What do you need to rent a car in Boulder?
Your driver’s license and a credit card in the same name are necessities. Don’t want to take out the company’s insurance plan? Then you may also need proof of your own coverage. Requirements may differ from rental company to rental company, so read through your policy.
Can I rent a car for a month or longer in Boulder?
Yes, so you won’t have to rebook a rental vehicle mid-vacation. Click through to our long-term car rental deals page, enter your trip details and reserve a ride that’s all yours for the duration of your escape.
Where can I find a Boulder car rental if I am younger than 25?
You’ll need to check the age policy of the Boulder rental providers you’re considering. If you’re under 25, be aware that some will charge additional fees. It’s good to know this before collecting the vehicle so you can budget accordingly. Each rental car company has its own policies for young drivers, so it’s smart to do your research.
