FAQs about travel to Denver

Helpful information for travellers to Denver, Colorado

How long are flights from Europe to Denver?

Icelandair offers several flights to Denver from Ireland and other European cities every single day. Where you are flying from will depend on how long the flight will be. For example, Dublin to Denver flights can take around 12 hours. Add layover time, and the trip to Colorado can take a little longer.

Which Denver airport should I fly to?

Denver has two main airports – Denver International (DEN) and Denver Arapahoe Co (APA). DEN is the main airport that services the city and the greater Front Range Urban Corridor. It's easy to get from here to downtown Denver on the airport rail line.

Several airlines fly to Denver Arapahoe Co Airport (APA), but Icelandair offers flights to Denver International Airport (DEN), making your trip to downtown Denver that bit easier.

Do you need a visa to visit Colorado?

If you’re travelling from Ireland, you’ll need a visa to get into the US. We recommend checking the US State Department website to see which type of visa you need and how to get it before booking a flight ticket to Colorado.

What’s the best way to get around Denver?

Thanks to its layout, Denver is a walkable city and is easy to get around. Many of its most popular things to do can be found within walking distance of one another in the downtown area.

There are taxis and uber services available throughout the city, and it has an excellent light rail and bus system if you would prefer to use public transport.

Best time to travel

The best time to fly to Denver is from June through October, when visitors can enjoy summer days on the hiking trails and longer days for driving through the mountain passes.

Although the summer months do get hot, you can always escape to the mountains to cool off.

If you want slightly cooler days, we recommend visiting in the shoulder seasons that run from April to May and September to October. This is the perfect time to avoid the crowds, find affordable accommodation, and book cheap flights to Colorado.

Whenever you decide to visit, flights to Denver from the UK and Ireland are made possible with Icelandair. You also have the option to add a stopover in Iceland at no additional airfare.

Things to do in Denver, Colorado

Outdoor activities in Colorado

From the airport, a 20-minute drive takes you to Colorado Springs, the foothills of the Rocky Mountains, for a variety of outdoor activities.

In summer, visitors can enjoy hiking, rafting, kayaking, fishing, and mountain climbing, plus excellent golf courses. Meanwhile, come winter, skiing and snowboarding is enjoyed by travellers and locals alike.

Colorado boasts some of the world’s finest ski resorts, and within a two-hour drive from Denver you'll find winter wonder at places like Keystone, Breckenridge, and Winter Park. Press a little further west and you'll reach the jewel in the crown: Vail. This is the state's largest resort, and one of its most celebrated.

There are countless other super-scenic natural attractions. To reach road-tripping nirvana in summer, drive North America’s highest paved road up to the 14,264ft summit of Mt Evans. To head onwards to Grand Junction, rejoin Route 70 and head west.

Eating and drinking in Denver

Just northwest of downtown is the historic neighbourhood known as LoDo (Lower Downtown). Many buildings here have been restored and the now-revitalized area is filled with fine restaurants, bars, boutiques, and galleries situated alongside a bumper crop of breweries and brewpubs.

LoDo's Union Station Building dates from 1914, and it's been restored to house several restaurants, bars and even a hotel. It's a great place to check out the works of some of the city's best chefs.

Chic Highlands is another area for dining and drinking fun. Stop by the Avanti food hall, a culinary collective that brings together seven different restaurant operators.

Alternatively, under blue skies it's hard to beat a picnic at either the view-enriched City Park or the majestic Botanic Gardens.
