Magnolia Non Motorized Trails Project

The best backcountry riding experience close to the city.

Magnolia Non-Motorized Trails Project

After years of solid partnership with the Boulder Ranger District (BRD), a $40,000 planning grant, and a ton of hard work, the US Forest Service (USFS) has approved an expansion of designated trails around the Nederland area that is on scale with the Buffalo Creek system.

In partnership with the USFS, BMA, the Nederland Area Trails Organization (NATO) and other stakeholders will spend several years bringing this vision to fruition. Learn more on the official USFS Magnolia Implementation page.

2019 Projects

Tall Stack (New 34)

Tall Stack will provide an important connection between Hobbit 3 and Lookout. About a mile long, this trail will create a bigger loop option around the lower West Magnolia trail system and also provide a smaller 2.5-3 mile loop incorporating Lookout and Hobbit 3. This trail will be built with help from the Rocky Mountain Youth Corps.

Short Stack (New 3)

Short Stack creates a connection from Hobbit 2 by Campsite 18 to Observatory trail on the hillside east of Rd 355. The trail is about a third of a mile long and creates an interloop in the trail system and allows trail users to bypass Rd 355. Short Stack was hand-built by volunteers and opened on 8/24/2019

Re-Root, Hobbit 1, and Observatory Intersection

Work will extend Hobbit 1 to the main parking lot and Observatory trailhead. Additionally, the trails require a reroute to reduce intersections from three to one for increased intuitive navigation, to discourage off trail use and improve navigability. BMA has contracted professional trailbuilders to help with this section and there will be machine work.

Sugar Magnolia and Aspen Alley Intersection Reroute

The final 450 feet of Aspen Alley ends in a drainage and water flow has caused a deep rut. Work will include realigning this trail segment slightly to the south and out of the drainage. BMA has contracted professional trailbuilders to help with this section and there will be machine work.

2018 West Magnolia Project Completed

In September and October, the Boulder Mountainbike Alliance completed trail area improvements to West Magnolia Trail System with the help of a National Wilderness Stewardship Alliance grant and generous donations to our trail fund.

What is the Magnolia Non-Motorized Trails Project?

The Magnolia Non-Motorized Trails Project is a a USFS-designated 44+ mile, non-motorized stacked loop trail system with improved connectivity and sustainability that conforms to environmental and recreation standards and includes:


  • New restrooms and expanded parking at Front Range and West Magnolia trailhead
  • Connectivity to the Toll Conservation Easement Trail, a 12-mile trail that will connect Magnolia to Jenny Creek and the traverse to Winter Park
  • Connectivity via singletrack trail to the Town of Nederland
  • Winter grooming opportunity for Nordic skiing and fat tire biking
  • Improved signage with an app-based trail map to assist in determining your ride
Why are some trails being obliterated?

The USFS determined that about 20+ miles of existing user-created social trails are redundant, unsustainable, on private property, in a wildlife sensitive area, and/or in critical habitat.

Where is it located?

The trail system is located just south/southeast/east of Nederland on 6,000 acres branching out from the Peak to Peak Highway in areas known as East Magnolia and West Magnolia.

When can I ride it?

The project will be completed over the course of the next seven to ten years. The area will be open to biking, with partial closures, depending on construction and safety issues, in limited areas.

What is the cost?

The estimates vary, but BMA believes the total cost to be between $1-2M.

How will it get accomplished? What is BMA’s role?
  • Through partnerships with the USFS, community groups such as the Nederland Area Trail Organization, Boulder Nordic Club, Boulder Area Trails Coalition, and others, money is being raised through grants and donations to accomplish the plan.
  • The USFS will contract with professional trail building companies, youth trail crews, and volunteer groups to build and improve the trail systems as proposed by the USFS.
  • BMA expects to fundraise up to 20% of the project costs over the next three to seven years, totalling $200,000 to $400,000.
Why is this important?
  • This change, initiated by USFS internal policy, is unavoidable. By collaborating constructively, good things can happen. Many of us know, love, and care for the trails and unique opportunities around Nederland – not just in the Magnolia area.
  • BMA wants to preserve what is awesome, address the problems identified by the USFS, and add new, even more awesome opportunities into the mix, creating a system that is easier to navigate and offers more large loops for riding.
  • Get involved. Join BMA, participate in the implementation process, volunteer or fundraise, and experience firsthand how BMA is engaging with the USFS, the citizens of Nederland and Boulder, and BMA’s 1000+ members.
How do I view the USFS documents of the final approved system?

Here are all the USFS docs for the final approved system.

Where can I find the final trail system map?

Here is the final trail system map.



  • ReRoot Trail Extension: ReRoot Trail’s eastern point ended on Haul Road, not the Magnolia Road trailhead at the Peak to Peak Highway. BMA built a new trail to extend to the existing ReRoot Trail at the first climbing turn on Aspen Alley.
  • Hobbit 2, Hobbit 3 & School Bus Trail Intersection: BMA cleaned up intersections so that Hobbit 2, Hobbit 3, and School Bus are all connected by singletrack trail. This made navigation more intuitive, and is part of the initiative of the Magnolia Non-Motorized Trail plan to reduce total intersections.
  • Hobbit 1, 2 and 3 improvements: NATO and BMA fixed steep, eroded sections making them fun and ride-able in both directions in keeping with the planned character for the Zone 1 trails close to town to be quick rides and easily accessible to the intermediate rider.
  • SuperVü: NATO built SuperVü in July 2018 from Clear Cut to the midpoint of Aspen Alley. The second half of the trail to the Magnolia Road trailhead will be completed in 2019.


  • BMA finished the Sugar Magnolia reroute.
  • BMA rerouted 400 feet of Sugar Magnolia that was on private property. It is now a handbuilt singletrack.
  • BMA turned the old Whoop-di road into a trail and connected it to the trailhead.
  • BMA worked on Aspen Alley area. Scope included rerouting the trail that was heavily damaged by logging trucks in the 2012-2013 Fuels Mitigation project, handbuilding new singletrack, and maintaining existing trails to link the Peak-to-Peak trailhead via sinuous singletrack to the work done by NATO on Lookout trail. Mountain Flyer featured this project in their Summer 2019 edition.


  • BRD released its final decision to approve the Magnolia Non-Motorized Trails Project.

2012 – 2014

  • BMA partnered with USFS and applied for a planning grant to help USFS create a management plan for the West Magnolia area (later expanded to include all of the Magnolia Trails by USFS).
  • BMA hired Contour Logic to conduct the work and the final draft was submitted to USFS.
  • A public engagement process was conducted as part of this planning effort that showed considerable alignment among local and regional riders in what they wanted out of the West Mag area for the future.
  • BMA continued with reroute of Sugar Magnolia to armor bottom of trail.


  • Wildland Restoration Volunteers (WRV) contracted with BRD to rebuild Sugar Magnolia with BMA as a volunteer partner.
  • Singletrack Trails was hired as the pro trail contractor. Five project days and 166 volunteers combined to move the trail mostly off private land and make it sustainable.


  • BMA and BRD applied for and secured a State Trails Planning grant ($40,000) and hired two trail consultants to develop a proposed management plan for the area.


  • Construction of Reroot began.
  • BRD requested BMA help fix the private property and erosion problems on Sugar Mag.
  • Partnering with Wildland Restoration Volunteers (WRV) as technical consultants, BMA helped create the new trail alignment.


  • Bicycle Colorado Trail Pros delivered initial plan to USFS BRD.
  • BRD requested BMA to work on Root Canal and Hobbits.


  • BMA volunteers began looking at system-wide issues in the West Mag area and mapping opportunities for trail improvements inlcuding better connectivity of system trails.
  • BMA signed contract with Bicycle Colorado Trail Pros to conduct trail improvements plan.


  • Boulder Mountain Bike Patrol signed service agreement with USFS BRD to patrol the West Mag area on all weekends between Memorial Day and Labor Day. This was the start of what is now the most successful bike patrol in the country, perhaps the world.

2004 & 2005

  • BMA conducted critical maintenance on trails that USFS deemed environmentally damaging in the West Mag area.


  • BRD finished Caribou-Magnolia Travel Management Plan
  • BMA advocacy efforts led to a hybrid of two decision alternatives that gave us the baseline of access to the Hobbits and other near-Nederland trails.
  • BMA stepped into a stewardship role helping the under-resourced BRD to develop signage and maps, conduct trail maintenance, and patrol the area for the safety of recreational users.
  • BRD’s plan identified that Sugar Magnolia and Reroot/RootCanal were crossing private property and were often straight fall line (20% slope in places) trails that needed to be moved onto public land and brought up to spec.


  • BMA worked with the USFS to make Magnolia trails legal to ride.
  • BMA advocated and gained approval for option that granted more trail access and increased connectivity.
