Denver’s thriving food and drink scene include an annual restaurant festival in February and March. The city also has a rich history in brewing, and downtown you’ll find many brewpubs and microbreweries – plus, every autumn the city hosts the Great American Beer Festival and the Denver Beer Fest. Colorado’s natural wonders are easily accessible from the city, and you can also discover the region’s fascinating frontier past by taking a journey on the Georgetown Loop Railroad, with its panoramic views across forests and valleys.

Don't Forget Before you Fly

To enter the United States using a British passport you’ll need prior authorisation, either through a visa, a Permanent Resident Card, or the Visa Waiver Programme. You may find it useful to have some US dollars with you when you arrive, especially if you plan to take public transport from the airport into the city. Don’t forget to check that your travel insurance includes cover in the US.
