AI-generated summary

I've spent the last decade visiting all 50 states solo, and although there's something to love about each one, I ultimately chose to live in Colorado.

From the dramatic landscapes and national parks to Colorado's wine country, the state packs an incredible amount of diversity into its borders. And as a resident of over a decade, I like to think I know all the best places to go.

If I only had one day in Colorado, however, there are a few things I absolutely wouldn't miss. So, I decided to create the perfect, busy summer-day itinerary.

Here's how I'd spend one long — but unforgettable — day in Colorado.

Start the day in Aspen and wake up early to see the Maroon Bells at sunrise.

To start the day, I recommend going to the Maroon Bells — two bell-shaped mountain peaks that rise over 14,000 feet above sea level.

You'll need to make a $10 advance parking reservation before heading to the trailhead, which is located just about 15 minutes from Aspen. Once there, the viewpoint is a short walk away, with other hiking trails available to explore if you have time.

Watching the alpenglow, which is when a reddish glow appears on the summit before sunrise or after sunset, is something I never grow tired of. Plus, the reflection of the peaks in Maroon Lake is a gorgeous sight to take in.

Head into Aspen for breakfast at Swedish Hill Café.

After a bucket-list-worthy morning, it's time to head back into Aspen for breakfast at Swedish Hill Café, a hidden gem on the roof of the Aspen Art Museum. My go-to order is the lavender latte and avocado toast.

While eating, I love taking in the incredible view of the mountains from the rooftop. Plus, if time allows, I recommend heading downstairs to explore the museum — admission is free.

Drive over Independence Pass to Twin Lakes.

If you're visiting Colorado between late May and late October (the dates change slightly each year), I recommend driving Independence Pass from Aspen to Twin Lakes.

When it's open for the season, visitors can take in what I think is some of the most beautiful scenery in the country — towering peaks, alpine tundra, wildflowers, forests, and likely some snow.

There are plenty of places to pull off along the 32-mile stretch of road, including the short but impressive Grottos Trail.

Keep in mind, you'll only want to take on this portion of the trip if you're a confident driver, as there are some steep and narrow sections of the road.

Spend time recreating at Twin Lakes.

On the other side of Independence Pass lies one of my favorite recreation areas — Twin Lakes. The pair of high-elevation glacial-carved lakes is a stunning spot for picnicking, relaxing, and hiking.

Make sure to stop for a self-guided walking tour of the historic Twin Lakes Village, where you can see log cabins, browse the general store, and visit blacksmith shops and an old schoolhouse.

Just keep in mind there's a small day-use fee to access parts of the recreation area.

Next, grab a late lunch in Breckenridge.

After spending time in Twin Lakes, I recommend driving about an hour and a half to Breckenridge, which offers more of the stunning scenery you've come to expect.

The town really shines in the summer months, with great hiking and a quaint downtown full of local shops. I suggest stopping at Ohana for apparel and merchandise, and Mountainkind for goods from local artists and artisans.

When I'm hungry, I usually opt for lunch or happy hour at Aurum or Hearthstone.

End the day in Boulder, watching the sunset over the Flatirons.

From Breckenridge, you'll continue to drive just less than two hours to Boulder for sunset.

Head to Chautauqua Park to watch the sunset over the iconic Flatirons, or downtown to one of the rooftop restaurants like Avanti, Rosetta Hall, or Corrida for a drink and a great view.

After sunset, head to dinner at one of Boulder's many restaurants — like Stella's Cucina, the Boulder Dushanbe Teahouse, or Cozobi Fonda Fina — and head to one of the downtown hotels for a good night's sleep.
