Weathered structures and remnants of mining history still dot the valley, creating a hauntingly beautiful glimpse into Colorado’s Wild West past.
History enthusiasts should definitely pause here.

Although often overshadowed by Red Mountain Pass, Coal Bank is stunning in its own right.
Nearby, outdoor enthusiasts can access the popular Engineer Mountain Trail, a favorite among hikers and mountain bikers.
If you love alpine hiking, consider adding extra time here.
Bonus Detour: Don’t Skip Telluride
No San Juan Skyway road trip is complete without visiting Telluride.
Originally established as a mining camp in 1878, this world-famous mountain town combines Old West charm with breathtaking scenery.
Driving down Telluride’s historic Main Street feels like entering a movie set.
And the best attraction lies just beyond town.

At the end of Telluride Valley, you’ll find the tallest free-falling waterfall in Colorado:
Bridal Veil Falls.

A relatively short 2-mile roundtrip hike brings visitors to the base.
