Families tend to over-plan Denver. The city's best children's experiences are within a few miles of each other, and the altitude, strong sun and summer afternoon storms reward a gentler pace. A good rule is one big thing in the morning, a park or pool in the afternoon and an early dinner. This guide groups ideas by age and weather so you can mix and match.
The big four for families
Denver Museum of Nature & Science
The single best family stop in the city. Dinosaurs, mummies, gems, a hands-on discovery area for young children, space exhibits and a planetarium can fill a whole day. Arrive at opening and do the most popular halls first. Parking is on site, and City Park outside is perfect for a picnic break.
Denver Zoo
Across City Park from the museum, the zoo spreads over a large campus with an elephant habitat, big cats, primates and a train ride and carousel for extra fees. It is a lot of walking, so a stroller or wagon helps even for kids who have outgrown them at home. Weekday mornings are calmest.
Children's Museum of Denver at Marsico Campus
Aimed at babies through early elementary ages, with climbing structures, water play, a pretend grocery and fire station, and outdoor play areas. It sits near the South Platte River close to Confluence Park and the Downtown Aquarium.
Denver Botanic Gardens
The Mordecai Children's Garden, built on top of the York Street parking structure, has a stream, a mountain-themed play area and hands-on activities. Summer brings family programs and evening concerts, which are ticketed separately.

Animals, in and around the city
- Downtown Aquarium: indoor aquarium with a restaurant inside, near the river.
- Rocky Mountain Arsenal National Wildlife Refuge: a free wildlife drive northeast of the city where bison, deer and prairie dogs are commonly seen. See our refuge guide.
- Genesee Park bison: a city-owned herd viewable from overlooks just off I-70 in the foothills. Details are in our Denver Mountain Parks guide.
- Butterfly Pavilion: an insect and butterfly center in the northern suburb of Westminster, a good half-day stop with small children.
Splash spots and summer cool-downs
Denver summers are hot in the afternoon and dry. Water helps. Confluence Park's gravel beach and shallow edges are popular once spring runoff slows; always supervise closely, as river currents change quickly. Many city recreation centers have pools, and Denver's parks include splash pads in several neighborhoods. Elitch Gardens' water park is included with park admission in season. Clear Creek in Golden is another favorite for wading, again with close supervision.
Mountain creeks are cold and can be fast, especially in May and June. Keep young children within arm's reach, put life jackets on weaker swimmers and stay out when flows look high or the water is murky.
Rainy, snowy or too-hot days
Indoor options are plentiful: the Museum of Nature & Science, the Downtown Aquarium, the Children's Museum, Wings Over the Rockies, the History Colorado Center, the Denver Central Library's children's area and Meow Wolf Convergence Station. Several of these cluster near Confluence Park and the Golden Triangle, so you can combine two on a stormy day.
Easy family hikes
- Red Rocks Trading Post Trail: a 1.4-mile loop through red rock formations, with stairs and some climbing.
- Dinosaur Ridge: a paved walk past dinosaur tracks and bones, next to Red Rocks.
- Chautauqua meadow in Boulder: wide paths with Flatiron views.
- Garden of the Gods Central Garden Trail: a paved loop among towering rock fins in Colorado Springs.
Altitude, sun and practical tips
- Hydrate early. Start pushing water on the flight or drive in. Dry air means kids lose fluid quickly.
- Keep day one light. Mild altitude symptoms in children often look like crankiness, poor sleep or a headache.
- Sunscreen and hats. UV exposure is stronger at elevation, even in winter.
- Layer up. Mornings and evenings can be cool even in July; mountains are colder still.
- Plan for storms. Summer thunderstorms often roll in by mid-afternoon. Schedule outdoor activities for mornings.
- Book timed tickets. The Museum of Nature & Science shows, the Botanic Gardens and Meow Wolf use timed entry; buying ahead avoids disappointment.
Saving money as a family
The Denver Art Museum is free every day for visitors 18 and under. Major museums and gardens hold free days through the year, often with advance reservations. City parks, trails, Union Station and the free 16th Street shuttle cost nothing. Packing a picnic for City Park or Washington Park saves money and keeps restless kids moving.
Frequently asked questions
What is the best thing to do in Denver with toddlers?
The Children's Museum of Denver at Marsico Campus is designed for young children, and the Denver Zoo, the Mordecai Children's Garden at the Denver Botanic Gardens and the shallow edges of Confluence Park in summer all work well for toddlers. Keep outings short and build in naps.
Is Denver good for kids on a rainy day?
Yes. The Denver Museum of Nature & Science, the Downtown Aquarium, the Children's Museum, Wings Over the Rockies Air & Space Museum and Meow Wolf Convergence Station are all indoors. Meow Wolf requires an adult with anyone under 16.
Do children get altitude sickness in Denver?
Some do, usually mildly. Children may show it as fussiness, poor sleep or loss of appetite. Give plenty of fluids, keep the first day relaxed, and talk to a pediatrician before the trip if your child has heart or lung conditions. Symptoms that worsen are a reason to seek care.
Are there free things to do in Denver with kids?
Many. City parks and playgrounds, the creek trails, Union Station, the State Capitol tour for older children, the Rocky Mountain Arsenal wildlife drive and daily free admission for youth at the Denver Art Museum all cost nothing.
