Keep In Mind

  • The Anne U. White Trail follows the Fourmile Canyon Creek and crosses the creek numerous times.
  • Bikes and horses are not allowed.
  • Limited street parking in designated areas only. Please respect the neighbors.

Management Plan Amended

On Dec. 13, 2018, the Board of County Commissioners approved an amendment to the Fourmile Canyon Creek Park Management Plan to allow for expansion of the parking area that incorporates the following considerations:

  • Parking capacity may be expanded to accommodate up to 30 vehicles (at least 15 to 20 vehicles seem feasible).
  • Flood resilience should be a significant component of the design (e.g., 100-year flood design, boulder toe wall, etc.).
  • Stream restoration is an important component of the project. Consideration should be given to supporting montane riparian ecosystem functions in the overall design.
  • A permanent restroom facility may be constructed assuming a suitable location can be permitted.
  • The Anne U. White Trail shall be designated for pedestrian use only.
  • A plan for managing parking and other safety and enforcement concerns on Wagonwheel Gap Road during periods of high visitation shall be developed in coordination with the Transportation Department, law enforcement, the local fire district, and neighboring land owners prior to reopening the trail.
