking up and dropping off at the airport usually saves money compared with neighborhood locations, thanks to that bigger fleet and competition. Follow the signs to the rental shuttle after baggage claim.

What Kind of Car Should You Rent in Denver?
It depends on the season. In summer, a standard sedan or SUV handles the paved mountain roads fine. In winter, choose a 4WD or AWD vehicle if you’re heading into the mountains, where snow and ice are common — it makes a real safety difference.
For Rocky Mountain day trips or family adventures, an SUV adds comfort and cargo space. For getting around downtown, a compact is cheaper and easier to park. Match the car to your plans and the time of year.
Is DiscoverCars Good for Denver?
Yes — DiscoverCars compares Denver suppliers in one search with the full price shown upfront, including the low airport rates from around $32/day. Because Colorado is a competitive market, comparison helps you find the best deal and the right vehicle for the season.
Most bookings include free cancellation up to 48 hours before pickup. Compare Denver rental prices on DiscoverCars to find the best rate for your Rocky Mountain road trip.
Bottom line: a rental car is essential for exploring Colorado beyond Denver — there’s no transit to the mountains. Rent at Denver Airport for the best rates and selection, choose AWD in winter, fill up before Rocky Mountain NP, and compare on DiscoverCars.
What Other Trips Can You Do From Denver?
Denver opens up far more than Rocky Mountain National Park. Scenic mountain towns like Boulder, Estes Park, and the ski resorts are all within a short drive, and the dramatic peaks along I-70 make even the highway a highlight. A rental makes every one of these reachable.

When Is the Best Time to Visit Rocky Mountain National Park?
Summer is peak season, when Trail Ridge Road is fully open and all the trails are accessible — but it’s also busiest, so start early to beat traffic. Fall brings golden aspens and thinner crowds, while winter limits high-elevation roads and demands AWD.
Whatever the season, book your rental early and match the vehicle to the weather. A summer sedan is fine, but a winter mountain trip calls for 4WD or AWD.
