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 network was in poor condition with failing steps, redundant social trails that contributed to erosion and loss of sensitive habitat, and a lack of 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, and provide 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 reduced the scope of work in order to complete substantial improvements with the funding we have committed. We have also made efforts to seek additional grant funding to help to complete the full project scope. Potential funding sources included the Recreational Trails Program, an additional Habitat Conservation Fund grant and the federal Land and Water Conservation Fund.
