How old do you have to be to rent a car in Boulder County?
Rental vehicle rules in Boulder County require drivers to be 21 and above. Are you a younger driver? Some restrictions and surcharges may apply. Rental providers impose what is known as a young renter surcharge, which is an extra fee to the cost of the rental car. Restrictions often apply to the sorts of cars available to young motorists as well. Age limits may differ between outlets, so check before you book.
What do you need to rent a car in Boulder County?
Renting a car in Boulder County is easy as pie. Normally, all that's required is a valid driver's licence and a credit card in the same name. After settling on your wheels, read your policy to ensure there are no extra requirements prior to pickup.

Head to our long-term car rental deals page, enter your trip details and then lock in your ideal ride. Whether you're stopping in Boulder County or exploring beyond, Expedia will help you find a long-term rental at an amazing rate.
Where can I find a Boulder County car rental if I am younger than 25?
You'll need to investigate the age policy of the Boulder County rental suppliers you're considering. If you're under 25 years of age, some companies will charge additional costs. It's ideal to know this before collecting the vehicle so you can have the funds ready. Each rental car company has its own rules for young drivers, so do your research.
