Sunol’s newest hiking trails offer scenic vistas and challenging terrain

After years of planning and trail work, an entirely new network of trails at Sunol’s Tyler Ranch Staging Area opened this winter. The move expanded Pleasanton Ridge Regional Park by 2,844 acres and added roughly 18 new miles of trails for use by outdoor lovers on foot, bike or horseback or with leashed dogs.

A recent hike provided ample evidence that these particular paths are not built for the faint of heart — major uphill stretches, but they lead to rewarding views.
