Travel can increase your chances of getting and spreading COVID-19. We ask all visitors to respect the wishes, public health guidelines, and capacity of our local destinations. Keep in mind that guidance may vary county by county, so it’s important to plan ahead, be prepared, and be flexible. Colorado’s Dial Dashboard provides information regarding current county-level guidelines and restrictions.

Things to consider

  • Fully vaccinated travelers are less likely to get and spread COVID-19. Someone is fully vaccinated when it has been at least two weeks since they received their last recommended dose of a COVID-19 vaccine. 

    • Fully vaccinated travelers do not need to get tested before or after travel within the United States unless their destination requires it. 

    • International travel poses additional risk so all travelers should get tested 3-5 days after traveling internationally.

    • Fully vaccinated travelers do not need to self-quarantine.

    • Fully vaccinated travelers should still follow CDC’s recommendations for traveling safely, including wearing a mask, keeping 6 feet of distance from others, and washing hands frequently.

  • Non-essential travel is not recommended for people who have not been fully vaccinated.

  • Find out if COVID-19 is spreading where you’re going and always check restrictions in the area to which you are traveling. View Colorado’s Dial Dashboard or contact the area’s local public health agency to get the most up-to-date information on local orders and variances.

  • If you or those you are traveling with are at higher risk for serious illness from COVID-19, consider limiting your travel.

  • Traveling to places where there is widespread transmission or to places where you intend to participate in large gatherings increases your chances of being exposed to COVID-19. 

  • For any trip, consider what you will do if you become ill while you’re away. You may need to isolate or quarantine away from home if you develop symptoms or are exposed to the virus while traveling.

When to avoid travel

  • If you are sick.

  • If you have been around someone with COVID-19 in the past 14 days.

  • If one of your travel companions is sick.

People who are sick, have recently tested positive for COVID-19, or have been exposed to a person with COVID-19 pose a risk to others and should not travel.

If you become sick or are exposed to COVID-19 while traveling in Colorado
  • If you become sick or are exposed to COVID-19 while traveling in Colorado

  • In Colorado, the local or state public health agency may issue public health orders to quarantine or isolate if you test positive for COVID-19, become ill, or are exposed to someone with COVID-19 while you are visiting. 

  • Public health orders may limit your travel or even require you to stay in Colorado during your quarantine or isolation, at your own expense. This means you may not be able to leave the state, regardless of how you travel (e.g. private car or airplane). This ensures not only your safety but the safety of those you may come in contact with on your trip home.

Travelers should stay informed and take preventive actions

  • Protect yourself and others during your travels:

    • Make or buy a mask that fits well and covers your mouth and nose completely. Wash reusable cloth masks frequently.

    • Avoid close contact with others. Keep six feet of physical distance from others, even when wearing a mask.

    • Avoid crowded areas and settings.

    • Frequently and thoroughly wash your hands with soap and water for at least 20 seconds. If soap and water are not available, use hand sanitizer with at least 60% alcohol.

    • Cover coughs and sneezes with a tissue, then throw the tissue in the trash, or use your inner elbow or sleeve.

    • Avoid touching your eyes, nose, and mouth.

    • Stay home if you’re sick, and keep your children home if they are sick.
