The Experience

High on the Colorado high country, riders gather in Durango before a shuttle climb to Molas Pass where the trail unfurls into spruce, fir, and wide alpine bowls.

Before You Go

Acclimatize before you ride

Spend a day in Durango or at moderate elevation to reduce altitude effects; breathing feels heavier above 9,000 ft.

Start early to beat storms

Afternoon thunderstorms are common—plan to be off exposed ridges by midday and carry a lightweight shell.

Go tubeless or carry extra tubes

Rocky singletrack and high-mileage days increase puncture risk; tubeless tires with sealant reduce stoppages.

Know your braking and line choice

Technical descents require controlled braking and confident line selection—practice on similar terrain before this trip.

Conservation Note

High alpine meadows are fragile—stay on singletrack, pack out waste, and minimize campsite impact; group size limits and Leave No Trace practices help protect the corridor.

The San Juan Mountains were heavily prospected in the late 19th century; mining roads and towns like Durango and Silverton shaped early access and remain cultural touchstones.

Common Questions

What is slackpacking and how does it work here?

Slackpacking means guides shuttle your overnight gear between camps so riders carry minimal daily essentials—water, tools, and layers—while heavier items are transported for you.

How fit do I need to be for 17–21 miles daily at altitude?

You should have strong endurance and experience with sustained climbing; prior multiday rides or regular long rides at moderate intensity help ensure comfort on this trip.

Are bikes and helmets provided?

This operator typically requires riders to bring their own bikes and helmets; check the booking link for rental options or shuttle policies if you need gear.

What about weather and cancellations?

Afternoon storms are common; the operator may adjust itinerary for safety. Cancellation policy applies—full refund if canceled 6+ days prior, 50% between 2–6 days.
