Five Days Through Colorado’s High Country: Denver to Maroon Bells
A five-day loop from Denver through Rocky Mountain highs to Aspen’s Maroon Bells—big views, smart logistics
On the third morning, you wake to a thin, bright cold that scrubs the air clean. Steam lifts off a river you’ll cross later that day; spruce-scented wind threads the bus windows as the van coasts up a shoulder of highway and the skyline of Denver shrinks behind you. What feels like a single, slow revelation is actually five distinct acts: city, alpine park, high passes, hot springs, and a finale framed by red sandstone. This small-group tour stitches them together over five days, trading the logistics and long drives for a curated loop through Colorado’s most photographable landscapes.
Trail Wisdom
Acclimate for the First Day
Spend the morning hydrating and moving slowly—altitude makes short walks feel harder; avoid overexerting on day one.
Layer Smartly
Temperatures swing; pack an insulating mid-layer and a windproof shell to handle sharp mountain gusts.
Footwear Choices
Trail runners with grippy soles work for most trails, but bring ankle-supporting boots if you plan steeper hikes.
Plan for Crowds at Maroon Bells
Arrive early for reflections and fewer people, or accept a later lakeside walk if the tour substitutes Dillon Reservoir in high season.

Conservation Note
Many areas visited are within national park or state-protected lands—stay on trails to protect alpine tundra and follow hot-springs etiquette to reduce runoff and contamination.
The route traces mining and railroad corridors that shaped Colorado’s 19th-century boom towns and later pivoted to tourism and outdoor recreation.
Seasonal Guide
spring
Best for: Wildflowers at lower elevations, Waterfalls from snowmelt
Challenges: Patchy snow on high trails, Variable road access
Spring brings rapid green-up and powerful runoff; expect some trail closures and chilly mornings.
summer
Best for: Full access to high passes, Warm days for soaking
Challenges: Afternoon thunderstorms, Peak visitor crowds
Summer is the easiest for high-elevation hiking, but afternoons often bring brief, intense storms—plan activities for early in the day.
fall
Best for: Aspen and aspen leaf color, Crisp, clear air for photography
Challenges: Early snowfall at elevation, Shorter daylight hours
Fall delivers some of the state’s best light and colors; aim for September to catch peak aspen season.
winter
Best for: Snow-covered vistas, Fewer crowds on scenic drives
Challenges: Road closures and heavy snow, Cold temperatures
Winter routes may change and some passes close; tours often pivot to lower-elevation alternatives or require snow-capable vehicles.
Photographer's Notes
What to Bring
Daypack (20–30L)Essential
Holds water, layers, snacks, camera, and essentials for variable conditions.
Insulating MidlayerEssential
A fleece or lightweight puffy keeps you warm during cool mornings and evenings.
Sturdy Trail ShoesEssential
Provide traction on rocky trails and comfort for multi-day walking.
Hydration System or Water Bottle (2L+)Essential
Altitude increases dehydration risk—carry ample water and drink regularly.
Common Questions
Do I need to be an experienced hiker to join?
No—most walks are moderate; you should be comfortable walking several miles and handling 1,000+ feet of elevation change on some days.
Is altitude sickness a concern?
Yes—altitude can affect anyone; hydrate, avoid alcohol the first day, and communicate symptoms to your guide.
Will I have time to soak in hot springs?
Yes—Glenwood Springs or a similar thermal pool is built into the itinerary for relaxation and recovery.
What weather should I expect?
Mountain weather changes quickly—expect sun, wind, and possible snow at higher elevations even in summer; pack layers.
Are park entrance fees included?
Policies vary—confirm with the operator; some tours include national park entrance fees while others ask you to cover them at the gate.
Can I bring a camera or drone?
Cameras are welcome; drones are restricted in national parks (and often in popular viewpoints), so plan to keep aerial gear grounded.
What to Pack
Sturdy trail shoes (support and grip), insulating mid-layer (warmth at elevation), water bottle or hydration system (prevent dehydration), sun protection (high-elevation UV is strong)
Did You Know
Rocky Mountain National Park contains over 355 miles of trails and includes Longs Peak, which rises to 14,259 feet.
Quick Travel Tips
1) Fly into Denver International Airport (DEN); 2) Allow time to acclimate before big hikes; 3) Book early for Maroon Bells access in fall; 4) Keep a flexible schedule for weather-related route changes
Local Flavor
After a day on the trail, head to Denver’s LoDo neighborhood or Union Station for craft beer and farm-forward plates; in Glenwood Springs, soak in century-old hot pools; in Aspen sample trout and locally sourced mountain fare—mountain towns favor hearty, seasonal cooking.
Logistics Snapshot
Closest airport: Denver International Airport (DEN); Typical trailhead/start: Estes Park for Rocky Mountain NP; Driving distance: Denver to Estes Park ~70–80 miles (~1.5–2 hours); Cell service: Good near towns, patchy in high country; Permits/passes: National Park entrance fee and possible timed-entry reservation (May–Oct).
Sustainability Note
This itinerary visits sensitive alpine and riparian areas—stay on established trails, pack out trash, avoid trampling wildflowers, and respect hot springs signage to protect water quality.
