Colorado Summer Bucket List: 10 Unforgettable Adventures
Views from James Peak, a 13er
Summer in Colorado is my favorite time of year. Nearly all of the activities in this post were done July through September, and given this relatively short window I tend to pack in as many summer adventures as I can. Wildflowers blanket alpine meadows, crisp mornings lead into golden evenings, and adventure waits around every corner. Whether you're planning your first trip to the Rockies or a local looking for some fun road trip ideas with your friends and family, this guide covers 10 unforgettable experiences that capture the soul of a Colorado summer—with detailed tips and recommendations to help you plan.
1. Soak in a wild hot spring after a long hike
Conundrum Hot Springs
One of the most iconic wild hot springs in the state is Conundrum Hot Springs, located in the Maroon Bells-Snowmass Wilderness near Aspen. It's a 17-mile roundtrip hike with significant elevation gain, but the reward is soaking in steaming natural pools surrounded by 14,000-foot peaks.
Permit Required: You must reserve a permit for overnight stays through Recreation.gov.
Tip: Start early and pack out everything (yes, even human waste). The trail begins at Conundrum Creek Trailhead just outside Aspen.

2. Go on a backpacking trip
Backpacking the Four Pass Loop
Colorado has no shortage of breathtaking multi-day treks. Here are three stunning areas to explore:
Four Pass Loop (Maroon Bells-Snowmass): 28 miles of alpine lakes, wildflower fields, and dramatic passes. Start at the Maroon Lake Trailhead outside Aspen.
Pawnee-Buchanan Loop (Indian Peaks): About 27 miles starting near Brainard Lake, this less-crowded route features forested valleys and scenic ridgelines.
Chicago Basin (Weminuche Wilderness): Accessible via the Durango & Silverton Narrow Gauge Railroad. Take the train to Needleton and backpack into remote, goat-filled basins surrounded by 14ers.

3. Try outdoor rock climbing
Boulder Canyon
Never climbed outside? Colorado is a great place to learn. Hire a local guide or join a group lesson to get started safely. If you want to build skills before heading to the crag, consider taking an intro class at an indoor climbing gym.
Where to Go Outdoors: Boulder Canyon, Clear Creek Canyon (Golden), and Shelf Road near Cañon City are all beginner-friendly.
Gym Options: The Spot (locations in Boulder and Denver) offers intro to belay, top rope, and lead climbing classes that are perfect for first-timers.
Guiding Services: Check out companies like Colorado Mountain School or Denver Mountain Guiding for half- and full-day climbing experiences.
4. Visit a national park (or all 4!)
Sunrise in Rocky Mountain National Park
Colorado is home to four incredibly diverse national parks:
Rocky Mountain National Park: Alpine lakes, elk herds, and over 350 miles of hiking trails. Base yourself in Estes Park or Grand Lake.
Great Sand Dunes: Towering dunes backed by 13,000-foot peaks. Try sandboarding or stargazing. Stay in Alamosa or camp at Piñon Flats Campground.
Mesa Verde: Explore ancient cliff dwellings and archaeological sites. Lodging is available in Cortez or inside the park.
Black Canyon of the Gunnison: Sheer cliffs and dramatic views make this a hidden gem. Nearby Montrose is your best base.
5. Drive Trail Ridge Road
Trail Ridge Road
Trail Ridge Road is the highest continuous paved road in the U.S., topping out at over 12,000 feet. Open seasonally (typically late May to October), it connects Estes Park and Grand Lake through Rocky Mountain National Park.
Start: From Estes Park, enter the park via the Beaver Meadows Entrance.
Don’t Miss: Alpine Visitor Center, Gore Range Overlook, and the Tundra Communities Trail.
Tip: Check road conditions at NPS.gov before heading out.
6. Camp in an apple orchard at Big B’s
Big B’s Campground
For a unique overnight experience, camp at Big B's Delicious Orchards in Hotchkiss. Pitch a tent or car camp among the apple trees, enjoy live music, sip local cider, and browse the farm store.
Reservations: Book in advance at bigbs.com.
Nearby Attractions: Paonia wineries, Black Canyon of the Gunnison, and Gunnison River kayaking.
7. Paddleboard on Lake Irwin
Lake Irwin
Located just outside Crested Butte, Lake Irwin offers calm waters, alpine scenery, and easy access for paddleboarders and kayakers.
Access: Take Kebler Pass west from Crested Butte, then turn onto Forest Road 826.
Morning Tip: The lake is often glassy at sunrise. Grab coffee from Camp 4 Coffee and breakfast from Butte Bagels before heading out.
8. Soak up wildflower season
Beautiful wildflowers near Crested Butte/Aspen, August 2023
Colorado's wildflowers peak mid-July through early August in the high country. Top spots include:
Crested Butte: Known as the Wildflower Capital of Colorado.
Yankee Boy Basin: Near Ouray, offers vibrant blooms with dramatic mountain backdrops.
Indian Peaks Wilderness: Moderate hikes like Lost Lake or Mitchell Lake are packed with color.
Leave No Trace Tip: Stay on trail, don’t pick flowers, and avoid trampling delicate areas.
9. Hike a 14er
Views from Huron Peak, 14,012’
Colorado has 58 peaks over 14,000 feet, and summer is the ideal season to try one. These are great beginner-friendly options:
Mount Bierstadt: Near Georgetown, 7.2 miles RT with a well-maintained trail.
Quandary Peak: Near Breckenridge, 6.6 miles RT. Requires a parking reservation.
Handies Peak: Accessed via American Basin in the San Juans. Shorter at 5.5 miles RT and incredibly scenic.
Safety Note: Always start early to avoid afternoon thunderstorms and bring layers, at least 3L of water, and navigation tools.
10. See a concert at Red Rocks Amphitheater
Red Rocks Ampitheater
Red Rocks is the most iconic music venue in the country. I saw Lord Huron there last summer and it was absolutely magical—watching the sun set and the stars come out as music echoed through the red sandstone walls.
Location: Just outside Morrison, ~30 minutes from Denver.
Bonus: Arrive early to hike the Trading Post Trail before the show.
Tickets: Check the schedule and grab tickets at redrocksonline.com.
