How many days in Denver? 4 days, the Mile High City and the Rockies
By Tony Panopoulos · travel-agency planner in Greece · Updated
Denver sits on the plains exactly one mile (1,609 metres) above sea level, with the Front Range of the Rockies filling the western horizon. The city itself takes two days: a compact downtown around Union Station, a strong museum district and the murals and breweries of RiNo. The other two days belong to the mountains, which start 25 minutes away. Give it four days, drink more water than you think, and book the Rocky Mountain National Park timed-entry permit before you arrive if you travel between late May and October.
Short answer
Two days covers downtown, the museums, RiNo and an evening at Red Rocks. Four days adds Boulder and a full day in Rocky Mountain National Park, the main reason many people fly into Denver.
The 4-day plan, day by day
Day 1: Union Station, LoDo and the Capitol
Morning. Start at Union Station, the restored 1914 terminal whose Great Hall is now a lounge with cafés and the Crawford Hotel. Walk through LoDo (Lower Downtown), the old warehouse district, past Coors Field and along Larimer Square, Denver's oldest block, strung with lights.
Afternoon. Walk the 16th Street pedestrian mall (about 20 minutes) to the gold-domed Colorado State Capitol; free tours run on weekdays, and the 13th step outside is marked at exactly one mile high. Across Civic Center Park, the Denver Art Museum (about US$25-30 for non-residents) has a strong collection of Indigenous art in the Martin Building.
Evening. Eat downtown or in Union Station, then catch a Rockies baseball game at Coors Field in summer (tickets from about US$15-30), or see the Clyfford Still Museum next to the art museum, open late on some evenings.
The altitude hits harder than visitors expect: drink water, go easy on alcohol on the first night, and wear sunscreen even when it is cool.
Day 2: RiNo, the Botanic Gardens and Red Rocks
Morning. Walk 15-20 minutes north from Union Station to the River North Art District (RiNo), whose warehouse walls are covered in murals, many painted for the annual Crush festival. Have brunch at Denver Central Market on Larimer Street.
Afternoon. Take a ride-share east to the Denver Botanic Gardens at York Street (about US$15-20), with alpine plants from the Rockies and a Japanese garden, or the History Colorado Center downtown for the state's mining and ski history.
Evening. Drive 25-30 minutes west to Red Rocks Amphitheatre, a 9,500-seat concert venue between two 90-metre sandstone monoliths. Concerts run from about April to October; on non-show days the park and its trails are free to visit until sunset.
Red Rocks shows sell out early; if you cannot get in, go at sunset on a free day and walk the 2 km Trading Post Trail.
Day 3: Boulder and the Flatirons
Morning. Drive or take the RTD Flatiron Flyer bus (about 45-50 minutes) to Boulder. Walk up from Chautauqua Park below the Flatirons, tilted slabs of rock on the foothills; the Royal Arch trail is about 5 km return with a steep climb, the Chautauqua trail meadow loop much easier.
Afternoon. Walk the Pearl Street Mall, four pedestrian blocks of shops and street performers, and the University of Colorado campus. Tea lovers can visit the Celestial Seasonings tea factory.
Evening. On the way back, stop in Golden (about 30 minutes from Boulder), a small 1859 gold-rush town, for the Coors Brewery tour and a drink by Clear Creek. Return to Denver for dinner.
Afternoon thunderstorms are common in summer in the foothills; start hikes early and be off exposed ridges by about 13:00.
Day 4: Rocky Mountain National Park
Morning. Leave by 6:30 to drive 1.5-2 hours to Estes Park and the park entrance (about US$30 per vehicle for a day; from 2026 non-US visitors pay a higher annual pass price and a surcharge at the busiest parks, so check nps.gov). Walk the easy loop around Bear Lake, then continue to Nymph, Dream and Emerald Lakes, about 5 km return.
Afternoon. Drive Trail Ridge Road, the highest continuous paved road in the US, reaching about 3,713 metres (open roughly late May to mid-October, depending on snow). Stop at the Alpine Visitor Center and look for elk and marmots on the tundra.
Evening. Have dinner in Estes Park before driving back to Denver, or stay a night there to drive Trail Ridge again at dawn.
Between late May and October, timed-entry reservations on recreation.gov are needed for most hours of the day, and the Bear Lake Road corridor needs its own permit. They are released monthly and a day ahead.
Only have 2 days?
With 2 days, do Day 1 and combine RiNo with an evening at Red Rocks on Day 2. You lose Boulder and the national park.
Got extra days?
Extra days can go to the summit road of Mount Blue Sky (formerly Mount Evans, about 4,300 metres, reservation required, summer only), to the ski towns of Breckenridge and Vail (about 1.5-2 hours), or south to Colorado Springs for the Garden of the Gods and Pikes Peak (about 1 hour 15 minutes).
Where to stay in Denver
| Budget | Area | Why | Typical double/night |
|---|---|---|---|
| Budget | Capitol Hill / airport-line hotels | Older hotels and hostels near Colfax Avenue, a short walk to downtown. | US$110-170 |

Getting around
Downtown is walkable, and the free MallRide shuttle runs along 16th Street. RTD light rail and buses cover the city; the A Line commuter train links Denver International Airport with Union Station in about 37 minutes (about US$10). For Red Rocks, Golden and the national park you need a car: rentals cost about US$50-90 a day. Ride-shares cost about US$10-20 within the city and US$60-80 from the airport.
What to eat in Denver
Denver's dish is green chile, a pork-and-chile stew poured over burritos and breakfasts; try it at a classic diner. The Denver omelette comes with ham, peppers and onion, and Rocky Mountain oysters (fried bull testicles) are a dare at old steakhouses. Bison burgers and steaks appear on many menus. The city is one of America's great craft beer towns, with over 100 breweries; a pint costs about US$7-9. Food halls such as Denver Central Market, Avanti in the Highlands and Zeppelin Station in RiNo have dishes for US$13-20. Tip 18-20% at sit-down restaurants.
Best time to visit
June to September for the mountains, with Denver highs of 27-32°C and cooler air in the park; September has golden aspen in the high country and fewer crowds. Winter brings sunny days around 7°C in the city, often with snow that melts quickly, and ski season in the mountains from about November to April. Spring is changeable, with snowstorms as late as May.

Before you go
Common questions
Do I need a car in Denver?
Not for the city: the A Line from the airport, light rail, the 16th Street shuttle and ride-shares cover downtown, RiNo and the museums. For Red Rocks, Golden, Boulder's trailheads and Rocky Mountain National Park, a car is far easier. Many visitors rent for just the mountain days, picking up in the city rather than at the airport to save fees.
Will the altitude affect me?
Some people feel mild symptoms at 1,609 metres, such as headaches, poor sleep and shortness of breath on stairs. They are stronger in the national park, where trails start at 2,500-3,000 metres. Drink plenty of water, limit alcohol for the first day or two, and turn back on any hike if you feel dizzy or nauseous.
How do the Rocky Mountain National Park permits work?
From late May to mid-October, you need a timed-entry reservation from recreation.gov for most of the daytime, plus the park entrance fee. One permit covers most of the park; another, with a separate time window, covers the Bear Lake Road. Permits are released at the start of the previous month, with a smaller batch the evening before.
Can I see a concert at Red Rocks?
Yes, from about April to October, and it is one of the most famous venues in the US. Tickets sell out quickly for big names, so book as soon as they go on sale. Shuttle buses run from downtown for many shows. Even without a ticket, you can visit the amphitheatre and its trails for free on non-show days.
