2021 Map of Isabel Valley
USGS Topo · Published 2021About this map
Isabel Valley and the surrounding heights of the Diablo Range define this high-country landscape in Santa Clara County. The terrain is characterized by complex ridgelines and deep canyons, with Seeboy Ridge and Castle Ridge flanking the drainages of Arroyo Bayo and Isabel Cr. Transport through this demanding topography relies on the winding San Antonio Valley Rd, which follows the contours of the land past Jack Canyon and Sugarloaf Mtn.
