Trail Stewardship & Maintenance
Rehab, erosion control, drainage, and safety upgrades on existing trails — keeping Turnagain Pass rideable, hikeable, and sustainable for the long haul.
Girdwood, Alaska · Fiscally Sponsored by Girdwood Inc.
Turnagain Pass is Alaska's wildest playground.
Mountain biking is how we prove it.
We steward, maintain, and champion sustainable, multi-use trails across Turnagain Pass — turning world-class terrain into a four-season destination for riders, skiers, hikers, and the businesses and families who call Alaska home.
Why we exist
Great trails don't happen by accident.
Turnagain Trails Alliance stewards, maintains, and thoughtfully expands sustainable, multi-use trail infrastructure across Turnagain Pass and the surrounding National Forest — built by mountain bikers, open to everyone.
We're the organized voice for the riding community and a trusted partner to the U.S. Forest Service and other land managers: coordinating volunteer trail crews, applying real trail-building craft, and pushing forward new singletrack the right way — sustainably, incrementally, and built to last.
We believe world-class recreation infrastructure isn't a nice-to-have for Alaska — it's economic development. It's why people stay, why families put down roots, and why companies choose to build here.
Our Vision
Turnagain Pass as a globally recognized model for sustainable, four-season recreation — where world-class trail systems, protected landscapes, and diverse user groups thrive together, strengthening the community and respecting the land that makes it all possible.
The terrain
One pass. Every season. Zero excuses.
Summer
Ride
Flowing, purpose-built singletrack through alpine terrain most riders only see in magazines — minutes from the Seward Highway.
Fall
Hike
Trail systems shared by hikers and trail runners, designed to spread the love without wrecking the tread.
Winter
Ski & Ride
Legendary backcountry access shared thoughtfully across ski touring, snowmachine, and human-powered users.
Year-Round
Show Up
A destination worth visiting twelve months a year — and worth investing in twelve months a year.
What your support builds
Four ways we move dirt (and the mission forward)
Volunteer Trail Crews
We organize, train, and lead the work parties — turning community enthusiasm into real trail miles, and giving land managers one reliable partner to call.
New Trail Development
Thoughtful, incremental, agency-approved expansion of mountain bike-oriented singletrack — designed to best-practice standards from day one.
Multi-Use, Four-Season Access
Trail systems built to share — supporting skiers, hikers, and other non-motorized users alongside the riding community, year-round.
Join the build
Three ways in.
Volunteer
Swing a Pulaski, haul rock, or just show up with good energy. No experience required — we'll teach you real trail craft on real trail.
