Interpark Regional Trails

Inter park Regional Trails are the more than 150 miles of paved trails that connect various Regional Parks. These linking trails, which go through cities and along major streams and channels, are in addition to the trails inside the parks. Use these trails to skate from Concord to Plea santon and beyond (Iron Horse Regional Trail), practice for a marathon by running from Niles Canyon in Fremont to the San Francisco Bay (Alameda Creek Trail), or ride your bike from Antioch to the west side of the Willow Pass in Concord (Delta de Anza Regional Trail).
