Twin Peaks Trails Improvement Project

Twin Peaks Trail and hikers


Twin Peaks is one of the most-visited natural areas, with stunning 360-degree views of the city and surrounding Bay Area. The Twin Peaks trail is in poor condition with failing steps and guardrails, redundant social trails that contribute to erosion and loss of sensitive habitat, and the trail system lacks trail identification and wayfinding signage.

Scope of Work

The Twin Peaks Trail Restoration project will improve the main spine trail, repair existing trails and steps, eliminate social trails, provide erosion control measures, restore native plants and provide trail identification and wayfinding signage. These measures will improve public safety, reduce erosion, and help preserve adjacent habitat. As part of the “Creeks to Peaks” project, a new trail segment adjacent to Twin Peaks Boulevard but off the roadway will extend southward and connect to Portola Avenue. In addition to providing greater pedestrian safety this new trail segment will complete the regional trail connection to Glen Canyon Park and help to complete the Creeks to Peaks Trail.

Twin peaks is also in the process of getting an update to its current roads to increase the accessibility of trails and improve pedestrian safety. We would love your input on the new design, for more information regarding the Twin Peaks Figure 8 Redesign Project click here.


The Twin Peaks Trails Improvement Project is funded by the 2008 Clean and Safe Neighborhood Parks Bond.  The Project is also supported by two Habitat Conservation Fund grants:

  • 2010 Habitat Conservation Fund (“Twin Peaks Trails Improvements”) grant: $131,041
  • 2013 Habitat Conservation Fund (“Creeks to Peaks”) grant (for trail improvements at Glen Canyon Park as well as at Twin Peaks): $130,000

Due to increasing construction costs and knowledge gained through completion of four previous bond-funded trails improvement projects, we are seeking additional grant funding to help to complete the project.  Potential funding sources include the Recreational Trails Program and the Habitat Conservation Fund.
