LoBo Regional Trail Project


The LoBo Regional Trail is a 12-mile planned trail that joins trail systems in Gunbarrel, Niwot, City of Boulder Open Space, and County Open Space Properties connecting the City of Boulder with the City of Longmont.

The primarily soft-surface LoBo Regional Trail was identified in the 2003 Regional Trails planning process as preferable to a hard surface connection originally planned to be directly adjacent to the Diagonal Highway. Instead, some spot improvements to the shoulders along the Diagonal Highway were identified for a hard-surface connection for bicyclists with the LoBo Trail serving as a meandering connection for both recreational and commuting use.

Additional Trail Information

Additional trail information is located through the Parks and Open Space Department.
