Denver, known as the “Mile High City,” is Colorado’s capital and largest city. By recent estimates its city population is about 715,000 (2020 Census: 715,522), making it the 19th-largest city in the U.S. The Denver metropolitan area (including suburbs) now approaches 3 million. Denver’s demographics are diverse: roughly 55% of residents are non-Hispanic white, and about 28% are Hispanic or Latino. African Americans make up around 8–9%, and there are growing Asian and mixed-race communities. Median age is in the mid-30s, reflecting a mix of young professionals and families. The city is relatively affluent: median household income is about $91,700, above national average, though cost of living (especially housing) is high. Unemployment is typically low, and key industries include finance, energy, aerospace, telecommunications, biotech, and increasingly tech startups (Denver now hosts over 180 fintech companies). Tourism is also a pillar: as the gateway to the Rocky Mountains, Denver draws millions for skiing, hiking, and conferences.
Denver is located on the South Platte River at the eastern edge of the Rocky Mountains. Its name comes from James Denver, a territorial governor, and in 1858 it was founded as a gold-rush era settlement. Today Denver sits at an exact elevation of 5,280 feet (1,609 meters) above sea level – hence the “Mile High” nickname. The city’s core sprawls across the High Plains; to the west the land rises into foothills. From downtown one can see mountain peaks on clear days. This high-altitude plains setting yields Denver’s semi-arid climate: 300 days of sunshine per year make it famously bright and dry. Summers are warm, often hitting the 90s°F (low 30s°C) but with low humidity, so days are comfortable even if hot. Afternoon thunderstorms are common in July and August, often soaking the city briefly. Winters bring cold, snow, and inversions: daytime highs in the 40s°F (4–9°C) and nights below freezing are typical, but sunny skies mean winter cold is usually tolerable (snow falls but often melts quickly on roads). Spring and fall are transitional and pleasant. Overall, Denver’s climate is among the mildest of major Rocky Mountain cities: the air is dry (a welcome contrast to East Coast cities) and temperatures moderate for most seasons.

With 715,000 residents (2020) in the city proper, Denver is a bustling urban center. The metro population is nearly 3 million across Denver and adjacent counties. Denver’s population has grown rapidly for decades, almost doubling since 1990. The city’s median household income is about $91,700, and about 11% of residents live below the poverty line (somewhat lower than national rates). The median age is relatively young, around 35.2 years, driven by new graduates and professionals moving to the city.
Demographically, Denver is 55% White (non-Hispanic) and 28% Hispanic or Latino (of any race). About 8.5% of residents are Black, 3.5% Asian, with smaller percentages of Native Americans and Pacific Islanders. The foreign-born population is around 13.7%, reflecting immigration from Latin America, Asia, and elsewhere. This diversity is evident in Denver’s neighborhoods: for example, the West Side has a strong Mexican-American heritage, Aurora (east metro) is highly diverse, and there are many international grocery stores and churches of varied backgrounds throughout the city.
Economically, Denver is one of the Mountain States’ powerhouses. Major industries include aerospace (several companies and federal agencies operate here, and the city’s 1950s tradition of aviation remains strong), energy and natural resources (Colorado is rich in oil, gas, and minerals, and Denver is a hub for petroleum and emerging green energy firms), financial services, telecommunications, healthcare, and education (the University of Colorado Denver and several college campuses are here). Over 180 financial technology firms (“fintech”) have set up shop in Denver. Denver also serves as government seat (the State Capitol is downtown) and a distribution/logistics center for the entire mountain region. When combined with tourism (Rocky Mountain recreation, conferences, sports events), the city’s gross metropolitan product ranks high nationally. Denver’s economy is thus multifaceted – a textbook blend of “Silicon Mountains” tech and finance with traditional Rocky Mountain industry.
Denver is in the North American West, specifically in the Upper Midwest’s mountain steppe zone. Geographically it sits at 39°44′ N, 105°0′ W (metro area). The city straddles the meeting point of the High Plains and the southernmost Rocky Mountains. Its elevation of exactly 5,280 ft is a well-known trivia fact. From almost any vantage you see the low-rolling Front Range foothills to the west and open plains to the east. The South Platte River (now dammed into the Cherry Creek Reservoir upstream) cuts through downtown, with tree-lined city parks along it.
Climatically, Denver experiences four distinct seasons. Its defining trait is sunshine: the city averages around 300 sunny days a year, among the highest of any U.S. city. Winters are cold by plains standards (average winter highs in the 40s°F, nights often in the teens°F). Snow is frequent, but often melts within days under the bright sun. Spring can be quick and stormy, with big swings in temperature (one night in the 20s°F can follow a day in the 60s°F). Summers are generally warm, with July and August high temperatures around 90°F (32°C) on average; late afternoon thunderstorms regularly cool things off. Fall sees comfortable days and chilly nights, plus some fall color in the river parklands. Humidity in Denver is low, so even on 90°F days the air feels dry. The overall impression is of a mild continental or even steppe climate: big diurnal temperature ranges, modest rainfall (~15 inches/year, mostly spring/summer), and brisk air year-round.
Denver was founded in 1858 during the Pike’s Peak Gold Rush. Prospector William Larimer staked a claim at Cherry Creek and laid out a townsite (initially called St. Charles or Larimer’s Town). It quickly grew as thousands poured into Colorado seeking fortune. By late 1859 it was consolidated as Denver City. The early boom brought ephemeral fortunes and disasters (looting, epidemics), but over time Denver solidified into Colorado’s main gateway city. In 1861, the Colorado Territory made Denver its territorial capital, and by 1876 (the year Colorado became a state) Denver secured its status as state capital.
Key milestones in Denver’s rise include the arrival of the railroads in the 1870s (making it a transport hub), and the silver mining boom. By the late 1870s, Teller and Gilpin Counties were sending mountains of silver through Denver, building a skyline of ornate Victorian buildings. One iconic symbol was Horace Tabor’s Tabor Opera House (opened 1879), a lavish seven-story opera house that signaled Denver’s late-19th-century confidence. Though the Silver Crash of 1893 hit the city hard, Denver had already grown into the mountain West’s major city.
The 20th century saw Denver diversify and modernize. Denver Airport (DIA) opened in 1995 far east of the city, and became one of the busiest airports worldwide – a sign of Denver’s national connectivity. Downtown Denver experienced a renaissance: Lower Downtown (LoDo) was revitalized in the late 1990s. A defining project was the restoration of Union Station around 2014, which turned a once-derelict train station into a vibrant transit hub, shopping area and hotel. This catalyzed the current boom of restaurants and lofts in that neighborhood. The 2008 Democratic National Convention (hosted in Denver) and the legalization of recreational marijuana in 2012 also put Denver in headlines. New sports stadiums (the Colorado Rockies’ Coors Field in 1995, the Nuggets’ Ball Arena in 1999, and Pepsi Center which became Ball Arena, hosting NBA and NHL teams) anchored the city’s cultural renaissance. In short, Denver’s timeline runs from wild-west mining camp, to Silver-Rush boomtown, to 20th-century energy and aerospace center, to 21st-century tech and tourism hub. The city’s ability to reinvent its downtown (as seen in LoDo’s rebirth) shows a continuing dynamism.
Denver’s culture is a blend of urban sophistication and outdoorsy Western lifestyle. The city’s residents are often proud of their active, health-focused way of life. It boasts a vast park system (over 200 parks and hundreds of miles of bike paths). Outdoor recreation is woven into daily life: residents might bike to work, ski or snowboard in winter, and hike or jog in the nearby mountains on weekends. “Mile-High” pride runs deep – a sense of independence and vitality that comes with mountain living. At the same time, Denverers have a friendly, laid-back demeanor. Neighbors are apt to smile and say “hi,” and dogs are a common sight in breweries and sidewalks.
Culinarily, Denver is known for its craft beer scene (over 300 breweries in the metro area) and quality farm-to-table cuisine. The city also has strong Mexican and southwestern food traditions, reflecting its Hispanic heritage. Denver embraces a progressive social climate – marijuana legalization, gay marriage, and a generally liberal political bent are widely accepted here. Festivals are a big part of local life: for example, each year Denver hosts the Great American Beer Festival (fall), one of the country’s largest beer expositions, and one of the nation’s biggest Cinco de Mayo celebrations. The Denver Film Festival (late October) and PrideFest (June) draw national attention. Smaller street fairs, art markets and music events occur almost every weekend in summer (the city uses Civic Center Park and others as festival venues).
Sports also define the vibe. Denver is one of the few U.S. cities with teams in all four major sports. On game days, especially Broncos football Sundays and Rockies baseball seasons, the atmosphere is festive (tailgate parties, orange jerseys, and friendly wagering between fans). Red Rocks Amphitheatre, just outside the city, contributes a concert-going culture: the mere mention of a Red Rocks show is part of local bragging rights.
Demographically, Denver is fairly young and well-educated. There is a significant international community (global tech workers, professionals). Churches and cultural centers reflect a mosaic of backgrounds (from Buddhist temples to Latino folk dance groups). As a newcomer-friendly city, Denver typically welcomes transplants with minimal fuss; most social circles are easy-going. The pace in Denver balances work and play: you’ll see well-dressed people at a tech startup midday, and that same night the streets buzz with casual strolls to food trucks or nightlife. All told, the city’s character is cosmopolitan but grounded in nature – urban amenities exist side-by-side with views of Pikes Peak or the Rockies, and this mix gives Denver an energetic but not frantic rhythm.
Denver’s top attractions span arts, nature, and sports. In the heart of downtown is the 16th Street Mall – a mile-long pedestrian promenade lined with shops, restaurants, and periodic street performers. This Mall (designed by architect I.M. Pei) offers free shuttle service along its length and ends near LoDo (Lower Downtown). Nearby Larimer Square (the city’s oldest block) is also popular: this historic block of Victorian buildings now hosts boutiques and trendy bars. A short walk away is Union Station, an ornate 1914 train depot transformed into a transportation hub and entertainment complex. Union Station houses a hotel, eateries, and frequent live music – it has become a social centerpiece of Denver’s reborn downtown.
Denver is rich in museums and cultural venues. The Denver Art Museum (DAM) is world-class, with a noted collection of American Indian and Western art. The Denver Museum of Nature & Science is a family favorite – it has dinosaur exhibits, space capsules, and an IMAX theater. These attractions sit adjacent to the city’s beautiful City Park, which also holds the Denver Zoo and an expansive formal Botanic Gardens (complete with a conservatory and Japanese garden). The Botanic Gardens alone draw visitors for its floral displays. Further south, the Denver Botanic Gardens Chatfield Farms (suburban) offers wetlands trails.
Sports venues are themselves attractions. Coors Field (home of the Colorado Rockies MLB team) has tours and a rooftop view of the mountains. Ball Arena (Nuggets NBA, Avalanche NHL) and Empower Field at Mile High (Broncos NFL) are major draws on game days – each stadium offers city skylines in the backdrop. Even when games aren’t on, these large sports complexes often host big concerts and events.
For outdoor adventure near Denver, Red Rocks Park & Amphitheatre is a must-see . Just 15 miles west of downtown, Red Rocks is a natural red sandstone outcropping that doubles as a legendary concert venue. Daytime visitors can hike its trails and tour the Colorado Music Hall of Fame there. Other nearby escapes include City Park (with paddleboats on the lake), Washington Park (garden strolls), and the Denver Botanic Gardens (sensory gardens).
Day trips from Denver make great use of its “gateway” position. Rocky Mountain National Park is 90 miles northwest (long day trip or overnight), and Mesa Verde NP to the southwest. North of Denver are the mountaintowns of Estes Park and Boulder (for hiking and quaint downtowns). To the west, ski resorts like Loveland and Winter Park are reachable in a couple of hours. Back in town, an evening outing to the Denver Union Station area or the Denver Performing Arts Complex (one of the largest outside New York) offers a taste of the city’s vibrancy. In short, Denver’s attractions are balanced between its urban parks, cultural institutions, sports magnetism, and the easy-access outdoor playgrounds beyond the city limits.
Denver International Airport (DIA) is the primary gateway, located about 25 miles northeast of downtown. It offers nonstop flights to nearly every major U.S. city (and dozens of international destinations). DIA is a major hub for United, Southwest, and Frontier. From the airport, travelers can take the RTD A Line commuter train directly into downtown Denver in about 40 minutes, or use taxis, shuttles and rental cars. The city also has several smaller airports (Centennial, Jeffco, and Rocky Mountain Metro) mostly for general aviation and private jets.
If arriving by road, Denver sits at the junction of I‑25 (north-south) and I‑70 (east-west). I‑25 connects Denver to Colorado Springs (south) and Fort Collins (north), while I‑70 runs through the mountains to ski resorts like Vail. Other highways (I-225, US 36, US 40) radiate out to the suburbs. There is no passenger train service directly into Denver’s city center, though Amtrak’s California Zephyr stops in Denver (behind Union Station). Bus connections from DIA via Greyhound or RTD also serve the metropolitan area.
Denver’s downtown and immediate neighborhoods are fairly walkable, especially the 16th Street Mall (with free shuttles) and the LoDo entertainment district. However, much of Denver is spread out, so driving or transit is often needed. The RTD transit system runs extensive bus routes throughout the city and suburbs. The light rail network (University of Colorado A Line, W Line, etc.) connects downtown with Union Station, Golden, Denver Tech Center, and airport. Taxis and rideshare (Uber/Lyft) are plentiful; bike-sharing systems operate in the warm months. Parking downtown can be expensive, but many city-center destinations are within walking distance once parked. Always keep an eye on parking meters and street-sweeping times. If driving, remember Denver is in Mountain Time, and sign distances are in miles, speed limits in MPH.
Basic Tips:
Currency & Payment: US dollars are used. Credit/debit cards are accepted almost everywhere. ATMs and currency exchange desks are common at the airport and in downtown.
Language: English is the dominant language, but Spanish is widely spoken due to Denver’s Hispanic community. You’ll also hear many other languages at tourist sites. Basic pleasantries in English (e.g. “thank you”) are appreciated.
Tipping: Standard U.S. customs apply (15–20% of the bill in sit-down restaurants; a few dollars per bag for bellhops; $1–2 per drink at bars).
Weather & Clothing: Denver’s weather can change quickly, especially in spring and fall. Layers are key. In winter, warm boots, coat and gloves are needed; in summer, carry a light jacket (mornings and evenings can be surprisingly cool) and an umbrella for passing thunderstorms. Sun protection (sunscreen, sunglasses) is important year-round due to the high altitude. Snow tires or chains may be required on mountain roads in winter; even in the city, check weather forecasts before driving.
Altitude: Denver’s high elevation means newcomers may notice shortness of breath climbing stairs. Stay hydrated and take it slow the first day.
Etiquette: Denverites are generally friendly and open-minded. A casual greeting (“hi, how’s it going?”) works well. Locals often share “Denver time” (arriving a few minutes late is usually okay). Safety is good, but as in any city, stay aware in crowded areas and don’t leave valuables visible in cars. Bicycle riders must obey traffic laws; pedestrians should use crosswalks and note that Colorado law gives vehicles the right of way when pedestrians are not at a marked crosswalk.
Miscellany: Denver’s electricity is 120V (North American standard), and the city runs on Mountain Time (UTC–7, MDT in summer). Note that altitude effects (including stronger UV radiation) are factors in Denver, and water fountains or refillable bottles are useful (water here is excellent due to mountain snowmelt).
With its mix of urban amenities and natural beauty, Denver is welcoming to all travelers. Whether you’re an international tourist or a U.S. visitor, you’ll find that the city’s friendly “mile-high” spirit and well-organized services help you navigate the city easily. From catching a performance at the Denver Center for the Performing Arts to hiking on a nearby trail, the city encourages both cultural exploration and outdoor adventure. A bit of advance planning on transport and weather will ensure a smooth stay in this vibrant and practical Western capital.
