» South Skyline Regional Map by MROSD:
Awesome map showing many parks managed by MROSD (Mid-Peninsula Regional Open Space Destrict). Long, interesting routes going through multiple parks can be chalked out using this map.
» Redwood Hikes Map: Bay Area Trail Map: Saratoga to Big Basin, First edition, 2010. This is an excellent map sold by Dave Baselt ($6.95 in Dec 2011). This map is useful for exploring many parks in this area. Highly recommended for avid hikers.
» Redwoodhikes Trail Map:
Great map showing many parks like Purisima Creek, Huddart, Wunderlich, El Corte De Madera, Foothills, Hidden Villa and Rancho San Antonio. Trail maps for individual parks are available online for free. However, the RedwoodHikes map shows the big picture and is helpful for planning hikes that go through multiple parks.
Route in brief: Saratoga Gap Trail (1.7 miles) → Bay Area Ridge Trail (0.3 miles) to reach Highway 35. Cross over the highway. Then enter Long Ridge Open Space Preserve. Follow Bay Area Ridge Trail (0.1 miles) → Achistaca Trail (1.7 miles). Then cross over Highway 9 and turn left on Skyline to the Sea Trail (0.5 miles) to return to trail head. The hike is shaded throughout except for short sections of Achistaca Trail and Summit Meadows Trail.
