The park units listed below have completed a comprehensive Roads and Trails Management Plan (RTMP). The purpose of a Roads and Trails Management Plan is to provide guidance for establishing and maintaining California's trail systems. This includes integrating state parks’ trails-related program efforts as much as possible with federal, local government agencies, and private organizations’ trail systems, their planning, funding, development, operation, and maintenance. Follow the links below for details about a specific RTMP.
