Transport to Boulder from DEN: Options include SkyRide bus (RTD route AB/FF1, around $10), shared shuttles or rideshare (around $60).
Note: Boulder is more than 20 miles (32 km) from DEN, so airport surcharges shouldn't apply even if you flew in the same day (unlike locations closer to Denver International Airport).

Saving Tips
- Shop multiple pick-up spots: Compare Boulder in-town branches with nearby Longmont/Broomfield and even DEN airport. A cheaper day rate at the airport can get wiped out once you add the $10 SkyRide bus or $60 rideshare, so run the numbers first.
- Peak dates = book, then stalk prices: CU graduation, summer weekends and ski season push rates up fast. Reserve a cancelable deal a few weeks out, then keep checking—if prices dip you can re-book in two clicks.
- Match your hours to the depot: Most Boulder counters close around 5:30 pm and many snooze on Sundays. Schedule pickup/drop-off inside those windows so you don't pay an extra "ghost" day or after-hours fee.
- Leverage Boulder's free parking windows: City garages are free all weekend and the first 90 minutes on weekdays. If your hotel charges for parking, leave the car in a garage and pocket the savings.
- Skip the US-36 express toll lane: The regular lanes are right next to it and cost $0. Dodging the toll also avoids the rental company's admin fee that appears on your card a month later.

FAQs
Do I need a car in Boulder if I'm staying downtown?
If you plan to stay in downtown Boulder, University Hill and areas the city bus goes to, you might not need a car. You can easily walk around Boulder and the public transportation is good. However, you'll find a car useful for getting to hiking trails, mountain areas and nearby towns.
What type of vehicle is best for exploring around Boulder?
We recommend an AWD/4WD vehicle that has good clearance for year-round driving, especially if you plan to go into the mountains. This is more important in the winter so you can safely drive in the snow. If you're only driving in the city during summer, any type of car will work fine.
Where is the best place to park for Pearl Street Mall?
You can find convenient parking in the city garages at 10th & Walnut, 11th & Spruce or 15th & Pearl. They are free on weekends and holidays and you get the first 90 minutes free on weekdays. You can also find street parking, but it's usually limited to 2 hours.
Are there any parking restrictions during snow events?
Yes, when it snows heavily, Boulder sets up snow emergency routes where you can't park while crews clear the snow. You should check the street signs and the city website during snowstorms. The areas around the university have extra parking rules during snowstorms too.
How do I handle toll roads with a rental car?
US-36 between Boulder and Denver has express toll lanes. If you use these lanes, your rental company will charge the tolls and a service fee to your credit card. The regular lanes are still free. To avoid any charges, just stay out of the lanes that have toll signs.
Is it difficult to find parking near hiking trailheads?
Parking at popular trailheads like Chautauqua Park fills up very early (before 7am) on summer weekends. You can use the Park-to-Park shuttle service during the busy season or try visiting on a weekday. You'll usually have an easier time finding parking at less-known trailheads.
Can I take my rental car on unpaved mountain roads?
Most rental car companies don't allow you to drive their cars off-road. However, you can usually drive on well-kept dirt roads that lead to trailheads. You should check your rental agreement and stay off rough 4x4 trails. If you cause damage on those trails, your rental coverage may not apply.
Is it worth renting from DEN airport versus in Boulder?
If you are arriving at DEN, you'll find a better selection of cars and more flexible hours if you rent there, but you will have to drive to Boulder. If you're already in Boulder and need a car, renting locally means you won't have to go back to the airport. You should compare the total costs, including transportation, to decide what's best for you.
