Route 1 The Fast Lane (I-70 to Glenwood Springs)

Best for: First timers, winter driving, or when you just need to get to Aspen.

This is the standard route, but “standard” in Colorado still means tunnels through mountains and river carved canyons.

Directions:
Denver → I-70 West → Exit 116 (Glenwood Springs) → CO-82 South to Aspen.

Drive time: 3 hours 20 minutes (no stops)

Where to Stop on I-70

• Idaho Springs (Exit 240) Grab a Beau Jo’s Colorado style honey wheat crust pizza. Also home to the Argo Mill and Tunnel tour.
• Georgetown (Exit 228) Walk the historic main street or ride the Georgetown Loop Railroad.
• Silverthorne/Dillon (Exit 205) Quick detour to the Sapphire Point Overlook for Gore Range views.
• Vail (Exit 173) Even if you don’t ski, the free parking structure in Vail Village is perfect for a coffee stroll.
• Glenwood Springs (Exit 116) Must do: Soak in the Glenwood Hot Springs Pool (world’s largest mineral hot springs). Then drive CO 82 toward Aspen.

Pro Tip Avoid the Tunnel Traffic

The Edwards Tunnel (near Vail) and Eisenhower Johnson Memorial Tunnels (near Loveland Pass) are traffic magnets on Friday afternoons and Sunday evenings. Leave Denver before 6 AM or after 7 PM to skip the crawl.

Route 2 Independence Pass (The Classic Scenic Stunner)

Best for: Summer driving, photographers, and anyone who wants to say “I drove that?”

Independence Pass is closed from late October to late May (typically reopens by Memorial Day). But when it’s open? It’s the most beautiful paved road in Colorado, period.

Directions:
Denver → I-70 to Exit 195 (Copper Mountain) → CO-91 South to Leadville → CO-82 South over Independence Pass → Aspen.

Drive time: 3 hours 45 minutes What Makes Independence Pass Special

• Highest point: 12,095 feet. That’s higher than most ski resort summits.
• Road width: Narrow. No guardrails in spots. Don’t bring a large RV or trailer.
• Ghost town: Stop at the Independence Ghost Town (mile marker 57). It’s a preserved 1880s mining camp.
• Grottos Ice Caves Just 5 miles east of Aspen. A short walk to blue ice formations (visible even in July).

Warning Not for Nervous Drivers

The switchbacks west of the pass summit are tight. You’ll share the road with cyclists and fearless Subaru drivers. Take it slow, pull over at designated turnouts, and do not stop in the middle of a curve for photos (locals will honk).

Key takeaway: If you drive Independence Pass in the morning, the sun is behind you heading west perfect lighting for photos.

Route 3 Top of the Rockies (Leadville & Twin Lakes)

Best for: History buffs, altitude lovers, and avoiding I-70 monotony.

This route adds 25 miles but drops you into Colorado’s highest incorporated city (Leadville, 10,152 feet).

Directions:
Denver → I-70 West to Exit 195 (Copper Mountain) → CO-91 South to Leadville → US-24 South to Twin Lakes → CO-82 West over Independence Pass → Aspen.

Drive time: 4 hours 30 minutes

Hidden Gems on This Route

• Leadville National Mining Hall of Fame Surprisingly fascinating. Real gold exhibits.

• The Matchless Mine Baby Doe Tabor’s tragic story. Free to walk around.

Where to Eat

• High Mountain Pies (Leadville) Hand tossed pizza at elevation. The “Ghost Town” pizza has green chile.
• The Golden Burro Café (Leadville) Old school diner. Get the cinnamon roll.

Route 4 Guanella Pass Scenic Byway (Wildlife Heaven)

Best for: Wildflower season (mid-July to mid-August) and moose spotting.

Guanella Pass connects Georgetown to Grant, but you’ll loop it as a detour off I-70.

Directions:
Denver → I-70 West to Exit 228 (Georgetown) → Guanella Pass Road (CR 381) South → US-285 South to CO-9 North to Alma → CO-82 over Independence Pass → Aspen.

Drive time: 4 hours 45 minutes

Why Guanella Pass is Worth the Detour

• Moose The marshy areas on the south side of the pass are moose magnets. Dawn and dusk are best.
• Bierstadt Trailhead One of Colorado’s easiest 14ers (14,065 ft). A 7-mile round trip if you want a hike before driving.
• No commercial traffic RVs and trucks are banned. Just you, the aspens, and silence.

Practical Tip Check Road Status

Guanella Pass is paved the entire way but closes during heavy snow (typically November to May). Check cotrip.org before leaving.

Route 5 The Secret Ferry Route (Cottonwood Pass)

Best for: Avoiding all I-70 traffic and experiencing something truly weird.

Yes, Colorado has a free cable ferry. It’s called the Buena Vista Ferry (technically a cable guided reaction ferry across the Arkansas River). Most locals don’t even know about it.
