Denver with Kids: 25 Best Family Activities and Trip Tips

Denver is one of the easiest major US cities to visit with children. The best things to do in Denver with kids include the Denver Museum of Nature & Science, the Denver Zoo, the Children’s Museum of Denver, Elitch Gardens theme park, and Red Rocks Park. Most family attractions cluster in City Park and downtown, so you can cover several in a single day without much driving. Plan on two to three days for the city, and budget extra time for altitude adjustment—kids feel 5,280 feet just as much as adults do.

Why Denver Works Well for Family Travel

Denver has an unusual combination for a big city: major museums and a theme park downtown, plus real mountains 30 minutes away.

That means you can do a rainy-day museum in the morning and a genuine hike in the afternoon. Very few US cities offer both without a long drive.

The city also has more than 200 parks within its limits and over 300 sunny days a year, so outdoor time is usually an option even in winter.

Altitude and Kids: What Parents Should Know

Denver sits at 5,280 feet. Children can be affected by altitude just like adults, sometimes more noticeably because they may not recognize or explain the symptoms.

Common signs in kids include headache, unusual crankiness, poor sleep, reduced appetite, and tiring quickly.

Practical steps that help:

• Push fluids constantly, more than you would at home
• Plan a slower first day rather than a packed one
• Skip high-elevation mountain trips on day one
• Use sunscreen year-round, since UV exposure is stronger at elevation
• Expect naps and bedtimes to be off for the first night or two

If symptoms are severe or include vomiting or confusion, descend to lower elevation and seek medical advice.

Best Museums and Indoor Activities

1. Denver Museum of Nature & Science

The strongest single pick for families. Full dinosaur skeletons, a walkable Egyptian mummy exhibit, a planetarium, and a fifth-floor view toward the Front Range.

Located in City Park. Plan on at least three hours.

2. Children’s Museum of Denver at Marsico Campus

Purpose-built for younger children, roughly ages 0 to 8. Hands-on exhibits include a climbing structure, a water play area, and an art studio.

Best for toddlers and early elementary ages.

3. Downtown Aquarium

A large aquarium with a shark tank, a flooded rainforest exhibit, and a restaurant where you eat beside the main tank. There is also a small ride and mini-golf area.

4. History Colorado Center

More engaging than most state history museums, with interactive exhibits including a simulated ski jump and hands-on pioneer displays.

5. Wings Over the Rockies Air & Space Museum

Housed in a former hangar with dozens of aircraft. Good for older kids interested in planes and space.

6. Denver Art Museum Family Programs

The museum runs dedicated family spaces and drop-in art activities, which makes an art museum genuinely workable with children.

7. Butterfly Pavilion

In nearby Westminster, this is a tropical conservatory where kids can hold a tarantula and walk through free-flying butterflies.

Best Outdoor Family Activities in Denver

8. Denver Zoo

Set inside City Park, one of the most-visited zoos in the country. Easy to combine with the Museum of Nature & Science on the same day.

9. City Park

Beyond the zoo and museum, the park has playgrounds, paddle boats on Ferril Lake in summer, and the classic downtown-and-mountains view.

10. Washington Park

Two lakes, big open lawns, and a well-equipped playground. Popular with local families on weekends.

11. Red Rocks Park

Free during daylight hours. Kids can climb the amphitheater steps, and the Trading Post Trail is an easy 1.4-mile loop through the rock formations.

12. Confluence Park

Where Cherry Creek meets the South Platte River. Shallow water and small rapids make it a summer favorite for wading and tubing.

13. Elitch Gardens

A combined theme park and water park located right downtown, which is rare for a major city. Rides span toddler-level to full roller coasters.

14. Denver Skate Park

One of the largest free public skate parks in the country, near Confluence Park. Fun to watch even if your kids do not skate.

15. Four Mile Historic Park

A working historic farm inside the city with animals, wagon rides, and living-history demonstrations.

Best Family Day Trips from Denver

16. Dinosaur Ridge, Morrison

About 20 minutes from downtown. Real dinosaur footprints and bones are visible in the exposed rock face along a walkable road.

Excellent for dinosaur-obsessed kids and requires very little hiking.

17. Georgetown Loop Railroad

Fifty minutes west. A narrow-gauge steam train that runs a spiral route between Georgetown and Silver Plume, crossing a high trestle bridge.

Consistently one of the best family activities in the mountains.

18. Idaho Springs

Forty minutes west. Hot springs, an easy walk to Bridal Veil Falls, and a compact main street. Good for a first mountain trip with kids.

19. Evergreen Lake

Forty minutes. Paddle boats in summer, ice skating in winter, and a flat lakeside trail that works with strollers.

20. Boulder and Pearl Street Mall

Forty-five minutes. Street performers on the pedestrian mall, plus a dedicated children’s play area and easy trails at Chautauqua Park.

21. Golden

Twenty-five minutes. Clear Creek runs through downtown, and families tube and wade there in summer.

22. Rocky Mountain National Park

About 1 hour 35 minutes via Estes Park. The Bear Lake area offers short, flat walks with big scenery. Reserve a timed-entry permit in peak season.

23. Waterton Canyon

Thirty-five minutes. A wide gravel path along the river where bighorn sheep sightings are common. Stroller and bike friendly.

24. Castlewood Canyon State Park

Fifty minutes southeast. An easy waterfall walk and dam ruins, with far fewer crowds than the mountain parks.

25. Cave of the Winds, Manitou Springs

About 1 hour 20 minutes south. Guided cave tours plus above-ground adventure activities for older kids.

Denver with Kids by Age Group

Suggested 3-Day Denver Family Itinerary

Day 1—Take it easy (altitude adjustment) Morning at City Park. Denver Museum of Nature & Science after lunch. Early dinner and an early night. Avoid mountain elevation entirely on day one.

Day 2—Downtown and downtown parks Union Station, and the 16th Street Mall in the morning. Downtown Aquarium or Elitch Gardens in the afternoon. Dinner at Denver Central Market, which has enough variety to satisfy picky eaters.

Day 3—Get to the mountains. Drive to Red Rocks in the morning for the Trading Post Trail. Continue to Idaho Springs or Georgetown for lunch and the railroad. Return by early evening.

Practical Tips for Visiting Denver with Kids

Book the Georgetown Loop Railroad in advance. Summer weekend departures sell out.

Pack layers, always. A 75-degree afternoon can drop 30 degrees after sunset, especially in the mountains.

Bring more snacks and water than you think you need. Altitude increases both thirst and hunger, and mountain-town food service can be slow at peak times.

Plan outdoor activities for mornings in summer. Afternoon thunderstorms are common June through August.

Use the free MallRide downtown. It saves a lot of tired kids walking along the 16th Street Mall.

Check for timed-entry requirements. Rocky Mountain National Park requires advance reservations during peak season.

Flying Into Denver with Kids

Denver International Airport is about 25 miles northeast of downtown and served a record 82.4 million passengers in 2024, making it the third-busiest airport in the United States.

A few things that make the airport easier with children:

The A Line train runs from the terminal to Union Station in roughly 37 minutes. Kids generally prefer it to sitting in traffic, and it avoids car seat logistics if you are not renting a car.

The terminal murals by Leo Tanguma and the blue mustang sculpture outside are genuinely interesting to older kids during a layover.

If you are driving to the airport and leaving your car, on-airport rates run from $7 per day at the 61st & Peña lot up to $28 per day in the East and West garages. Off-airport lots often price below that and include shuttle service, which can be easier with luggage and strollers.

For a week-long family trip, review DIA’s long-term parking options in advance. For shorter visits, DIA short-term parking is usually simpler. Compare current DIA parking rates before you book.
