Colorado What To Do›With Kids
Twenty things that genuinely hold a child's attention — plus the altitude problem that catches families out on day one, and how to avoid it.

How does altitude affect kids in Colorado?
Children are affected faster than adults, and it usually shows up as irritability, poor sleep and loss of appetite rather than anything dramatic. Sleep your first night at a lower elevation, keep everyone drinking more water than feels necessary, and save the most demanding activity for day three. If a headache with nausea will not resolve, the treatment is to descend.
Here is the arithmetic. The percentage of oxygen in the air never changes — it is about 20.9% everywhere. What changes is air pressure, and pressure is what pushes oxygen into blood.
At Denver's 5,280 feet, air delivers roughly 82% of the oxygen it does at sea level. At 10,000 feet, about 69%. That is not a small difference, and small bodies notice it sooner.
Families routinely land, drive straight to a mountain town at 9,000 feet, and spend day two wondering why everybody is miserable. Then they blame the trip.
None of this is a reason to avoid Colorado with children. It is a reason to plan the first 48 hours differently than you would anywhere else. Our full guide to reading a Colorado mountain day covers the physiology in more detail, including a working oxygen calculator.

Showing all 22
Estes Park & Grand Lake · High Country
Short, flat trails around lakes like Sprague and Bear are perfect for small legs, and spotting elk, marmots and chipmunks keeps kids engaged the whole way.
Book the park's timed entry ahead so you are not turned away with a car full of children.
Colorado Springs · Front Range
Paved, mostly level paths weave between towering red rocks, so strollers work and kids can run ahead safely. The visitor center helps explain how the rocks got there.
It costs nothing to enter, which makes an easy first-day outing.
Mosca · San Luis Valley
A giant sandbox under the mountains. Kids climb, roll and slide down dunes for hours, and in late spring Medano Creek turns the base into a beach.
Hot sand burns little feet in summer afternoons. Visit early or late and bring shoes.
Cortez · Western Slope
Climbing ladders into cliff houses makes history real for older kids. Younger ones can enjoy the overlooks and short walks on the mesa top.
Some tours involve tall ladders and tight spaces; check the age guidance when you book.
Morrison · Front Range
Kids love racing up the giant seating rows and spotting the huge rocks on either side. The visitor center and short trails make it a quick, free stop near Denver.
Great Sand Dunes · San Luis Valley
Hand a kid a sled at the top of a dune and watch them wear themselves out. Renting boards and sleds near Alamosa is simple, and even toddlers can ride the small slopes.
Denver · Front Range
Hidden passages, glowing rooms and buttons everywhere: it is built for curious kids. Teens dig into the storyline while little ones just explore.
Denver · Front Range
Dinosaur skeletons, mummies, a planetarium and space exhibits fill an easy day indoors, which makes it the perfect plan when afternoon storms roll in.
Morrison · Front Range
Kids can put their hands next to real dinosaur footprints pressed into the rock. Walking the road is free, and a guided shuttle is available for tired legs.
The rock layer called the Morrison Formation takes its name from the nearby town.
Boulder · Front Range
Hands-on weather and climate exhibits in a dramatic building on a mesa, free to enter, with easy trails out back for running off extra energy.
Glenwood Springs · Western Slope
A giant warm pool with room to splash and, in season, slides. When the weather turns, a hot springs afternoon saves the day for the whole family.
Salida & Buena Vista · High Country
Gentle family stretches with a licensed guide let kids feel the splash without the scary rapids. Ask outfitters about minimum ages.
Snowmelt sets the season; in dry years ask about current flows before booking.
Estes Park · High Country
In fall, elk wander right through town and the meadows. Kids can watch and listen to bugling from the safety of the car.
Cañon City · Front Range
Looking down through the gaps to a river far below gives kids a safe thrill, and the park adds rides and a gondola for a full day.
Rye · Front Range
A real castle with towers to climb and a dragon to find. Older kids will love it; keep a close hand on little ones on the open walkways.
Durango · Western Slope
A real steam train with whistles, smoke and canyon views makes a day trip feel like a storybook. Pack snacks for the ride.
Fruita & Grand Junction · Western Slope
Lots of short overlooks along the rim road mean quick stops between snacks, with huge red rock towers that kids find amazing.
San Luis Valley and statewide · San Luis Valley
Staying up late for shooting stars is a treat, and Colorado's dark sky parks make the Milky Way easy to spot even for first-timers.
Choose a night near the new moon, bring blankets and let eyes adjust for half an hour.
La Junta · Eastern Plains
A rebuilt adobe trading post where costumed interpreters bring the Santa Fe Trail to life. Kids can poke around rooms that feel lived in.
Calhan · Eastern Plains
Colorful clay towers and narrow paths make a fun, short exploration on the prairie. Stay on the trail and do not climb the formations.
Denver · Front Range
Family-friendly galleries and art activities make it an easy indoor stop, and the striking buildings are fun to look at from outside too.
Denver · Front Range
Trains to watch, space to wander and lots of food options under one roof. It is also where the airport train arrives, which makes an easy first stop.
Nothing matches those filters. Try clearing one.
By age
Keep it low and keep it short. Denver Union Station's great hall is free, indoors and endlessly interesting to small children — trains arrive, people move, and nobody minds noise. Red Rocks is free to walk and the scale alone does the work. The Denver Museum of Nature & Science has a dedicated discovery area.
Skip the fourteeners, obviously, and skip anything requiring a two-hour drive each way.
Primary school age is when Colorado clicks. At Dinosaur Ridge in Morrison, kids stand beside real Cretaceous footprints on a tilted rock slab, in the town that gave the Morrison Formation its name. Sliding down the Great Sand Dunes is tiring and totally new. The Durango & Silverton steam train follows an 1882 narrow-gauge line through a river canyon, a long day that kids remember.
The elk rut in Estes Park in September and October is free, spectacular and viewed from the car. Hundreds of elk, bugling at dawn and dusk. Keep your distance — a bull elk in rut is a 700-pound animal with a bad attitude.
Raise the intensity. Rafting the Arkansas through Browns Canyon, the Royal Gorge Bridge 956 feet above the river, mountain biking, or Meow Wolf Convergence Station, which is four floors of immersive art with a story hidden inside it.
Fourteeners become plausible around this age, provided everyone is acclimatised and you start before sunrise. Mount Elbert at 14,440 feet is the highest in the state and one of the more walkable.
Plan B
Afternoon storms are near-daily from mid-July into early September. A washed-out afternoon is normal here, so have the indoor list ready before you need it.
The other constant is the two o'clock rule. Colorado's summer storms build on a daily cycle you can plan around: mornings are reliably clear, afternoons are not. Do the outdoor thing first and hold the museum for later.
Families on a budget can camp for free on most Forest Service roads in Colorado's national forests. Colorado Camping Spots lays out where to go by region, and which sites have water and which very much do not.
Common questions
The family favorites are sledding the Great Sand Dunes, a day at the Denver Museum of Nature & Science, the Durango & Silverton steam train, Dinosaur Ridge's footprints just outside Denver, fall elk watching in Estes Park and the Royal Gorge Bridge, 956 feet above the Arkansas River.
Children are affected faster than adults, and it usually shows up as irritability, poor sleep and loss of appetite rather than anything dramatic. Sleep your first night at a lower elevation such as Denver or Colorado Springs before going higher, keep everyone drinking more water than feels necessary, and save the most demanding activity for day three. If a headache with nausea will not resolve, the treatment is to descend.
Very. Four national parks, a steam railroad, dinosaur fossils you can stand next to, dunes you can sled down and a free museum floor on atmospheric science all sit within a few hours of Denver. The main planning constraints are altitude on day one and driving distances — Denver to Durango is about six and a half hours, so pick one region rather than three.
The Denver Museum of Nature & Science in City Park has dinosaurs, gems and the Gates Planetarium. Meow Wolf Convergence Station is four floors of immersive art that works well for older children. Union Station's great hall is free to sit in, and Dinosaur Ridge in Morrison — with real Cretaceous footprints on a tilted rock slab — is about twenty minutes away and free to walk.
For many families it is the highlight of the trip. Rent a sled or board in Alamosa and ride North America's tallest dunes, about 750 feet high, until the kids are exhausted. The one real hazard is heat: on summer afternoons the sand can pass 150°F, so plan mornings or evenings.
Ski school is the obvious answer, and most Colorado resorts have one. Snowshoeing needs no lesson and costs roughly what a lunch at the lodge does, and hot springs round out the day. Glenwood Hot Springs, one of the biggest geothermal pools anywhere, sits right off I-70, which makes it the dependable plan when the weather changes.
Most national park fees are per vehicle, so kids usually ride along at no extra cost, and the National Park Service offers a free annual pass to fourth graders and their families. Rocky Mountain National Park also needs a timed entry booking from May 22 through mid-October 2026, with a $2 processing fee added to the entry charge.
Give it about a week in a single region. That leaves room for a low-elevation day to adjust, a national park visit and some unscheduled time. Squeezing the Front Range, the mountains and the Western Slope into less than a week means the kids spend their vacation strapped into a car seat.
