Things To Do
In Colorado

A Colorado trip goes right or wrong on timing. The same pass that is a wildflower drive in July is under snow in March, and the canyon that is perfect in April is an oven in August.

So this page is organized by the calendar. For each season you get the places that are at their peak, what is happening around them, and the timing details that catch people out. The places are the same ones Coloradans send visitors to: four national parks, the big scenic roads, the hot springs, the odd roadside wonders and Denver's best indoor days.

Colorado is also bigger than people expect. Denver to Durango is roughly six and a half hours, and Denver to the Great Sand Dunes is about four. Match one region to your season and go deep, rather than chasing every place on this list in one week. For the full event calendar, see Colorado events month by month.

June to August

Summer: High Roads, Alpine Lakes And Festival Weekends

Everything opens and everyone arrives. It is the season of the longest days and the most rules, because this is when the reservation systems run. Two things shape every summer plan: afternoon thunderstorms that build almost daily from mid-July into early September, so summit early and be below treeline by two; and wildfire smoke, most common on the Western Slope in July and August.

Where to go

• Rocky Mountain National Park, Estes Park and Grand Lake. Alpine tundra, 355 miles of trail and the headwaters of the Colorado River.
• Trail Ridge Road, inside the park. The highest continuous paved road in any U.S. national park, with eleven miles above treeline. It is usually snowed shut from late October to late May.
• Mount Blue Sky Scenic Byway, from Idaho Springs. North America's highest paved road gains more than 7,000 feet in 28 miles to about 14,130 feet, and mountain goats and bighorn sheep are routine sightings. It reopened for Memorial Day weekend 2026.
• Maroon Bells, near Aspen. Two 14,000-foot peaks over Maroon Lake, among the most photographed mountains anywhere.
• Hanging Lake, Glenwood Canyon. A turquoise lake perched on a cliff, fed by Bridal Veil Falls, about 1.2 miles up with roughly 1,200 feet of climbing.
• Pikes Peak, Colorado Springs. 14,115 feet by cog railway, highway or a very long hike; Katharine Lee Bates wrote "America the Beautiful" after reaching the top in 1893.
• Durango & Silverton Railroad, Durango. A coal-fired steam train on an 1882 narrow-gauge line through the Animas River canyon. Plan the whole day.
• Bishop Castle, Rye. A stone castle with towers, iron catwalks and a dragon, built largely by one man, Jim Bishop, beginning in 1969. No admission.
• Rafting, still the top summer water activity, and dark sky stargazing at its best when the summer Milky Way rises over the San Luis Valley.

What is happening

June brings the Telluride Bluegrass Festival, the Food & Wine Classic in Aspen and the Pikes Peak International Hill Climb. July has the Greeley Stampede, the Cherry Creek Arts Festival and the Aspen and Vail classical seasons. August means Palisade peaches, the Rocky Mountain Folks Festival, Telluride Jazz and the Colorado State Fair. Details are in the music, food and drink and rodeo and fair guides.

September to October

Fall: Aspen Gold, Bugling Elk And Beer In Denver

September is Colorado's best month by a wide margin: settled weather, smaller crowds once school starts, the elk rut and the aspens. Color moves by elevation rather than by date. Passes above 10,000 feet peak in mid to late September, mid-elevation spots such as Kenosha and Guanella passes from late September into early October, and the Front Range holds on into mid-October. Drought years such as 2026 pull the whole sequence earlier and shorten it.

Where to go

• Kebler Pass, Crested Butte. Thirty miles of dirt road through what may be the largest connected aspen forest in North America, usually fine for a regular car when dry.
• San Juan Skyway, Durango, Silverton and Ouray. A 236-mile loop through the most dramatic mountains in the state, including the Million Dollar Highway, and the best fall color drive in Colorado.
• Elk rut in Estes Park, September and October at dawn and dusk. Hundreds of bulls bugle in the meadows; watch from your car and keep your distance.
• Maroon Bells at sunrise, when the aspens around Maroon Lake turn.
• Royal Gorge Bridge, Cañon City, a suspension bridge 956 feet above the Arkansas River that held the world height record for decades.
• The spring list works again as temperatures drop: Great Sand Dunes, Colorado National Monument, Black Canyon and Picketwire Canyonlands.

What is happening

Labor Day weekend is the Telluride Film Festival. September brings the Breckenridge Film Festival, the Meeker sheepdog trials and Palisade's Colorado Mountain Winefest. October has Estes Park's Elk Fest, the Great American Beer Festival in Denver and the Telluride Horror Show. Our home page keeps a dated what's on now list.

Things to do in Colorado with kids

The altitude hits children harder and faster than adults, and it usually shows up as crankiness and a bad night's sleep rather than anything dramatic. Plan low for the first day.

• Denver Museum of Nature & Science. Dinosaurs, gems, a planetarium, and a view of the whole Front Range from the west windows.
• Great Sand Dunes. Rent a sandboard in Alamosa. It is the single best kid activity in the state and it wears them out completely.
• Durango & Silverton Narrow Gauge Railroad. A coal-fired steam train on an 1882 route through a river canyon. Long day, worth it.
• Dinosaur Ridge. Real footprints they can stand next to, twenty minutes from Denver.
• Elk rut in Estes Park. September and October, dawn and dusk, from inside the car. Free and unforgettable.
• Royal Gorge Bridge. 956 feet above the Arkansas River. Terrifying in the good way.

What to do in Colorado when the weather falls apart

Afternoon storms and early snow are normal here. A washed-out day is not a lost day.

The itinerary I hand people: Clyfford Still Museum in the morning, walk across the plaza to the Denver Art Museum after lunch, drive twenty minutes out to Dinosaur Ridge when the light on the track slab is best, finish at Red Rocks whether or not there is a show. Mostly indoors, costs less than a lift ticket, and covers Abstract Expressionism, a Gio Ponti building, the Jurassic and 300-foot sandstone monoliths.

Outside Denver, the reliable bad-weather answer is hot springs. Glenwood, Steamboat's Strawberry Park, Ouray, Pagosa. Sitting in 104-degree mineral water while it snows on your head is arguably the best thing about winter in this state.

Two things determine whether a Colorado trip felt good in hindsight, and neither of them is the hike.

Food

Denver's restaurant scene stopped being a punchline about fifteen years ago and has been quietly excellent since. The concentration is in RiNo, LoHi and the Highlands rather than downtown proper. Green chile is the regional dish that actually matters here, and the Colorado version is its own thing — pork-based, thinner than New Mexico's, served over everything.

In mountain towns, the honest advice is to eat lunch big and dinner early. Resort town kitchens close earlier than you expect, and the good places book out on weekends in both peak seasons. If you are working through Denver specifically, our companion guide at Best Restaurant Denver goes deeper on neighborhoods and reservations than this page can.

Sleeping

Three tiers, and they are wildly different prices.

• Resort towns. Vail, Aspen, Breckenridge, Telluride. Expensive in both peak seasons, genuinely cheap in the April–May and October–November shoulder gaps.
• Gateway towns. Estes Park, Salida, Buena Vista, Ouray, Durango, Alamosa. Better value, more character, usually within an hour of the thing you came for.
• Camping. The budget tier: primitive sites along most national forest roads cost nothing, usually with a two-week limit in any four-week stretch. Campgrounds with water and toilets are booked on Recreation.gov, and the popular ones are gone months ahead, especially around big festival weekends.

If camping is the plan, start with Colorado Camping Spots, which breaks the state down region by region, and read our Leave No Trace guide before you go — especially the section on killing a fire in a drought year.

Four things people underestimate:

• Mountain driving is slower than the map says. Add 30% to any GPS estimate that crosses a pass. Construction, wildlife and slow trucks are constants.
• I-70 has a rhythm. Westbound Friday afternoon and eastbound Sunday afternoon are the worst four-hour blocks of the week, year-round, and dramatically worse during ski season. Leave at odd hours.
• Chain and traction law is real. CDOT activates restrictions during storms and the fines escalate sharply if you block the road. All-season tires with adequate tread usually satisfy the passenger vehicle traction law; check before the storm, not during.
• Some of the best roads are dirt. Kebler Pass, the Alpine Loop, much of the Eastern Plains. Rental agreements sometimes prohibit unpaved roads. Read yours.

For live conditions, cameras and closures, use COtrip.org or dial 511 from any phone in Colorado. Note that 411 is directory assistance, not travel information — a surprisingly common mix-up.

We break down all 26 designated routes, their seasonal closure windows and which ones need four-wheel drive on our Colorado scenic byways guide. For picking the month rather than the place, see the best time to visit Colorado.
